Triple S Coilover Springs – ID: 70mm / Length: 180mm

Triple S Coilover Springs in 70mm ID × 180mm length are a direct drop-in upgrade for virtually any aftermarket coilover kit — BC Racing, Yellow Speed, Fortune Auto, KSport, and more. Built from proprietary TS2000 alloy (2,000 MPa tensile strength) instead of the industry-standard SAE9254 (1,800 MPa), they deliver more usable stroke, more consistent spring rates, and up to 20% lighter weight than the factory springs that came with your coilovers.

Pick your preferred spring rate from the drop-down to fine-tune your setup — whether you want more compliance for daily driving, tighter control for track days, or a firmer rate to pair with sticky tires. Because TS2000 is rated for a higher tensile load, Triple S can wind a taller spring in the same active length, giving you more stroke before coil bind and a more linear response through the full range of damper travel. Each spring is finished in a durable green powder coat and backed by a 1-year manufacturer defect warranty.

Triple S is manufactured by Yang Min Enterprise, an OEM coil-spring supplier with over 50 years of production experience and ISO 9001, IATF 16949, and ISO 14001 certifications. Every spring is cold-forged and pre-set to eliminate sag, so the rate you order on day one is the rate you keep after thousands of miles.

Sold in pairs (2 springs total).
