Now have the peace of mind for your LS V8 with our very own, designed in house, Mace Engineering LS trunnion upgrade kit. These trunnion kits replace 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.

Our kits are engineered to provide maximum durability and stiffness in the harshest environments whilst still being super affordable for all enthusiasts. Extra security measures have been taken with the use of extended width trunnions with snap-ring grooves instead of the bearing housings only relying on a press-fit type fixture. You can now rest assured these bearings will hold their ground and truly enjoy the exhilarating feeling your LS V8 delivers.
