RPM Spindles for the Super Rock Rey are the upgraded alternative, with reinforced steering arm ribs that triangulate further than stock, strengthening the steering arm to unbreakable levels. RPM also increased the amount of support material surrounding the axle bearings to improve overall strength and crash survivability. RPM Spindles for the Losi Super Rock Rey utilize stock suspension geometry and are molded from an tough blend of engineering grade nylons for the best possible aftermarket option you can find.

Features:
Replaces stock Losi parts
Caliper mount replaces the caliper mount from Losi
4 grams lighter than stock
Redesigned and reinforced steering arms
Weight Reduction Tips: Unsprung weight can be reduced by as much as an additional 2 grams simply by replacing the six M3 x 10mm cap heads screws securing the calipers to the caliper mounts with M3 x 8mm buttonhead screws (not included). Alternately, leaving the caliper plates and calipers off entirely will net an even larger unsprung weight-savings gain (at the cost of scale appearance).
