New JESEl Shaft Rockers for Ultra Pro Billet Small-Block Chevy heads

Big cubic inch small-blocks are gaining favor in a number of race series, and the Ultra Pro billet aluminum cylinder heads for 4.400” and 4.500” bore-center blocks are well suited for these larger displacements. JESEL now offers a Pro Series shaft rocker kit with an integral one-piece stand that bolts on with no modifications. The standard kit has been engineered for 5.825”-long valves with a 1.850” rocker pivot length. The rockers are CNC-machined from a custom blend 7000 series aluminum alloy. They feature standard profiled tails for valve cover clearance, a shot peened finish for increase strength and a cup-style tool steel adjuster all for a $1,500.00 racer net price tag. They are available by part # KPS-418168 for 4.500” bore center blocks, and part # KPS-420169 for 4.400” bore centers.

JESEL can custom build these kits to your specifications including rocker ratios from 1.55” to 1.90” and with intake rocker adjuster offsets of up to .750”. The rocker bodies are available in your choice of standard milled slot, a lightweight MoHawk beam version or an extreme duty solid body.
