GPM Racing Aluminium Front C-Hubs+Knuckle Arms+Spindle Gear+Cvd+Steering Link - 61pcs Set for Traxxas 1/10 TRX4 (TRX4H100F)

Front C-hub and knuckle assembly for TRX-4

This front-end upgrade kit is intended for TRAXXAS TRX-4 Trail Crawler models and is identified by part number TRX4H100F. The set groups aluminium C-hubs, inner and outer knuckle parts, spindles, front CVDs and a steering link into one installation package to modify steering geometry and shock placement for trail and rock crawling use.

Key mechanical notes: the C-hubs are machined from high-tensile aluminium and use Delrin collars in the positioning holes to reduce metal-on-metal friction where tie rods and shock mounts pass through. The lower section of the C-hub is reduced to create extra clearance under the body. Knuckle components increase internal gear pitch and diameter and lower the axle center by the stated amount to raise body clearance, and the kit permits repositioning of shock mounting points so dampers sit slightly outward rather than perfectly vertical to improve lateral stability when tuning ride height.

The kit is adjustable where indicated by the source parts list: tie rods and shock ends can be mounted in alternate holes to change steering toe and shock angle, and the set includes the fasteners and collars required to assemble the front C-hub, knuckles and spindle/CVD assemblies as supplied.

This product is for RC use only and is designed to replace or upgrade the front c-hubs, knuckle arms, spindles and steering link areas of compatible TRX-4 scale crawlers.

When installing, check fitment around the front suspension and steering link geometry, use the supplied Delrin collars where specified, and note that some GPM Racing pendulum-wheel variants listed by model number may not be suitable without additional modification; confirm clearance before final assembly.

What measurement should I use to confirm hub clearance?

Measure from the lowest point of the trimmed C-hub to the inside of your chosen tyre and wheel at full compression and droop to ensure no interference during articulation.

Are any parts supplied as spare items?

The kit contains the screws and Delrin/alloy collars listed in the parts content; keep spares of small fasteners if you run aggressive courses to reduce downtime.

How do I tune for reduced roll on rough lines?

Use the outer shock mount positions to increase lateral leverage and try firmer damping or higher spring preload to reduce roll while maintaining enough articulation for obstacles.

Which wheel types may need modification?

Some high-offset or pendulum-wheel designs that increase knuckle diameter could contact the hubs; check specific wheel part numbers and test-fit before finishing the installation. Write Product Review Please sign in your account before you can write any review. Sign In Close
