Walk through the pits of any professional racing venue and you would be hard pressed not to find a JESEL Pro Series rocker system controlling the valvetrain. For over 28 years, championship winning racers in virtually every form of racing from NHRA Pro Stock to Sprint Cup rely on JESEL shaft rockers to get them into the winners circle. Used by top engine builders worldwide, JESEL rockers continue to set the standard by which all others are measured.

 

The excellent mechanical properties inherent to our custom blended 7000 Series aluminum alloy allows for the design of an extremely durable and lightweight valvetrain assembly. Tensile strength of our custom blended alloy at 300° far exceeds that of the less expensive, industry standard 2024 alloys. Low moment of inertia along with FEA designed bodies insures that lobe lift is not wasted due to rocker body deflection.

This is a brand new, in the box, complete set of a Jesel 1.70 kit for the Indy Cylinder Head 572 heads. I bought this direct from ICH with the part number of 572-R4-4J, with a "Racer Net" price of $1,748.

 

413-222k

 

I bought this set for a Mopar motor being built with 572 heads — but decided to go with the 1.55 ratio instead. They're still wrapped in foam wrap. It you are building (or someday will build) a Mopar wedge race motor using 572 heads — here's your chance to save $300.
