TRAXXAS TRX4 TRAIL CRAWLER Spring Steel Upper & Rear Suspension Links by GPM TRX4160ST  [TRX4160ST]

Spring steel upper & rear links for TRX4

This 7pcs link set upgrades the suspension tie rods on TRAXXAS TRX4 Trail Crawler scale models, using spring steel construction to increase durability and steering feedback. The set replaces the factory-diameter tie rods and provides adjustable lengths and reverse-threaded ends to fine-tune toe and wheelbase for trail and crawler setups.

The kit is intended for scale RC use only and supports adjustments to turning sensitivity and wheelbase geometry without modifying axle housings. Key measured midpoints are provided for alignment: front upper 80.5mm, front lower 114.8mm, rear upper 139mm, rear lower 135.5mm. The tie rod diameter is thickened from the original 5mm to 6.5mm for increased stiffness.

Use this set where increased tie rod stiffness and precise length adjustment are needed to refine steering response on TRX4 trail and crawler builds; installation generally follows stock link removal and replacement procedures with attention to matching midpoint lengths for correct geometry.
