The RPM True-Track Rear A-arm Conversion Kit for the Revo eliminates some of the biggest headaches associated with toe link rear ends. Rear toe angles are nearly impossible to set accurately and there isn't a gauge currently made that can accurately identify whether each individual wheel’s toe angle is set correctly in relation to the chassis. The RPM True-Track rear end kit completely eliminates the rear toe links, locking in the rear toe angle at a solid 1.5 degrees per side for a total rear toe-in angle of 3 degrees. By getting rid of the rear toe links, we’ve completely eliminated all rear bump steer! That means the rear toe angle remains consistent throughout the entire range of suspension travel, providing superior rear end tracking regardless of the terrain. Identical to our T/E-Maxx True-Track Kit, the Revo True-Track Kit retains the stock upper pivot ball in the new, ultra beefy RPM axle carrier to allow precise camber adjustments while the lower pivot ball has been eliminated in favor of a rock-solid 4mm diameter hinge pin that locks in the rear toe angles for race winning consistency (hinge pin replacement part #80970). All aspects of the RPM True-Track Conversion Kit have been beefed up for rugged durability and slop free movement throughout its range of travel. Additionally, we’ve incorporated our oversized bearings into the new RPM axle carrier design, providing an additional 2mm more bearing contact with the axle while doubling the bearing load rating & tripling the fatigue rating over the stock bearings.

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 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 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. 

What’s Included: Our Revo True-Track Rear End Kit consists of two upper rear A-arms, two lower rear A-arms, two beefy rear axle carriers, two outer 6x15mm sealed bearings, two inner 12x21mm sealed bearings, two aluminum pivot ball setscrews, two delrin pivot ball bushing cups, two M3x16mm shock mount screws, two 4mm diameter tool steel hinge pins & enough e-clips to get the job done (4 minimum).

The RPM True-Track Rear A-arm Conversion eliminates one of the biggest headaches associated with the incredibly popular Maxx line of trucks. Rear toe angles are nearly impossible to set accurately and there isn’t a gauge currently made that can tell the T-Maxx / E-Maxx owner if each individual wheel’s toe angle is set correctly in relation to the chassis. Our rear end kit completely eliminates the rear toe link, locking in the rear toe angle at a solid negative 1.5 degrees per side for a total rear toe of negative 3 degrees (of Toe-In), effectively eliminating rear bump steer! Our design retains the stock upper pivot ball in the RPM axle carrier to allow precise camber adjustments while the lower pivot ball has been eliminated in favor of a rock-solid, beefy 4mm diameter hinge pin that locks in the rear toe angles for race winning consistency. All aspects of the RPM rear end conversion have been beefed up for rugged durability and slop free movement throughout its range of travel. Additionally, we’ve incorporated our oversized bearings into the axle carrier design, providing 2mm more bearing contact with the axle while doubling the bearing load rating & tripling the fatigue rating over the stock bearings. So does all this add weight? Not a single gram! The entire RPM rear end kit weighs in exactly the same as the stock components that are replaced!

What’s Included: Our rear end kit consists of two upper rear A-arms, two lower rear A-arms, two beefy rear axle carriers, two outer 6x15mm sealed bearings, two inner 12x21mm sealed bearings, two aluminum pivot ball setscrews, two delrin pivot ball bushing cups, two 4mm diameter tool steel hinge pins & enough e-clips to get the job done (4 minimum).

Recommendations: The RPM True-Track System is designed to match the A-arms (Part #80462 & #80465) & Axle Carriers (#80582 & #80585) we currently produce for the T-Maxx. 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 durable A-arm combination possible!

RPM rear shock towers for the electric versions of the Stampede, Rustler & Bandit were designed with one thing in mind – rugged durability. Once again, we’ve exceeded our own expectations with this shock tower. While we’ve maintained all stock geometry on these shock towers, we’ve beefed them up in all the right places to eliminate annoying rear shock tower breakage. Our version of this shock tower uses an I-Beam construction that improves durability and rigidity as well. At the base of the shock tower, we’ve improved the screws’ head clearance of the bulkhead mounting screws to eliminate the bind normally associated with the stock rear shock tower. All these design elements combine to create the ultimate lightweight, bulletproof rear shock tower for the electric versions of the Rustler & Stampede.

RPM rear shock towers for the Traxxas Electric Stampede, Electric Rustler & Bandit are molded in black and are backed by our famous breakage warranty. These towers are direct replacement parts for ease of installation.

Tech Note: These rear shock towers can be used on the Traxxas Bandit. However, there are no provisions for a rear wing built into these shock towers.

(fits the Traxxas Nitro Stampede, Nitro Rustler & Nitro Sport)

RPM rear shock towers for the nitro versions of the Stampede, Rustler & Nitro Sport are designed with a twin I-Beam structure that significantly improves crash durability without altering stock geometry or rigidity. Additionally, we’ve altered the location of the on/off switch to be more accessible. The new location is ¼” lower than the stock version making it much easier to reach while the body of the truck is in place.

The RPM rear shock tower has been engineered with a wide, diamond-shaped opening that easily permits the stock easy-start connector to move through the shock tower allowing quick and easy removal and installation of the shock tower without disconnecting any wires.

For those Nitro Stampede owners, we added two body mounting holes in the rear shock tower so you can use 4 screws instead of 2 to secure the stock body mounts to the shock tower (additional mounting screws not included).

(versions for Electric & Nitro Stampede, Electric & Nitro Rustler & Bandit)

RPM shock towers for Traxxas 1/10th scale trucks are designed to add strength and support to the front-end suspension components of these great vehicles. Our shock towers maintain all stock geometry while adding much needed structural strength to this vital suspension component. Our design uses an I-beam structure that adds tremendous levels of strength and rigidity that is far superior to u-shaped or flat designs. Our front shock towers will not flex nearly as easily as the stock versions yet have enough give in them, which prevents breakage from hard impacts or crashes.

RPM rear A-arms for the electric versions of the Traxxas Rustler & Stampede are stronger and more durable than stock versions, but we’ve also managed to eliminate over 7 grams of weight per arm! That’s 14 grams of unsprung weight eliminated with a single pair of rear A-arms! Coupled with a set of RPM front A-arms, the total weight loss exceeds 24 grams or almost a full ounce! We accomplished this without creating any weak points nor are our A-arms any more flexible than the stock versions. Additionally, we’ve adjusted the shock mount locations slightly to allow more noticeable tuning adjustments when using the inner or outer shock mount holes (while the center hole remains in its stock location). While we were at it, we eliminated over 0.030” or 1/32” of slop from the inner arm mount and more than 0.010” or slightly less than 1/64” of slop at the outer hinge pin for an ultra-smooth, slop-free suspension system.

RPM front A-arms for the electric versions of the Traxxas Rustler & Stampede are built to withstand some of the toughest abuse. Incredibly, we were able to shave some unwanted unsprung weight as well. RPM Front A-arms are nearly 25% lighter than stock versions of the same A-arms, yet the RPM versions are backed with our world-renowned breakage warranty. Additionally, we’ve increased clearance areas in the outer portion of the A-arms to allow increased droop travel when used in conjunction with RPM oversized bearing carriers (RPM #80372 & #80382). RPM front A-arms for the Electric versions of the Traxxas Rustler & Stampede are sold in pairs and are available in either black or blue. These A-arms are molded with what is fast becoming an RPM trademark design of angled leading and trailing edges to reduce frontal edge mass and improve the a-arm’s ability to ride up and over tall obstacles instead of slamming into them. RPM A-arms are extremely rigid for superior ride and stability over the roughest tracks and terrain.
