What Our Customers Say

Race-Proven. Community Approved.

“Bought a clutch and flywheel from Josh and couldn’t be happier. From helping me pick what clutch I needed for my application, he recommended exactly what I needed. Shipping was on time, part came in perfect condition — the guy even helped me with instructions how to do it.”

— Will Toynton, Facebook review

“Josh and KDM Tuners are fantastic to deal with. Always quick in answering my questions no matter how big or small. My last purchase was a throttle body spacer for my VT which was awesome. Quick shipping as well. These guys are my go to!”
