RC18T Shock Spring Bottom Caps 4pc - RC18-029/SI by 3Racing  [RC18-029/SI]

RC18T lower spring caps for consistent setups

Precision replacement spring bottom caps supplied as a 4 piece kit for use with Team Associated RC18T lower spring pockets. These parts are intended to help maintain consistent seat location and reduce lateral spring play across setup iterations.

By stabilising the spring at the lower seat, the caps contribute to repeatable suspension geometry and setup tuning. They are a practical service item for racers needing reliable spring retention between runs or during shock rebuilds.

Installation requires slight spring compression to access the lower seat; remove the shock from the chassis if necessary, position the cap on the spring base and ensure uniform seating around the pocket. Verify free travel and rebound after reassembly to confirm correct fitment. Use standard shock service tools for fitting and inspection.
