Coil Springs Rear 5.5in Drop 67-72 GM C10 Truck

The Detroit Speed Engineering Coil Springs Rear 5.5in Drop for 1967–72 GM C10 trucks delivers the aggressive stance that separates a stock hauler from a purpose-built hot rod or lowrider. Whether you're building a vintage truck for shows, street cruising, or functional performance, these rear coil springs provide the foundation for a proportional, track-ready suspension geometry. Designed specifically for the second-generation C10 platform, this pair addresses the factory ride height while maintaining structural integrity and long-term durability.

Manufactured from high-quality steel and finished with black powder coat for corrosion resistance, these coil springs are engineered to handle the 5.5-inch vertical drop without sacrificing spring rate or load-carrying capacity. The powder-coat finish protects against road salt and moisture—critical for preserving suspension geometry over years of driving. Each spring maintains proper preload characteristics, ensuring predictable handling and consistent ride height across varying load conditions. The 16.4-pound weight per pair reflects the robust construction necessary for reliable performance on vintage C10 frames, which demand stronger spring rates than modern independent suspensions.

Mechanics and builders installing these springs on 1967–72 C10 trucks will appreciate the direct fitment and compatibility with OEM mounting points—no custom fabrication required for basic installation. Pair these rear coil springs with complementary front suspension components to achieve a balanced stance and proper weight distribution. Installation typically involves removing the rear axle housing, unloading existing springs, and securing the new pair to restore the desired ride height. This kit is essential for anyone serious about authentically lowering a classic GM C10 while maintaining reliability and driveability on both show grounds and public roads.
