Team Associated RC18T Spring Bottom Caps by 3Racing RC18-029/SI  [RC18-029/SI]

Spring bottom caps for RC18T

This 3Racing accessory provides replacement spring bottom caps intended for Team Associated RC18T shock assemblies. Sold as a set of 4 pcs, the parts are intended solely for 1/18-scale RC suspension maintenance and tuning.

Use these caps to secure the lower end of the spring to the shock shaft pocket, reduce lateral spring movement, and keep spring position consistent during setup changes. They serve as a simple replacement part when original caps are worn or lost, and are suitable for routine track maintenance and setup work on touring/truck style RC18T platforms.

Installation is straightforward: remove the shock from the chassis if needed, compress the spring slightly to access the lower seat, slide the cap into place on the spring base and verify the cap seats evenly around the spring seat. Check free travel and rebound after reassembly to confirm correct seating. No special tools are required beyond typical pit tools.
