This protective kit includes the dust cover (bellows) that shields the strut piston rod from contaminants and an integrated bump stop that prevents metal-to-metal contact at full suspension compression. Damaged covers allow dirt to destroy the strut seal, while a missing bump stop can cause severe suspension damage. Our kits feature durable, flexible bellows and energy-absorbing bump stops. They provide essential protection for the shock absorber's internal seals, extend its service life, and prevent catastrophic suspension bottoming-out, ensuring long-term reliability and safety.
