Let's face it: breaking parts sucks. When a part fails, the day is over. Not when your ride is equipped with RPM performance parts. Our newest muscle-laden product is a rear bearing carrier for the Slash 4x4. The stock version simply can't handle Short Course carnage like RPM products can. Our version is 100% stock geometry-perfect, but with a few tweaks to improve durability significantly. A ring surrounds the bearing bores, providing additional rigidity while a redesigned camber rod mounting boss helps disperse impact energy more evenly throughout the length of the carrier's arm. Additionally, the bearing bores in our bearing carriers are designed to hold the bearings tight, meaning absolutely no bearing slop in the bearing bores. We also reduced the endplay of the axles by approximately 1/64”, keeping your rear end tracking perfectly like it's supposed to. Obviously they wouldn't be perfect without our trademark blend of RPM nylons that make our products so indestructible. Our carriers are so strong (like all RPM molded products) that we back them with a limited lifetime warranty against breakage. While we designed these bearing carriers with the Traxxas Slash 4x4 in mind, they are direct replacement parts for all of the following vehicles as well: Nitro Rustler, Nitro Stampede, Nitro Sport, Rad 2, Hawk 2, Eagle and Blue Eagle LSII. If you're tired of ending a fun day due to breakage, we're here to solve that problem. Check us out, you'll be glad you did.
