True-Track Rear A-arm Conversion Kit
does all this come at a cost of added weight? The RPM Revo
True-Track Rear A-arm Conversion Kit actually weighs LESS than the
stock components it replaces! How much less? 16 grams PER SIDE! That’s
a total weight loss of 32 grams or 1-1/8 ounces! That means you get
perfect rear toe angles, added A-arm strength, bearings that are more
durable & longer lasting, an unbeatable breakage warranty and a reduction
in weight! What more can anyone ask for?
"Bump Steer" Defined: So what is "bump steer"? Bump steer is a change in the wheel's toe angle caused by the suspension moving up or down. Bump steer is inherent to the geometry of the suspension and steering system, and has nothing to do with turning the steering wheel. The effect of bump steer is for the wheel to toe-in or toe-out when the suspension moves up or down. This toe change or “steering” occurs any time the suspension moves, whether it is from body roll, brake-dive, or hitting a bump in the road. Bump steer is undesirable because the suspension is steering the car instead of the driver.
Bump steer is most common on the front end of R/C vehicles due to the unavoidable use of a tie rod to allow the vehicle to steer. Vehicles with a toe link rear end such as the Revo also have a similar amount of bump steer in the rear because the axle carrier isn't locked in a fixed position and is constantly being pushed and pulled by the toe link as the suspension moves up and down. This doesn't account for the slop in the rod ends of the toe link either, which causes even more toe angle changes. See for yourself. Look down at your vehicle from the top and compress the suspension. See what happens to the rear toe angle? Each wheel changes by at least a degree or two, which can be quite significant. Now imagine that amount of movement while your suspension arms are moving independently from each other and you'll understand why the True-Track kit is such an effective tool to dramatically improve suspension performance.

RPM Recommendations: The RPM True-Track System is designed to match RPM A-arms (Part #80212 & #80215 - Right Side & #80222 & #80225 - Left Side) & Axle Carriers (#80582 & #80585 - 1 package needed) currently available for the Revo. With the True-Track system mounted at the rear and a set of RPM replacement A-arms & Axle Carriers up front, you are assured the best performing & most indestructible A-arm / Axle Carrier combination possible!
Tech Notes: These rear end kits work on all versions of the Traxxas Revo, including the e-Revo and e-Revo brushless but depending upon the version, may shorten the wheelbase of the truck. One kit will complete the entire rear end of any Revo. These kits will not work in conjunction with Traxxas (#5356) 120-LT Long Travel Rockers. Due to the wide lower A-arm hinge pin configuration, some aftermarket wheels - in particular, 3.2" beadlock wheels, may not work with RPM True-Track kits. Check with the manufacturer of your aftermarket wheels before installing this kit.
Replacement Parts: If new bearings are needed, please see the replacement bearing kit #80570 shown with our Revo axle carriers below. New setscrews and bushing caps - RPM #80010 can be found on our T-Maxx pages here.
