RPM True-Track Rear A-Arm Conversion Kit for Traxxas Revo (Black)
About this part
So 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.

Fit perfect for Revo 3.3 and very cool itam I'm I recommend this :)
Both threads on axle carriers cross threaded. I read the instructions warning about this and to start by threading counter clockwise first. Didn’t matter. Rly seems like they were messed up from the start. Also bearing don’t come lubed. Would be nice if it mentioned this. I wanted to run now have to wait on lube. First RPM product I have not been happy with. Wish I would have just stayed stock in hindsight.
Perfect upgrade to the rear end of my Revo 3.3. Everything in this kit is way beefy and RPM quality you would expect. Bearings provided are huge compared to stock. For the money this kit cannot be beat. I have used my Revo for hard bashing/driving multiple days in different terrains and rear rpm set up is perfect. I also noticed much better suspension feel and better handling.
Reviewers of this black RPM True-Track rear A-arm conversion kit for the Traxxas Revo describe a mixed experience. Two of three rate it 5/5, praising the fit on the Revo 3.3, the beefy components, larger bearings than stock, and improved suspension feel and handling after hard use across terrains. The one 2/5 review reports axle carrier threads arriving cross-threaded despite following the instructions, and bearings shipping without lubrication, which the reviewer felt the instructions should mention. Overall the reviews agree on fit and build quality, while the single negative review points to a possible quality-control issue at assembly. Sample size is small.
