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.

I've bought like 20! Love them!!!
Size: Large, Pattern Name: Pack of 1
My dog is obsessed with this ball! Glow in the Dark is super bouncy, easy to spot at night, and tough enough to handle rough play. Perfect for evening fetch sessions—fun for both of us! We have bought about 20 of these so far. I always bring my dog to play fetch at night, and this is perfect if you're playing in a field or beach. Glows in the dark so both you and your dog can see it. The size of the ball is great for my big dog. It is also the perfect type of silicone so that my dog cannot easily tear it apart and chew it, which is GREAT! We do NOT want our dog's ingesting silicone at all. If you have a ball chewer, this ball is perfect and durable. Chewing ability is good and is not too tough but tough enough.

Cane Corso approved....
Size: Large, Pattern Name: Pack of 1
My Cane Corso loves this ball!!! She carries it around in her mouth like a round pacifier. Sometimes I'll wake up with the ball next to my head on my pillow. Lol This is the third one I've bought. She doesn't destroy them at all . Somehow she loses them. Yesterday she had two floating around. Lol. Earlier I gave her one of those hard rubber balls with feet... She destroyed it within minutes. She can skin a tennis ball and chew it in half in about 5 minutes. This ball is by far a favorite toy of her's. And she doesn't chew it to bits . And it glows in the dark which is fun for playing fetch at night. It's very easy to clean. Sometimes I put little snacks inside for her while she's laying down with her ball. I will definitely keep buying these balls everytime we lose one . They make her happy. And that makes me happy.

BEST GLOW BALL! MY COLLIE BLUE HEELER MIX IS OBSESSED
Size: Large, Pattern Name: Pack of 1
Well if I could just say...Mommas a fan too....BUT I think my dog should be the sponsor of CHUCKIT because he owns everything and he BREATHES, DREAMS, RUNS with #chuckit balls!! Since 8wks. old & Now 10 yrs young, BDAY=8.10.26....he wakes up with it in his mouth and falls asleep with IT! I HAVE THEEEE PROOF LOL SERIOUSLY OBSESSED! #chuckit #makemydogyoursponsor WE HAVE EVERY BALL X10 FOR SOME, launchers, bucket o balls , you name it so yeah #obssesedisanunderstatement #bordercollieblueheelermix #HARLEY ♡ nice colors and the durability is amazing 👏 know if you have a chewer I'm not sure because he just likes to catch the ball and then chew it sometimes and then leave it alone, until next time around. But the GLOW BALL just being cewed for so long and the textire is obviously different so it does end up cracking and you throw it away, definitely different rubber but highly recommend them both actually ALL of them👌🎉🥳🫶🏼 my Sisters 2 yr old pit destroyed them in minutes but only FOR PLAY , so IF YOU DONT WANT THAT BALL chewed to pcs. Put it up LOL and oh all of the balls EXCEPT the GLOW BALL stay true to form and durability, for real Harleys had some of them for years!! And nothing wrong with the CHUCKIT ball 10☆☆☆☆☆☆☆☆☆☆ SIZE is perfect too he love the medium 2.5" ball. Perfect for catching for hrs on end. You also have a choice you can get squeaky, crunchy,or nothing or glow in the dark, 3 sizes to fit your pupper.. .. so many choices and it doesn't have to be a ball you can pick from a ton of toys ' tuggers ,launchers and indoor toys too. As for the Chew resistance...mm touchy...like I said. Aggressive chewer are more likely to tear it up way quicker than the just playing mainly like I want to fetch dog. Either way. I dont purchase any other brand besides chuck it. Has always my pick, like 20+ yrs now lol. Hands down. This is not a paid thing or promoted or whatever. Just felt i should review for chuck it♡ to date has made my dog happy and healthier for years to come♡ thanks

These are great!
Size: Medium, Pattern Name: Pack of 2
My dog loves these and now won't play fetch with any other ball. I love that they glow bright so we can play fetch after I get home from work (it gets dark around 5 now). The dog and I both like that they whistle. They also squish easily and he loves to chomp on them while he runs around. Only reason I took off a star is because he chewed a piece of it off and now it doesn't whistle or fly as far. That being said, it seems to stand up well to all the chomping he does on it. I should not have left him alone with it, I think he held it down and pulled on it. If your dog usually makes it his mission to destroy things I wouldn't leave him alone with it, other than that I absolutely recommend these. Update 12/12/20: I got another dog last year and he also loves these balls. Probably the favorite ball for both dogs, they go into hyperdrive when they see them. New dog tends to be more destructive than the older one and I still don't leave them unattended with these balls, but new dog has not destroyed one. I made the mistake of leaving one in the Chuckit overnight once. Ball was wet from playing in the snow and became lopsided. Now doesn't fly very well but my weird dog still likes it. It is also starting to dry out and crack. None of the other glow balls have done this, I'm assuming it is also from leaving it in the Chuckit overnight. Other than that, these balls are great. I did read a few reviews that said charging them with UV light made them stay brighter for a longer period, but I did not notice a difference in my quick test of this theory. Just keep a good flashlight with you and brighten them up as needed.
