TRX4M 52mm Machined Aluminum Shock Set TRX4M052F/R for Scale Crawling by GPM  [TRX4M052F/R]

52mm machined aluminum shock upgrade for TRX4M

This front and rear spring damper set is intended for TRX4M 1/18 crawlers and is constructed from aluminum 6061-T6. Each damper is oil-filled with a sealed cap to help maintain consistent damping on trails, and preload is adjusted at the top spring retainer to alter initial stiffness without changing spring length.

The dampers control oscillation and absorb trail impacts to keep your rig stable over rough ground. They fit front or rear damper mounting positions on compatible TRX4M 1/18 kits shown below, and the kit supplies shock bodies and replacement springs so you can mount them in stock locations and tune performance by changing oil and preload.

For hobbyists seeking a durable metal upgrade to stock plastic shocks on TRX4M 1/18 crawlers, these 52mm aluminum dampers offer a practical route to improved tuning via preload and oil selection.
