This is an optional RPM Hybrid Gearbox Housing and Rear Mount Kit, and is intended for use with the Traxxas Slash, Stampede, e-Rustler and Bandit 1/10 scale vehicles. The RPM Hybrid Gearbox Housing and Rear Mounts for Traxxas 2WD vehicles is designed to solve a multitude of issues with stock and other aftermarket transmission housings. This RPM gearbox housing and mounts are a blend of aluminum and molded nylon parts for the perfect combination of strength, durability and heat dissipation.

Each RPM Gearbox Housing kit is available in black, green or blue and comes will all necessary mounting hardware and instructions. Whether racing or bashing, the RPM Gearbox Housing is one of the least expensive yet most valuable options you can buy! Every RPM Gearbox Housing kit is proudly designed and manufactured in the USA! 

Aluminum Motor Mount Features:

  • Manufactured in the USA from 3mm thick, 6061 T6 aluminum for serious strength and durability.
  • Locks in gear mesh for worry-free pinion to spur settings, eliminating fears of exploding spur and pinion gears from an overheated stock transmission case.
  • Offers significant motor heat dissipation for cooler motor temperatures, unlike stock plastic motor plates that insulate the motor.
  • Not integrated with the rear bumper mounts, meaning rear impacts will not bend the motor plate, (when used with a rear bumper or bumper mounting system such as RPM80902 or RPM80905).

Molded Gearbox Housings Features:

  • Molded from our blend of bulletproof nylons in three popular color choices for guaranteed durability, strength and style.
  • Retains stock bumper mounting holes for positive, solid support of any bumper or wheelie bars you may choose.
  • Retains a stock “cover” for the motor, adding motor protection where most aftermarket housings leave the motor completely exposed to rear impacts.
  • RPM modified their housing to eliminate the huge bottom hole in the stock housing, keeping your internal gears cleaner, longer.
  • Quiet! With a completely enclosed gearbox housing, you’ll no longer have the loudest transmission on the track.
  • Redesigned exterior features are smoother; making it less likely dirt will adhere or build up on the case.
  • Separate housing and rear mounts means transmission maintenance won’t affect suspension settings.

Molded Rear Mount Features:

  • Separate from the gearbox housing and easy to access. Each mount is individually accessible and removable without removing the transmission or vice versa. Simply unbolt 2 screws (and a hinge pin) to remove an A-arm mount or 6 screws to remove the transmission!
  • Sold with two sets of rear mounts in each package – 0° and 3° rear mounts are included.
  • Molded from the RPM blend of ultra durable, long lasting, bulletproof nylons.
  • Molded mounts means tighter tolerances and less slop than with machined components for better camber and toe angle retention.

Great case if you want to break gears every run metal gears to . The case flexes and breaks the idler gear then the rest . I mean rpms a good brand but why do we need flex in a transmission case we need quality in the case . Only get if you want to use more money into gears than what the case even costed . Don’t get this I’m switching out ASAP.

Would highly recommend. This case takes a beating. It is also easy to take apart to replace parts inside. Have had it apart for several drive gear replacements, and have no complaints.

Please save yourself time and money and don't buy this RPM transmission box. It is using the same flexible plastic that gives up underload causing space in the mesh of the internal gears resulting in stripping them. Very disappointed because of this otherwise it could have been an excellent transimission.

You will become an expert at rebuilding it over and over again. Flexible plastic on RC cars is great, but not in the gearbox.
get the aluminum case and save money on many gearsets.

there are better....over all it is a good case. and I like the case. but there are fitment issues with these cases and 2wd stampede's. but nothing a little sand paper or a hobby knife cant fix.

I got the transmission case a couple months after they came out. so long term it does well but the biggest thing I have a problems with is the "jam nuts". off the hop invest in some longer screws, low profile lock nuts and some Teflon tape. because the a-arm mounts move. adding about 5 degrees toe in per side......imo it is just as importiant as the transmission case itself specially when im already running 5 degrees toe in on my truck as is. so 10-12 degrees toe in just not good for anything

Great gearbox. The aluminum motor plate gives much more heat dispersion than stock. Running this in Project 70 race truck, and it has already won a 1st. You get what you pay for. Recommend!

Two weeks in and still running strong. Jam nuts can be a pain and it should include ALL necessary screws but it doesn't. Holding up very nice against my bashing and 3 to 5+ foot drops will up date this when I find a way to nuke it.

Nice case. Take the time to read the instructions when assembling this case, more/better pictures would have been more beneficial. I've rebuilt by gearbox several times in the past, so it wasn't too bad. The hardest parts were making sure the correct length screws are used (Note: the screw diagram on the instructions is not true to scale, use a ruler/caliper) and putting on the "jamb nuts" to secure the four 4mm bolts that hold down the rear mounts/gearbox.

Overall build quality is very good and everything fit very well. It's felt a little heavier than stock case (due to aluminum plate) but definately lighter that a full aluminum case. Outside of some test runs inside the house, I have not raced with this new setup yet. We'll see how durable the case is.

This gear box is good for XL5 but has to much flexibility for high speed VXL. The new 272R is hard to beat for high power but for bashing at under 30mph the rpm trans is ok.?

This transmission case flexes too much on my rustler vxl and constantly breaks my gears because of the flex. Would not recommend it. Worst 30$ ever spent
