Big thanks to David from HeadGames Motorworks and his team for stopping by Jesel Valvetrain and capturing this behind-the-scenes look inside our shop.

From Keyway Roller Lifters to Camshaft Belt Drives, this video shows the precision, machining, and craftsmanship behind components built to survive where most fail.

For decades, Jesel has been pushing valvetrain technology to the li...

Old School Rules Still Apply.

First released in 1990, JESEL Premium Stud Rockers were originally developed for NASCAR teams back before shaft rocker systems were legal. 🏁

Same old-school purpose.
Modern JESEL engineering.
No stud girdles. No pushrod guide plates. No shortcuts.

Shot-Peened Finish
Dual 3/8” Wide Bearings
External Thrust Washers

Still running blue rockers?

Those blue JESEL shaft rockers are from the late 1970s. While they helped set the standard back then, rocker arm technology has come a long way.

Better materials. Better geometry. Better stiffness. Better control.

Over the years, we’ve seen plenty of companies try to copy the JESEL rocker arm concept. But looking the part and performing like the original are two very different things.

The valvetrain doesn’t forgive weak links, and today’s engines demand more than yesterday’s technology, or a mediocre copy of it.

For over 45 years, JESEL has continued to push rocker arm development forward, from the early aftermarket shaft systems to the modern designs racers depend on today.

Old school JESEL started it.
Others tried to follow it.
JESEL continues to lead it. 🇺🇸
