Product Details
Powerglide™ Steady Roll Tappet by JIMS®. It is no secret to us at JIMS® (and to top engine builders) that performance V-Twin engines require more valve lift than stock designs. This increases the load on the tappet roller, which can lead to failure. Tappet roller failure is a catastrophic and expensive failure. Broken needle rollers allow the tappet roller to deform, causing cam lobe damage. Pieces of the hard rollers, as well as debris from the cam can easily contaminate other parts, such as cam plates, bearings, oil pumps, and other tappets ultimately resulting in a complete rebuild.

To remedy this, JIMS have replaced the needle rollers with a special bronze alloy bushing, resulting in increased reliability and longevity. No longer do you need to worry about needle rollers and debris damaging the engine in the event of a failure. In addition to this, JIMS has invested in new machinery that controls the hydraulic unit fitment tolerance within .00015". This new failsafe design means that, even if the bushing wears out, it will be retained in the tappet assembly.
