Harland Sharp Roller Rockers

The ultimate rocker arm for the 6.5L to replace factory stamped steel sets, center rockers on valves, and remove unwanted valvetrain play.

  Key Features: 

• 16 shaft-rocker arms with roller tips
• Quadstar exclusive laser engraved logos and ratio
• Ratio (specify when ordering):
• 1.5:1 Ratio for stock replacement roller rockers
• The factory ratio is 1.5
• 1.6:1 Ratio for slightly increased valve lift
• Valve clearance should be checked on a full build
• You can upgrade to 1.6 without clearance issues in MOST situations.  Assuming the engine is totally stock with no changes, 1.6 rockers will be fine.  
• 1.7:1 Ratio for extreme builds
• Pistons must be modified for valve clearance
• 1.7 has a longer wait/custom order lead time
• Billet spacer kit for alignment
• Shims may need moved around during initial fitment testing to center the rocker arms on the valve tips. This is a normal step for installation.
• Latest revision for a trouble-free installation
• Eliminates need for the factory plastic rocker arm retainers
• Bolts are not included. Factory mounting bolts will be re-used.
