RBS is proud to present the latest rocker arm set up from Manton to fit Fat head type Hemi cylinder heads. Manton is offering this complete hi-ratio rocker set up in one affordable package with all the latest improvements and upgrades that a racer could ever want for their Hemi engine.

Included are: ten billet 7075 alum. rocker stands set up for pressure fed oiling. Stands have steel bushings pressed into them so a racer can properly torque the stands over and over again without mushing the alum. rocker stand.

Next up are four heat treated 4130 Chromoly steel rocker arm shafts with .250” wall thickness. Each pre-heat treated shaft is prepared in a four axis milling center, then center less ground undersize, hard chromed oversize and finish ground to size. This leaves a hard chrome surface .008” deep, providing excellent wear protection in any application, including use in your daily driven street Hemi.

Manton Fat Head shafts feature a new type of radial oil transfer passage which provides full time oiling to the pushrod and adjusting screw. Without this new oiling feature the stock oiling passage is shut off as soon as the rocker arm starts to open the valve. All of Manton shafts use a threaded plug to seal each end. This eliminates any chance of an oil leak from worn or poor fitting O-rings.

Last but not least eight forged tool steel 1.8 ratio intake and eight 1.7 ratio exhaust rocker arms with .570" diameter roller tips and 7mm roller pins. Rocker arms have weight reduction pockets to reduce weight but not sacrifice strength on high rpm engines with lots of valve spring pressure. Rockers use a 7/16" adjuster with a 3/8" ball and are made from H-13 tool steel then black oxide finish to give the racer the ultimate in strength and durability. Sixteen adjuster with nuts are included with each assm. as well as sixteen springs to hold the rocker arm in place in the rocker shafts.

Rocker arm assm. will fit Fat, Muscle, Total Flow, Noonan and most all other Fat head type Hemi cylinder heads.
