BMR 2" Front Big-Block Lowering Springs - Red (SP056R) - 1968-1974 X-Body
Refresh your classic muscle car's suspension and eliminate decades of factory spring sag with the Front Performance Lowering Springs (SP056R) from BMR Suspension. Purpose-built for 1968-1974 GM X-Body platforms equipped with a Big-Block engine, these springs deliver an aggressive 2-inch front drop that radically improves your vehicle's stance and centers its weight lower to the ground. Engineered for street performance and pro-touring builds, this kit utilizes a high-rate linear design to substantially flatten out cornering body roll and deliver sharper steering responsiveness without destroying everyday ride comfort.
Every BMR spring is precision-manufactured from high-tensile chrome silicon spring wire and cold-wound on advanced CNC equipment, ensuring perfect uniformity from the left side to the right side. To guarantee a lifetime of sag-free service, BMR compresses each coil solid twice to set its permanent height, stress-relieves them at 750°F, and shot-peens them to eliminate structural surface stresses. Boasting a heavy-duty 620 lb/in linear spring rate, every individual coil is loaded into a computerized factory tester to measure its force profile before receiving a durable red powder coat finish. This thorough manufacturing process allows BMR to back these springs with an industry-leading lifetime warranty against spring sag.
IMPORTANT FITMENT & COMPATIBILITY NOTES:
- Engine Application: Tuned explicitly for Big-Block engine configurations. Using these springs with a lighter Small-Block or LS-swapped setup will result in less than the advertised 2-inch drop.
- Ride Height Variance: Exact front ride height will vary depending on your specific engine accessories and cylinder head material. A Big-Block configuration with factory iron heads and air conditioning will sit lower than an aluminum-headed engine with no A/C.
- Installation: Estimated installation time is approximately 2-3 hours.
