The shifter is quality made and has crisp, firm shifts. Definitely worth the price!

Had an aftermarket shifter in my car already, but replaced it with this acuity one, complete night-and-day difference. Best decision I could’ve made was getting this shifter out of all of them.

It's great. Not a lot to say other than that. I'd purchase again. Nice, crisp shifts. No more 3rd gear 'crunch'. More confident shifts.

Great product. Would buy for any car. Shift is dead on, zero movement. Super fast shipping..

The products Acuity makes are top notch. Fit and finish is amazing, feels great when shifting. Hands down the nicest shifter I've ever used.
