Fits the old style non "hemi" head Harbor Freight Predator. The ARC 6058 sidecover features side by side dual ball bearings that support the crank and gives it another fulcrum point to help eliminate any crankshaft flexing. It has an integral o-ring along the perimeter in it's machined groove that guarantees a good seal. 4 solid pin receptacles mate with solid dowels to increase mating shear strength. Bronze bushing(with ARC's adavanced oil system) support for camshaft main increases strength and minimizes potential for wear. It has 2 venting holes at the top with 1/8" NPT Plugs. It also has 2 oil fill ports with billet ARC aluminum hand tighten plugs. Another useful feature is the threaded holes over the side dowel -pins so that small bolts (included) can be used to push the side cover for easy removal.
* Includes: Bearings, Seal, Gasket, O-Ring, Plugs and caps and installation hardware.
* Important * Due to variations in clone blocks, you may find that the side cover is not quite lining up with all four dowell pins. Try removing the bottom dowell pin if you encounter difficulty. Contact our tech department if you have any problems.
