Description
Overview
Eliminate the weak link in your Redcat Ascent 18's drivetrain with the Hot Racing Hardened Steel Universal Center Driveshaft U-Joint Axles. Precision-machined from hardened steel and aluminum with a durable black finish, this center driveshaft set replaces the stock RER28867 axles with a stronger, more reliable u-joint design built to handle the abuse of scale crawling and trail driving.
The hardened-steel u-joint construction resists the bending, twisting, and breakage common in stock plastic or pot-metal driveshafts, while the smooth pivoting joints maintain consistent power transfer through full suspension articulation. A must-have upgrade for any Ascent 18 owner pushing the platform on technical lines.
