Hybrid Racing Transmission Detent Springs for K/B/D/F/H Series

Hybrid Racing Detent Springs – K, B, D, F, H Series Transmissions

This is one of those mods people always say the same thing about: “I wish I did this sooner.” If your Honda manual transmission feels vague, loose, or rubbery, Hybrid Racing detent springs are an easy bolt-on fix that makes a real, immediate difference—without turning your shifter into a workout.

These heavy-duty detent springs increase preload and spring rate in the transmission’s gear selector mechanism, giving your shifts a more defined, confident feel. Instead of the shifter “falling” into gear, you’ll feel it click into place with intention. The result is a crisp, predictable shift that still feels comfortable on the street.

Hybrid Racing detent springs are up to 80% stiffer than factory Honda springs. They tighten up the forward and backward movement of the shifter, while the matching gear selector springs (K Series Transmissions) handle the left-to-right gate motion. Together, they reduce slop in worn transmissions and sharpen engagement in fresh builds. It’s not aggressive or harsh, just cleaner, tighter, and more satisfying.

You’ll notice the difference on your first drive. Daily driving feels more connected, spirited driving feels more precise, and track use benefits from quicker, more deliberate gear changes. This is a popular upgrade for enthusiasts who want better shifter feel without sacrificing street manners.

These transmission detent springs are compatible with Honda B Series, D Series, F Series, H Series, and K Series manual transmissions. Finished in black zinc for corrosion resistance, they’re built to handle long-term street use or repeated hard driving.

If your shifter feel has been bothering you but you don’t want to go overboard, this is the sweet spot. Simple install, noticeable improvement, and one of the most cost-effective Honda manual transmission upgrades you can make.

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.

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