Jesel Inc

If you want the very best valvetrain parts this is the place to get it from! The machining of my LS7/ Mast Black Label Pro Steel rockers and billet mounts is impeccable. The rocker assembly seems to be done in a clean room, zero debris or machining dust anywhere. The quality is amazing. The price point is not for everyone out there but again how many people get this part wrong and destroy an engine? Get your valvetrain geometry wrong and you built a nice grenade. They have different rocker systems that work for a ton of applications, just know that you are getting the very best in USA made quality and craftsmanship. Zero machining errors and excellent QC on materials and final product before you receive it. Love the packing and all the brochures and that these are proudly made in the USA! Rob was my salesman from the get go and was very nice, patient and helpful in getting the correct kit for my Mast heads. The turnaround time was way faster than quoted, yet another way to exceed customers expectations despite supply chain issues other manufacturers are experiencing. I will definitely shop again and only get my valvetrain parts from Jesel. Nobody else comes close to these guys, go see what the pros are using running 3500hp TT builds and you will see Jesel rockers under that valve cover guaranteed. Thank you Jesel team!

Great people work there
