Conv Front Spring 5in x 9.5in x 400

The Conv Front Spring 5in x 9.5in x 400 from INTEGRA SHOCKS is a heavy-duty coil spring engineered for front-end suspension upgrades on vehicles requiring increased load capacity and improved ride geometry. This conventional coil spring serves mechanics, off-road enthusiasts, and restoration shops looking to dial in precise spring rates for custom suspension tuning. Whether you're building a lifted truck, lowering a classic car, or reinforcing a daily driver's front suspension, this 400 lb/in rate spring delivers the consistent compression and rebound characteristics necessary for safe, predictable handling.

Manufactured from high-strength steel and finished with a black powder coat for corrosion resistance, the Conv Front Spring features a 5-inch outside diameter and 9.5-inch free length, making it compatible with many OEM and aftermarket suspension systems. The 400 lb/in spring rate indicates this spring provides 400 pounds of resistance per inch of compression—ideal for supporting heavier front-end weights, stiffer damping setups, or when pairing with high-performance shocks. The powder-coat finish protects against rust and road salt, ensuring durability in harsh conditions and extending the lifespan of your suspension assembly compared to bare steel alternatives.

Installers will appreciate that INTEGRA SHOCKS springs integrate seamlessly into conventional front-spring applications across trucks, SUVs, and performance vehicles. Verify mounting diameter and vehicle-specific spring seat compatibility before purchase, as incorrect spring rates can compromise handling and safety. At 5.7 lbs per spring, you'll need to install a matched pair for balanced front-end performance. This coil spring is sold individually, so order two for a complete front suspension upgrade.
