Rocker Arm Adjusting Nuts All COMP Cams Rocker Arm Adjusting Nuts are designed for the ultimate in strength and locking force. The stud girdle polylocks are precision ground for minimum runout and tapered for extra strength in the locking area. The special alloys in the polylocks ensure quality and strength not found in any other competitive products.
Rocker Arm Adjusting Kits Many of the popular engine families utilize a positive stop type of rocker arm attachment which does not allow for any adjustment, and consequently there is no consideration for different cam sizes or other modifications to the engine block and heads. For that reason, COMP Cams has designed a kit to convert this setup to a fully adjustable valve train. On the 302-351W Fords, simply remove the standard adjusting nut, slip the spacer over the stud, install the new nut and adjust the valves as necessary. On the Mark V & VI Big Block Chevrolet engines, replace the screw-in studs with those provided, slip the spacer insert through the rocker arm ball, and adjust with the new adjusting nut. These kits are a simple, easy and inexpensive alternative to give the flexibility of an adjustable valve train.
