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! This muscle-laden product is a rear bearing carrier for the Slash 4×4, Telluride, Nitro Slash, Stampede 4×4 & Rustler 4×4. The stock version simply can’t handle hardcore carnage like RPM products can. RPM's 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 the bearing carriers are designed to hold the bearings tight, meaning absolutely no bearing slop in the bearing bores! RPM also reduced the end-play 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 the trademark blend of RPM nylons that make their products so indestructible. RPM's carriers are so strong (like all RPM molded products) that they back them with a limited lifetime warranty against breakage!While these bearing carriers were designed with the Traxxas Slash 4×4 in mind, they are direct replacement parts for all of the following vehicles as well: Stampede 4×4, Rustler 4×4, Telluride, Nitro Rustler, Nitro Stampede, Nitro Sport, Rad 2, Hawk 2, Eagle & Blue Eagle LSII!Tech Notes: RPM Rear Bearing Carriers replace Traxxas stock #1952 & #1952X. RPM Rear Bearing Carriers are sold without bearings.
