The Hybrid Racing Heavy-Duty Transmission Detent Springs provide an essential upgrade for your transmission, offering increased preload and a stiffer spring rate compared to factory components. These upgrades contribute to a more precise transmission gear selector function. By replacing the softer OEM springs, your gear engagements will become noticeably sharper and more defined.

Rigorously Tested for Optimal Performance

Over the past year, these springs have been thoroughly tested in a Civic Type R, subjected to the rigors of both street driving and race track conditions. For Civic Type R owners, the installation of these springs translates into a more responsive shifter with quicker centering and more distinct gear engagements.

Dramatic Improvement in Civic Sport and Si Models

Civic Sport and Civic Si models will experience a profound improvement in shifter feel. The left/right (L/R) movement force of the springs is increased by over 100%, while the front/back (F/B) movements are over 25% stiffer. This enhancement leads to a crisper and more satisfying gear engagement.

Specific Stiffness Enhancements for Civic Models

• For the 2017-2021 Civic Type R FK8 K20C, the springs are 18% stiffer in the F/B direction and 97% stiffer in the L/R direction compared to OEM.
• For the 2017-2021 Civic MT (Sport / Si) L15 models, the springs are 2% stiffer in the F/B direction and 124% stiffer in the L/R direction compared to OEM.

Installation and Torque Specifications

When installing these springs in a Honda K-Series transmission, ensure the detent bolts are torqued to 16 lbf-ft (22 N-m / 2.2 kgf-m) to guarantee optimal performance and fit.
