ROCKER BOX KIT ALL BIG DOGS S&S NEW 4-1/8 BORES ONLY

• Produced using the die-casting manufacturing process and then machined with computer controlled equipment. S&S die cast rocker covers for all Big Dog engines include Viton® o-ring style cover seals for leak-free operation. Our proven two-piece design makes installation simple.

   FEATURES AND BENEFITS

• Special rocker arm supports are included
• S&S rocker covers are finished with show-quality chrome
• Installation on stock and most comparable sized engines can be performed without removing the engine from the frame
• Clearanced to permit valve lifts up to .640" using S&S valve spring packages and stock rocker arms or S&S roller rocker arms
• S&S rocker covers accept valve springs up to 1.660" O.D. without modification
• Exclusive one way valve built into the rocker cover gasket to control oil carry over

Notes:

If using valve spring packages with taller than stock installed height, some minor clearancing may be required. Cylinder heads must be set up correctly for high lift cams, and it remains the builder’s responsibility to confirm all clearances. In most instances, only minor clearancing is required to use S&S rocker covers with valve springs larger than 1.660” O.D.
