If your balancer is starting to wobble and is on its way out, Powerbond has a replacement available to suit your needs. From a standard replacement to a performance replacement for those that race their car or just want that little bit extra from their engine.

Now have the peace of mind for your LS V8 with Crow Cams LS trunnion and bush kit. This trunnion kit replaces the factory LS rocker internals that are prone to failure when exposed to extended levels of high rpm, high valve spring pressures and amplified rotation from high-lift camshafts. The OE needle bearing housings can begin to separate from the rocker arm when exposed to these conditions, gradually spitting out all the needle rollers which in turn results in a catastrophe.

Crow Cams LS trunnion and bush kits are engineered to provide maximum durability and stiffness in the harshest environments whilst still being affordable for all enthusiasts. You can now rest assured these bush/plain bearings will hold their ground and truly enjoy the exhilarating feeling your LS V8 delivers.
