If you’re encountering steering arm breakage with your stock Super Rock Rey’s spindle set, or if you’re looking for a strong, aftermarket replacement option, RPM has the alternative you’ve been looking for.
RPM Spindles for the Super Rock Rey have reinforced steering arm ribs that triangulate further than stock, strengthening the steering arm to unbreakable levels! We also increased the amount of support material surrounding the axle bearings to improve overall strength and crash survivability.
To further the aesthetic appeal, we’ve redesigned the brake caliper mounts for a cleaner, more finished look and made them lighter. While we were at it, we also replaced the stock, heavyweight 4mm. king pin retaining screws with lightweight 3mm versions. This simple screw size change reduces the overall unsprung weight of the spindles by 4 grams (2g. per side) without compromising strength!
RPM Spindles for the Losi Super Rock Rey utilize stock suspension geometry and are molded from our indestructible blend of engineering grade nylons for the best possible aftermarket option you can find!
Tech Notes: The RPM Super Rock Rey Spindle Set replaces stock Losi #LOS254055 and are sold in pairs (1 left and 1 – right). RPM Caliper Mounts replace the stock mounts from Losi #LOS252109 (calipers not included). Bearings are stock and are not included.
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).
