This aftermarket aluminium low-centre adapter set is intended for TRAXXAS SLASH 4X4 applications and combines an aluminium adapter body with hardened 32-pitch steel spur and pinion to preserve mesh stability under operational loads. The set consists of a 56T spur and a 14T motor pinion to create a direct gear pairing commonly used when tuning acceleration versus top speed on the 68086-21 platform.
The hardened steel gears are specified for improved wear resistance while the aluminium adapter reduces flex and helps ensure consistent gear alignment. Supplied as a single set, the unit is supplied for hobbyist drivetrain tuning where pinion swaps are used to refine motor load and vehicle response.
Use the kit to systematically evaluate gearing changes; example ratios are 56T with 13T=1:4.307, 14T=1:4.000, 15T=1:3.733, 16T=1:3.500, 17T=1:3.294, 18T=1:3.111, 19T=1:2.947, 20T=1:2.800 to determine the best compromise for motor rpm range and track conditions.
