BMW E81 E82 E87 E88 E90 E91 E92 E93 Bilstein B1 Rear Shock Dust Cover Kit 11-270263

Keep your Bilstein B1 rear shocks sealed and clean on E8x and E9x chassis - no guesswork, no fluff.

• Direct-fit dust cover kit for Bilstein B1 rear dampers (not B12/B14/B16 - those need different gaiters)
• Covers E81/E82/E87/E88 1 Series and E90/E91/E92/E93 3 Series - including N54/N55-powered models
• Also fits ALPINA B3 (E92) with Bilstein B1 rear units - not for S- or D3-spec dampers
• Stage 1 fast road or track day builds? This is the small part that stops grit from wrecking your damping consistency
• Not a styling item. Not a show car upgrade. It’s a functional seal - because race car.
