FCM bump stops and dust boots for Koni

The original! A must-have with any shock/spring upgrade. We've been talking about suspension travel and bump stops before it was fashionable. Our kits are an integrated package (not just a part) and are designed for your particular setup, including washers and spacers (when needed, to limit travel and protect your shocks). Anyone can sell a part (at double the cost), we provide a solution.

Why use FCM? While OE 99-05 stops are an improvement over the 90-97 rubber stops, they are a lower grade of MCU and are prone to disintegrating. Here's a quick Youtube video showing worn OE rear stops.. Don't let this happen to you. We use the highest quality MCU (*micro*-cellular polyurethane) available. This safely maximizes suspension travel, increases comfort and enhances your driving enjoyment at the limit. Even if you only commute, you'll appreciate how well these kits work - at less than OE prices!


Each kit fits (4) corners
  • Step 1 - Choose bump stop type (Application guide)
  • Step 2 - Re-use your OE dust boots or purchase new boots if needed (we recommend Summit Racing - Pro Comp p/n 12127 black, 12128 red).
  • Step 3 - Purchase Comfort, Sport, or Track bump stop kits from 5X Racing or Good-Win Racing or Moss Motors
  • NOTE: Spacers are not required with 99-05 Koni shocks
