Mr. Gasket Coil Spring Boosters

Mr. Gasket Coil Spring Boosters deliver a proven, cost-effective solution for raising ride height on coil spring-equipped vehicles — no new springs, no complex suspension overhaul required. Backed by decades of performance heritage and now part of the Holley Performance family, Mr. Gasket engineered these boosters to fit between or atop coil springs, increasing spring height to provide a reliable lift while helping preserve the vehicle's original ride quality and suspension travel.

Key Features:

• Multiple construction options — the product line includes both high-density rubber spacers and aluminum twist-in boosters to suit a variety of applications and preferences
• Increases spring height for improved stance and clearance without requiring the purchase of replacement springs
• High-density rubber variants increase front coil spring height without unduly compromising spring travel or ride quality
• Aluminum twist-in variants provide a secure, interlocking fit between coils for improved weight transfer — ideal for performance-minded applications
• U-shaped groove design on rubber models locks securely onto the coil spring to resist shifting or dislodging during normal driving
• Versatile fitment — designed to accommodate a wide range of coil spring-equipped cars and trucks across many makes and models
• Does not affect vehicle emissions systems — compatible with both emissions-controlled and non-emissions-controlled vehicles
• Straightforward installation requiring only basic tools; no cutting, welding, or permanent vehicle modification

Installation Note: The coil spring must be removed from the vehicle for proper installation. Professional installation is recommended to ensure safe and correct fitment.

Whether you're correcting a sagging stance, leveling the vehicle for larger tires, or simply restoring lost ride height, Mr. Gasket Coil Spring Boosters offer a trusted, bolt-on approach with the quality and reliability that has made Mr. Gasket a respected name in performance and restoration components since the 1960s.
