High tensile chrome silicon steel Function Performance Springs (FPS) withstand shock loads and high stress.

Refine your suspension setup with premium coilover springs 10K 2.75 inch inner diameter, built for those who demand better handling and suspension response from their vehicle. Designed with a 2.75-inch (70mm) inner diameter and 7-inch height, these high-quality springs are ideal for drivers looking to improve their vehicle’s cornering capability, ride stiffness, and overall performance.

Perfectly suited for Function and Form Type 1, Type 2, Type 3, and Type 4 coilover systems, these 10K coilover springs are sold in pairs (2) and are intended to replace or upgrade your current spring configuration. Whether you’re setting up a track car, an aggressively tuned street build, or simply refreshing a worn-out suspension system, these springs offer a reliable and predictable upgrade.

The 10K spring rate is tailored for performance driving, offering increased resistance to body roll and brake dive. It delivers better feedback through turns and improved weight transfer under acceleration and braking, without being overly harsh for daily driving. This makes it a popular choice for drivers who want a sportier ride with added confidence at higher speeds or during spirited driving.

Constructed from high-tensile spring steel, these springs are engineered to handle demanding conditions and repeated cycles without sagging or fatigue. The robust powder-coated finish ensures long-term protection against rust and corrosion, making them suitable for use in all climates.

The 2.75-inch inner diameter provides a slightly larger fitment profile, helping ensure better compatibility with wider spring perches or setups that require increased clearance. Combined with the 7-inch height, these springs are optimized for use with full-bodied coilovers that feature threaded shock bodies, allowing for easy preload adjustment and fine-tuning of ride height without affecting damper stroke.

With their responsive compression characteristics and consistent performance, coilover springs 10K 2.75 inch ID are the go-to choice for tuners and racers who want to elevate their suspension system with springs that offer control, reliability, and aggressive handling—without sacrificing too much comfort.
