Say goodbye to inconsistent belt tension and unreliable setups with the SpeedFactory Racing D-Series Heavy-Duty Timing Belt Tensioner Spring. Designed specifically for high-performance and racing Honda D-Series engines, this upgraded spring delivers the precision and reliability your build deserves. Compatible with the 1988–2000 Honda Civic, 1988–1991 Honda CRX, and 1993–1997 Honda Del Sol, this is the perfect solution for enthusiasts tired of dealing with weak OEM components.
Crafted from 302 stainless steel, the SpeedFactory D-Series Tensioner Spring is both corrosion-resistant and over 6x stronger than the OEM spring. This added strength ensures optimal belt tension for high-revving engines using heavy-duty timing belts like the Gates Racing Timing Belt. The result? Improved cam timing control, reduced belt deflection, and the elimination of common issues like skipping teeth or excessive wear under extreme conditions.
Where the OEM spring falls short, the SpeedFactory design shines—providing consistent, repeatable tension without the guesswork or risk of over-tightening. Whether you’re running a fully built D16 race engine or a street-driven D15 setup, this spring is race-proven to deliver flawless performance and long-term reliability.
Used in SpeedFactory’s own top-tier engine builds, this spring guarantees reliable, consistent timing belt tension without the need for additional tensioners. It’s the smart upgrade that protects your investment while enhancing performance across the board.
