The Serpent SER402179 bumper shim comes as a matched two-piece steel set developed for X26 installations. These shims sit at bumper mounting points to alter clearance and alignment precisely, without modifying the main chassis structure.
Apply them where small dimensional changes are needed to prevent rubbing, correct asymmetry, or adjust bumper engagement. Steel offers a reliable, low-wear spacer that holds thickness under repeated loads compared with softer alternatives.
For builders working on X26-based electric RC cars, the SER402179 set is a simple, robust way to secure repeatable bumper spacing and predictable contact behavior.
