ARRMA ARA-2642 Silicone Bump Stop 3x6x8mm

These ARRMA silicone bump stops fit vehicles with 3mm shock shafts and are designed to reduce shock bottoming under heavy compression. The bump stop rides on the shock shaft and cushions the final few millimeters of travel, turning a metal-on-metal bottom-out into a progressive, damped stop.

Molded from resilient silicone, the stops compress predictably and spring back run after run without taking a permanent set. That protection matters most on big landings and square-edge hits — the impacts that would otherwise slam the shock piston into the seal cap, stressing shafts, pistons, and shock ends.

Bump stops are also a quiet tuning tool: they progressively firm up the end of the stroke, letting you run a plusher spring and oil setup without bottoming harshly on the biggest hits.

Fitment is ARRMA vehicles with 3mm shock shafts — confirm against your model's exploded parts diagram. The package includes four 3x6x8mm silicone bump stops.
