This assembly pairs a low-centre aluminium adapter with hardened 32 pitch steel spur and motor gears for the TRAXXAS Slash 4X4 Low-CG layout. The aluminium adapter adds rigidity to the mounting point while the steel 56T spur and 17T motor gear hold up under repeated pinion swaps and heavier brushless setups.
Fitting advice: the adapter takes the place of the original plastic adapter on the 68086-21 variant and positions the 56T spur for correct engagement with the motor pinion. After installation, hand-rotate the drivetrain to set a slight backlash, then fine-tune with shims or pinion height adjustments and check clearance to the chassis.
Tuning notes: the included 56T spur matched to a 17T motor gear gives a specific final drive; consult the ratio chart when changing motor gears to dial in acceleration or top speed for your track or park runs.
Ideal when you want a stiffer adapter and a wear-resistant steel gear pairing for the Slash 4X4 Low-CG 68086-21; always validate gear mesh and pinion selection before running.
