Dresses up your Engine Bay.

Harland Sharp original series, pedestal mount, Jeep 4.0L Inline 6, roller rockers are designed to be a replacement for the factory rocker that fits under the stock valve cover. Simply remove the factory rockers and rocker stands and replace with your new Harland Sharp roller rockers.
* These non-adjustable rockers are designed to the factory specs. If you change camshafts or machine the heads, you will have to correct your pushrod length. Always check before installing.
* We recommend always checking for head and valve cover clearance and proper lifter preload.

The Red Diecast Valve Cover works well with the Roller Rockers and has the needed clearance.  Some minor grinding of material may be necessary for clearing Head bolts.
