Cummins 12V Roller Rocker Arm Kit
Add durability and performance to your valve train with No Limit’s roller rocker kit for 12v Cummins engines.
Corrected Rocker Arm Geometry reduces the amount the roller tip
travels across the valve tip, and translates the camshaft motion more
accurately. This also reduces valve tip and valve guide wear.
Bushed aluminum rocker arm bodies provide light wieght performance with wear protection.
Bushings are burnished for ulitmate roundness, and strength.
Increased ratios to add valve lift. 1.7 , 1.75, and 1.8. Custom ratios are available upon request.
Pressurized oiling to the rocker arm shaft, and pushrod
.

One Piece Billet Aluminum Valve cover with oring seal, and 2 fill or breather holes.
Pressurized oiling spray bar to oil the roller tip and valve springs. Spray bar includes metering
jets to put the right amount oil were it counts, with out overloading the valve train with too much oil.
Precision V Block style stand with a snap tight shaft fitment. The
shaft and stand provide multiple clamping points increaseing shaft and
stand rigidity. This reduces shaft deflection, and negative harmonics in
rocker arm system. Produces even more accurate camshaft
translation, and valvetrain durability.
4340 coated and hardened rocker shaft for high durability, and
