Do you have an annoying Ticking issue on your Harley-Davidson?

It’s most likely due to the gap in the Rocker Arm Support Plate.  There’s a gap between the Bolt and the Rocker Arm Shaft that allows the shaft to move back and forth producing that ticking noise that’s driving you nuts.  The bolt is supposed to secure the shaft but it fails miserably.

DK Custom have created a solution to this issue for Twin Cam, Sportster & BT EVO models.

The video below explains how to align the shaft and install your Rocker Locker.  It has a great before and after comparison that let’s you clearly hear the improvement after the install.

Features & Benefits:-

* Locks the Rocker Arm Shafts

* Centers the Rocker Arm Support Plates

* The Rocker Lockers are tapered so that they lock themselves in and wedge the bolt/shaft in place.

* Eliminates ticking from Rocker Arm Shaft hitting Plate Bolts

Note: Rocker Lockers will not cure noisy lifters, noisy chains, gears, tensioners or bearings. Rocker lockers keep the shaft from rotating and hitting the inner rocker bolts.
