GPM Racing Aluminium F&r Upper+Lower Arms+F&r Adjustable CVD Drive Shaft+Aluminum 7075-T6 Hex Adapter+Wheel Lock+Stainless Steel Adjustable Front Steering Tie Rod (Widening Kit) for Traxxas 1/10 MAXX

CNC-inspired widening arms and CVD reinforcement

The GPM TXMS100N is engineered as a widening and reinforcement kit for TRAXXAS 1/10 4WD MAXX monster trucks, delivering a matched set of front and rear upper and lower arms plus adjustable CVD drive shafts. The assembly is intended to push the wheel track outwards by 20mm per side, improving lateral stability while the thicker 8mm axles and hardened joint inserts help maintain driveline integrity under increased loads.

Engineering notes: main structural components are produced from 6061 T6 aluminium for an optimal strength-to-weight compromise, with delrin collars and 4mm delrin shims included to control play and ensure consistent fitment. Fastening uses pin retention with small screws to limit thread wear, while multiple damper mounting locations provide setup flexibility. Hardened steel joint inserts work with alloy bodies; axle diameter has been increased from 6mm to 8mm to improve torsional capacity. Bearings sized for the larger axles are supplied to match the upgrade.

For technical hobbyists seeking a robust widening upgrade, TXMS100N pairs aluminium arms with reinforced CVDs and precision hardware to widen the MAXX track while preserving drivetrain strength for demanding use.

What tolerances are addressed by the kit to prevent slop?

Delrin collars and 4mm delrin shims are supplied to correct mating tolerances, and pin retention with small screws is used to reduce thread wear and maintain consistent joint positioning.

How does axle size change affect load capacity?

Increasing axle diameter from 6mm to 8mm increases cross sectional area and torsional stiffness, which improves durability under higher torque and lateral loads.

Are the hex adapters and wheel locks compatible with standard MAXX hubs?

The kit includes 7075-T6 aluminium hex adapters and wheel locks designed to mate with common MAXX hub patterns; verify hub dimensions and secure with the supplied hardware.

What setup advice do you have after fitting?

After installation re-check camber, toe and damper positions; use the multiple damper mounts to dial roll centre and fine tune for the intended driving surface. Write Product Review Please sign in your account before you can write any review. Sign In Close
