Eliminates ticking from Rocker Arm Shaft hitting Plate Bolts
Includes Step-by-Step Installation Instructions*
The rocker arm shafts have a notch in them that the bolt is supposed to butt up against, locking the rocker arm shafts in place. However, the bolt hole is too large, leaving a gap. This gap allows the shaft to rotate and hit the bolt causing a tick~See the picture where the bolts have witness marks from the rocker shaft rotating and tapping the bolts. ~This is what makes the annoying ticking/tapping noise.~The Rocker Lockers eliminate the gap, locking the shaft from turning and striking the bolt, eliminating that annoying tick so many Twin Cam owners experience. The Rocker Lockers also center the rocker plate so that it is always located in the same position eliminating different wear patterns on the rocker arm/valve and a better alignment of the pushrod in the holes. ~The Rocker Lockers are tapered so that they lock themselves in and wedge the bolt/shaft in place.~Drawing shows how the Teflon Centering Tool Makes installation Easy!~Have you tried changing cams, replacing lifters, adjusting pushrods, different oils and still have that annoying ticking? Try the Rocker Lockers, they will eliminate the ticking from the rocker arm shaft. (this is the most annoying of the valve train noise, and is particularly noticeable between 2000-3000 RPM) Please note~Rocker Lockers will not quiet noisy lifters, noisy chains, gears, tensioners or bearings. Rocker lockers keep the shaft from rotating and hitting the Rocker Support Plate bolts.If you ever need to remove the lockers, just use a punch and tap them out, they are usually reusable.~Patent Pending~Fitment: All Twin Cam Engines, including w/ SE Forged Rocker Support Plates.~Check out our other Rocker Lockers for Sportsters. * While Step-by-Step instructions are included, it is recommended to also supplement them with the Service Manual.
