Jesel Pro Series Shaft Rocker Arms KPS-310116-6565

Rely on Jesel Pro Aluminum Series shaft rocker arms to move you into the winner's circle. Their custom blended 7000 Series aluminum alloy allows for an extremely durable and lightweight valvetrain assembly with a tensile strength at 300 degrees to far exceed that of less expense, industry-standard 2024 alloys. Jesel Pro Series rocker arms have profiled rocker tails and clipped-pin nose rollers, and they are shot-peened for increased resistance to fatigue failures. They are offered in standard slot, Mohawk beam, and solid body styles, as well as different ratios individually and in sets.

Features of Jesel Pro Aluminum shaft-mounted rockers:

* Longer rocker arms provide higher rocker ratios
* Proper travel arc geometry
* Enough rocker-to-valve spring clearance to run big race springs
* CNC-machined aluminum rockers are extra rigid to insure true rocker ratio
* Shaft mounting reduces reciprocating mass for high rpm use
* Easier access to valve springs, lash caps, retainers and locks
* Longer valve spring life
