Hybrid Racing Heavy Duty Detent Spring Kit

Hybrid Racing Detent Springs – K, B, D, F, H Series Transmissions (Black Zinc)

If you want your Honda manual transmission to feel crisp, tight, and predictable, Hybrid Racing detent springs are one of the easiest upgrades you can bolt on. These heavy-duty detent springs increase preload and spring rate on the gear selector mechanism, giving your B Series, D Series, H Series, F Series, or K Series transmission a sharper, more positive shift. If your shifter feels loose or vague, these black zinc detent springs put the feedback back in your hand instead of leaving it buried in the case.

Hybrid Racing transmission springs are up to 80% stiffer than the factory Honda pieces, so the selector locks into each gear with more authority instead of “falling” into place. These manual transmission detent springs affect the forward and backward motion of the shifter, while our heavy-duty gear selector springs handle the left and right gate movement. Together, they clean up slop in worn gearboxes and tighten up engagement on fresh builds. You’ll feel the difference on the first drive—whether you’re dailying the car, banging gears at the track, or abusing them in a dedicated race car detent springs setup. We run these exact springs in our own street and race cars.

Compatibility

These Hybrid Racing detent springs fit most Honda manual transmissions. How many springs you’ll use depends on the gearbox:

• Uses all 3 springs: Honda B Series AWD, Honda K Series FWD and AWD, Honda D Series 1996–2000, Honda GK5 Fit
• Uses 2 of the 3 springs: Honda B Series FWD, Honda F Series F20 and F22A, Honda H Series

Some units, like many B Series boxes, also use an internal detent spring for the 5th/reverse gate. Swapping that one means opening the case, so plan on doing it during a rebuild or synchro refresh.

Not Compatible With

• 2016+ Honda Civic K Series or L Series transmissions
• Honda J Series V6 transmissions
• Honda Fit and CR-Z L Series transmissions
• Honda Civic 2006–2015 R Series
