TRAXXAS Slash 4x4 Front CVD Drive Shaft & Knuckle Arm by GPM SSLA1280FH21  [SSLA1280FH21]

Front CVD drive shaft and knuckle arm

This 12pcs upgrade set is a front axle replacement designed for TRAXXAS Slash 4x4 platforms by GPM, intended to reinforce front-end durability and maintain reliable steering geometry after heavy use. The kit combines hardened steel and 6061 T6 aluminum components to balance strength with reduced unsprung mass.

Key construction details from the kit: the CVD shafts use hardened 45# steel mating parts paired with aluminum 6061 T6 components, and the knuckle arms are machined from 6061 T6 aluminum for increased wear resistance. The central axle section is thickened to 6mm to better absorb impacts from high-speed landings, and spring steel hexes are fitted to stabilize the interface under load. Bearings included in the set are sized for smooth rotation at the wheel end.

Installation and tuning notes: the tie rod angle can be adjusted using the multiple positioning holes on the knuckle arm to fine-tune ackermann and steering throw. When replacing stock parts, verify spline engagement and bearing seating before run testing, and recheck wheel alignment after the first run. The thicker axle and hardened steel interfaces reduce deformation risk, which helps retain consistent steering response during jumps and rough terrain.

This kit serves as a durable front-end upgrade for Slash 4x4 drivers who need reinforced CVD elements and firmer knuckle mounts to manage impact-prone driving while keeping steering tunability.
