TRF421X Piston 4 Holes 4x1,2 BLK, model part

TRF421X Piston 4 Holes 4x1,2 BLK is a dedicated model spare part for suspension servicing and setup work. The pack contains 4 black pistons, giving a consistent set for replacing worn internals or preparing matching damper builds where equal specification across all corners matters. The 4-hole design in a 4x1,2 configuration defines how shock oil passes through the piston during compression and rebound. That makes this part relevant when damping response needs to be kept consistent after maintenance or changed with a specific piston layout already in mind. The exact TRF421X naming also helps separate this version from other piston types during parts storage and workshop preparation. As a compact tuning and replacement component, it fits naturally into routine rebuilds, damper refreshes and planned setup changes where the internal shock specification is chosen deliberately rather than left mixed. On the bench, the set suits organised rebuild sessions where all 4 dampers are being refreshed together. It also supports trackside maintenance when a matching piston set is needed to return a compatible chassis to an even suspension setup after wear or damage.
