RPM Spindles for the Super Rock Rey have actually strengthened guiding arm ribs that triangulate even more than stock, reinforcing the guiding arm to solid levels! We likewise increased the amount of assistance product surrounding the axle bearings to improve general strength and crash survivability.

To even more the visual appeal, we've revamped the brake caliper mounts for a cleaner, more finished look and made them lighter. While we were at it, we likewise replaced the stock, heavyweight 4mm. king pin retaining screws with light-weight 3mm variations. This basic screw size modification decreases the general unsprung weight of the spindles by 4 grams (2g. per side) without compromising strength!

RPM Spindles for the Losi Super Rock Rey make use of stock suspension geometry and are formed from our unbreakable blend of engineering grade nylons for the best possible Made in the USA aftermarket alternative you can find!

Tech Notes: The RPM Super Rock Rey Spindle Set changes 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 consisted of). Bearings are stock and are not included.

Weight Reduction Tips: Unsprung weight can be decreased by as much as an extra 2 grams just by replacing the six M3 x 10mm cap heads screws protecting the calipers to the caliper mounts with M3 x 8mm buttonhead screws (not consisted of). At the same time, leaving the caliper plates and calipers off totally will net an even larger unsprung weight-savings gain (at the expense of scale look).
