Our globally acclaimed 1,000HP+ Capable Nissan Skyline Dog Engagement Gearset is an essential addition for any automotive enthusiast!

We're immensely pleased with its design, and we're equally impressed by how effortless it is to maintain the transmission when necessary.

Each gear is meticulously pressed onto the counter shaft and main shaft individually, ensuring that every component can be replaced separately with utmost ease if required in the future.

Featuring universal fitment for RB25, RB26, RB30, and VG30 transmissions, our gearset boasts a heavy-duty design crafted from top-quality billet steel materials. Precision machined using CNC technology, each component undergoes surface grinding after heat treatment to minimize noise and maximize strength. Comprehensive instructions are included for seamless installation.

For those seeking enhanced performance, we offer an optional Isotropic Superfinishing process.

Despite its exceptional capabilities, our Skyline Dog Engagement Gearbox remains competitively priced, making it an accessible choice for those in search of a high-horsepower capable transmission that is easy to service.



What sets our Dog Engagement Gearset apart and why should you consider it?

The standout feature of our Dog Engagement Gearset lies in its unparalleled serviceability. With each part fully removable, maintenance becomes a breeze, providing enthusiasts with unmatched convenience and flexibility. This capability allows for swift repairs without the need to dismantle the entire gearbox, reducing downtime and ensuring quick return to the road or track.

Furthermore, the gearbox's ability to accommodate shifting at over 9,000rpm adds to its performance prowess, catering perfectly to the high-revving engines commonly found in racing and high-performance setups. Paired with lightning-fast shifting, this feature elevates the driving experience, delivering seamless power delivery and exceptional responsiveness.

The convenience doesn't stop there. Our gearset comes as a comprehensive 100% drop-in kit, complete with all necessary components for installation. From gears to shafts, dog rings, and hubs, everything you need for a complete upgrade is included, eliminating the hassle of sourcing additional parts separately.

Notably, our gearset features 6 dogs per gear, surpassing the standard 5-dog setup commonly found in other Skyline Dogbox Kits. This enhancement translates to even faster and more precise shifts, underscoring our dedication to providing top-tier performance and user experience.

With a focus on optimizing shifting speed and precision, our Dog Engagement Gearset stands as the ultimate choice for enthusiasts seeking to elevate their Nissan transmission for high-performance applications.

We typically suggest ANYONE who has intentions of using the Transmission for High Power / Hard Launches to go with the 26 Spline Input Shaft, especially if the car is heavy and has a larger capacity motor (stroked, or 3L+). The Factory 24Spline Input shaft is not suggested for application's over 600hp unless used in roll racing or "street" use, then you can avoid going the Larger Input Shaft in some conditions.

Our 26 Spline Input shaft would be best for those seeking maximum strength and push the limits of our Transmission well beyond 1000HP.

1st to 4th Gear Ratios:

  • 1st – 2.583 (Mainshaft 31 / Countershaft 12)
  • 2nd – 1.625 (Mainshaft 26 / Countershaft 16)
  • 3rd – 1.263 (Mainshaft 24 / Countershaft 19)
  • 4th – 1.000 (Mainshaft 24 / Countershaft 24)

5th Gear Ratio Options:

  • Short – 0.814 (Mainshaft 22 / Countershaft 27)
  • Long – 0.677 (Mainshaft 21 / Countershaft 31)

MS = Main Shaft Gear Count
CS = Counter Shaft Gear Count

*Take note, when using the short ratio 0.814 it is required to slightly die-grind the Retainer Plate near the gear for clearance to the teeth as the gear is larger.

**Using this Gearset will result into your FACTORY 0.76 Ratio 5th Gear becoming a 0.55 Ratio because of the fact we run a true 1:1 Drive Gear (4th Gear) - We suggest using 5th only for the Highway if you run this kit,  our optional Dog Engagement 5th gear with 0.814 ratio (1-5 Short + Reverse) for circuit use and 0.677 1-5 Long + Reverse ratio for highway use to go with this kit, with Dog Engagement Reverse.

We now offer Isotropic Superfinishing on all our Speedtek Products.
(This process will increase the time from when we could dispatch the kit, please email us if you have any questions)

Superfinishing is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone to grind the gears and other parts ; this layer is usually about 1 μm in magnitude. Superfinishing, unlike polishing which produces a mirror finish, creates a cross-hatch pattern on the workpiece.

Advantages of superfinishing include: increasing part life, decreasing wear, closer tolerances, higher load bearing surfaces, better sealing capabilities, and elimination of a break in period.

Our solid 6-month unconditional warranty program for all our manufactured gearsets, you can be confident that your investment is well-protected. 

Our extended warranty program is available, for more information : Extended Warranty Program now Available with our Performance Transmiss – Speedtek Auto Racing


We provide installation instructions for all our Dog Engagement Gearsets, please email us for this when you receive your kit.

Can’t recommend anymore
Color: A-Silver, Style: Button, Color: A-Silver, Style: Button
Updated 2/25/25 - after being contacted in January by Casabrews and keeping the machine rather than returning it… it now leaks water all over the counter out of the bottom of the water container when I’m adding water and when I’m making espresso. I’ve taken it apart and put it back together - didn’t help. Video attached. Turns out the Bambino is worth the price. I do not recommend this machine - it is NOT made to last. Alright… longest story short - I’m directly comparing this machine to what seems to be the highly coveted Breville Bambino Plus that costs 3.6% more than this machine. For the overall response without reading any further - get this one over the more expensive option! For the longer version keep reading. I need a new machine to replace my very old espresso machine that isn’t working properly anymore. I didn’t want to go too crazy with spending if I didn’t have to. So many people seem to LOVE the Bambino Plus. I bought one three days ago. I returned it two days ago. It made espresso, but not well, and the auto milk frothing, two out of three times, did not stop and boiled fairly hot milk over the pitcher and everywhere. Not a good feature. Not worth the extra $200 they add for that feature over the regular Bambino. The regular Bambino is still slightly more than 2x the price of this machine. This morning out of frustration I opened Amazon and looked for the highest rated/reviewed machine that I could get TODAY before 3pm. Helped narrow it down out of thousands of machines quickly. So here we are. Why 3 stars? Here are the pros and cons for me (and mind you I’ve made ONE drink - the video that is attached). Pros: It’s cute / kinda retro looking with the guage. Which due to filming and watching the coffee flow I realize I didn’t even look at it so I don’t know if it is helpful or not yet. It’s very compact and is smaller than most drip coffee machines. It should cause zero space issues for anyone. It seems fairly sturdy despite the price. It didn’t rattle my cup around etc. Yes I had to hold onto it for the portafilter - but not in an agressive way. The Bambino felt like I had to hold onto it more so. The box and the directions it comes with - they really do cover a lot of information for people who are new to espresso making - which I think is a nice added touch. Cons: The steam wand, turned all the way up, does a terrible job at frothing. If you want hot milk that doesn’t get any real texture - that was my experience. Again - first use - but I steam milk everyday and this steam wand was a let down. The portafilter, the baskets, the "tamper"…. All three need to be replaced immediately. The portafilter is very lightweight and the baskets have to be turned and placed inside with little slots. They feel very low quality overall. The tamper is the flat side of a plastic spoon. I didn’t open the bag with the spoon or the single basket - I didn’t bother trying to use it. I used one I already have. No milk pitcher included. Casabrews does sell upgraded portafilters and baskets and a tamper. I don’t know if I am going to keep this machine (I make milk drinks all day and that steam wand is rough for me) - but if I do - I will spend the extra for the better accessories (bottomless portafilter - non pressurized basket etc). For a budget machine though - overall I’d say this machines reviews are pretty accurate. I did follow all the instructions - and I’m going to go make another coffee now. Update: 1/7/25 - I will still leave my rating at 3 stars because of everything I said a couple of days ago. After a couple of days with this machine and many espresso drinks made - I wanted to add a couple things. First - it really does not froth milk. I’ve tried three different kinds and it just gets it really hot with zero texture and zero froth. Massive letdown for me since I like milk drinks. I also meant to mention in the first review, the steam wand is not the insulated kind - so it gets VERY hot. Just something to be careful with if you aren’t aware that not all steam wands are made the same. I tested the machine with coffee ground for espresso machines and it did not like it. With the pressurized basket it comes with, the machine does better with a more coarse grind (similar to a drip coffee/sea salt texture grind). That would be a plus if you want to use pre ground coffee from the grocery store. The instructions for the machine also say that you cannot use the steam wand and then make another espresso shot right after. If you try to do that the machine goes into heat protection mode. It locks the machine and there is a sequence you run that ends up using a lot of water in your reservoir to cool the machine back down. If you wanted to make a milk drink for someone and make another drink right after for someone else, you can’t. Or you can’t without either waiting an unknown amount of cool down time OR running the routine to cool the machine first. HOPEFULLY this review helps in someone’s decision making. If you ONLY drink espresso shots - this machine is probably tidally worth it! If you like milk drinks…. Maybe try it out and see if you have better luck than me. Today I had to use my old espresso machine’s steam wand to go with my espresso shot from this new machine.

It is easy to use, heats quickly and prepares a coffee with a very good flavor and an excellent cream. The build quality feels solid and cleaning is easy. It has exceeded my expectations and I use it every day. I would recommend it to anyone who wants to enjoy quality espresso at home.

CASABREWS customer service is outstanding.
Color: A-Silver, Style: Button
I purchased the CASABREWS CM 5418 from Amazon a little over a year ago. For the price it is a very good, easy to use, compact, Expresso/Capaccino coffee maker. Although the unit worked to make satisfactory Expresso, the pressure gauge stopped working after a few months and the water extraction was not complete with each brew. Even though I was aware the unit was out-of-warranty, I decided to contact CASABREWS Customer Service Support via Email, to inquire about the issues and what possible remedies there might be. JoJo, from CASABREWS Service Team, replied quickly and although there were some “Flushing Procedures I could try”, JoJo immediately stated that a manager had authorized a replacement unit to be sent to me. Amazon delivered a new unit one day after our Email conversation was completed. I can only say that CASABREWS customer service is outstanding. Their “real” concerns about inconveniences I may have endured was refreshing. Kudo’s to CASABREW!

Rich Espresso, Great Value
Color: A-Brushed Silver
I’ve been using this espresso machine for a little while now and honestly I’m very happy with it. I wanted something simple, affordable, and easy to use without spending hundreds of dollars on a fancy coffee maker, and this one does exactly what I need. The espresso comes out rich with a nice crema and the milk frothier works really well for lattes and cappuccinos. It heats up fast and doesn’t take much effort in the morning, which I love. One of my favorite things is how easy it is to clean and maintain. The removable water tank helps a lot and overall it doesn’t feel like a machine that requires constant work. For the price, the quality is surprisingly good. It looks nice on the counter, feels sturdy, and makes coffee that tastes much better than I expected

Very good
Color: A-Brushed Silver
Here its my review for this espresso machine. The stainless steel design looks modern and premium, and it fits perfectly in small spaces without taking up too much room. The espresso comes out with a rich flavor, and the milk frother works great for making lattes and cappuccinos at home. I also like the pressure gauge because it helps monitor the extraction process. Perfect option if you want café-style drinks without spending a fortune on a large machine. Easy to use, easy to clean, and looks beautiful on the counter.
