RPM steps up to deliver a superior axle carrier design while using the larger outer bearings found in Associated’s #9730 axle carriers (common to some B4’s and all B44’s). The larger outer bearing supports the axle better, providing over 1/16” more axle contact than two 3/16” x 3/8” standard bearings, for smoother, longer lasting performance. With the larger outer bearing and RPM proprietary materials, we found the perfect blend of strength and durability for a whole range of Associated 1/10th scale electric vehicles!

RPM axle carriers are molded in black, factory-backed by our industry-leading warranty program and are proudly manufactured in the USA!

Tech Notes: RPM #70172 Axle Carriers (bearings not included) are stock replacement parts for the B44 while the SC10, SC10.3, T4 & B4 may require the use of Associated #7935 Outer Bearings & Associated #7933 Crush Tubes. RPM rear axle carriers fit all versions of the vehicles listed.
