The SpeedFactory HD Detent Spring Kit is a set of two upgraded coil spring (Except K-Series applications, 3 single coil springs) that greatly increases the positive ratcheting feel of your transmission.
These spring kits are suitable for use in any car, street or track and are ideal for anyone desiring improved shifting feel.
Greatly improved tactile feedback/feel of each shift also helps ensure that the fork is fully in the desired gear position, and that it stays there.
Simple installation takes just minutes in the car:
