Take full control of your suspension setup with our premium 8.75 inch coilover springs, designed for enthusiasts who demand both precision and performance. These black powder-coated springs come in 8k, 10k, 12k, and 14k spring rates, offering flexibility for a wide range of street and track applications.
Each spring is manufactured from high-tensile steel to deliver long-lasting durability, consistent rate performance, and resistance to sag or fatigue under high stress. The 2.5-inch (64mm) inner diameter is a standard size compatible with many coilover systems, including Function and Form Type 1, Type 2, Type 3, and Type 4 coilovers, as well as other brands that accept universal 2.5” ID springs.
Whether you’re fine-tuning for daily comfort, weekend canyon carving, or competitive racing, these 8.75 inch coilover springs allow you to dial in your suspension with precision. The increased length over typical 7″ or 8″ springs provides additional travel, making them ideal for vehicles needing more compression without bottoming out.
Select the 8k spring rate for a supple ride that maintains control without sacrificing comfort—perfect for daily drivers and lightly tuned setups. Opt for the 10k or 12k rates to gain improved cornering stability and flatter handling characteristics. The 14k spring offers the highest stiffness in this range, ideal for aggressive setups on the track or vehicles with added aero or weight transfer concerns.
These springs are sold in pairs (2) and ship preload-ready, saving time during installation. The durable black finish adds corrosion protection while maintaining a clean, understated look suitable for show builds and performance applications alike.
Whether you’re building a race car, daily driver, or weekend cruiser, the 8.75 inch coilover springs deliver the ride quality, control, and adjustability you need to hit your goals. Backed by Function and Form’s reputation for performance suspension engineering, these springs are a trusted choice for builders who want quality and results.
