Product Details
| Part Number: | SFR-05-008 |
| Brand: | Speedfactory Racing |
Take control of your D-Series transmission with the SpeedFactory Upgraded D-Series Transmission Spring. Designed to replace the weak OEM internal spring, this spring is over 600% stronger, giving your shifter a firm, positive feel while returning it to center with authority. By improving shift accuracy and speed, this spring dramatically enhances performance, especially during the infamous 2-3 shift, a common weak point in D-Series transmissions.
This upgraded internal spring is compatible with all D15 and D16 transmissions, making it perfect for a wide range of classic Honda models, including the 1988-2000 Honda Civic, 1993-1997 Honda Del Sol, and 1988-1991 Honda CRX. Whether you are running a stock transmission or building a dogbox racing setup, this spring improves shifting consistency and helps reduce the risk of costly misshifts like the dreaded 2-3-2 or 1-2-1.
Built for performance, the SpeedFactory Racing D-Series Drag Spec Shifter Spring Kit allows the shifter to automatically drop into third gear when pushed forward, giving you confidence and precision while racing or spirited driving. Engineered for durability and reliability, it comes backed by a lifetime warranty against manufacturing defects, so you can race, modify, or daily drive with peace of mind.
