DHM High RPM Valve Spring Set for the 2022+ Honda Grom

$45.00 Regular price $50.00

After years of not locating the ultimate valve spring, we decided to have our own made. These springs can handle 12k+ RPM with any camshaft available and have been designed to not need an inner spring in order to keep valvetrain weight low. Compatible with the stock retainers.

Fits: 2022+ Honda Grom/Monkey

149cc big bore

Big difference, runs strong and pulls hard. Let’s see how long it will last 😁

Good Product

These springs are significantly stiffer than the stock ones and are a necessity if your tune increases your rev limiter any higher than the factory one. They work well and can definitely handle higher rpm just fine.

Service in general

I've been dealing with dhm since i bought my grom and let me tell you something.... parts are quality and service is unmatched. It don't matter how dumb of a question you have, they will answer it and help you understand. If you have issues and reach out, they will help you trouble shoot it and get it right! I can't thank them enough for everything, to include making sure my order was right when i added a component that would work with the rest of my order.

Nice pieces. Slapped them in while I had the head off for stage 3 piston install. Went in smooth. No complaints!
