BEARINGS www.TAPERFORMANCE.com TA Performance Products, Inc. 480-922-6807 Order and Tech Line 101 Extreme Duty Race Main Bearing Sets V6 Hi-Performance 3/4 Groove Main Bearing Made from a unique lining bonded to an extra strength steel backing for unparalleled durability. Additional Crush and Eccentricity have been incorporated into the design of these bearings ensuring the best in durability under extreme stress and high RPM. Additional Crush ensures that the bearing is firmly positioned to deter the main journal from spinning the bearing, additional Crush also aids in lowering oil temperature at the bearing surface to prevent the oil from breaking down. The additional Eccentricity gives additional clearance at the parting line to provide the extra clearance needed between the bearing and journal to prevent the bearing from contacting the crankshaft which can happen at higher RPM when the main journals are most likely to distort. The 3/4 Groove Hi-Performance Main Bearing provides the best of both worlds in a main bearing. The 3/4 groove allows for the most efficient oiling to the journals, yet maintains full surface area in the most heavily loaded portion of the bearing. Crankshafts using the 3/4 grooved main bearings will not need to be cross drilled which will save time and money while improving crankshaft strength. Fits All`78-`89 Production (turbo non -turbo), S tage 1, Stage 2 and TA V3800 Series cylinder blocks. Part Nos.

Additional Crush and Eccentricity have been incorporated into the design of these bearings ensuring the best in durability under extreme stress and high RPM. Additional Crush ensures that the bearing is firmly positioned to deter the rod or main journal from spinning the bearing, additional Crush also aids in lowering oil temperature at the bearing surface to prevent the oil from breaking down. The additional Eccentricity gives additional clearance at the parting line to provide the extra clearance needed between the bearing and journal to prevent the bearing from contacting the crankshaft which can happen at higher RPM when the rod or main journals are most likely to distort. Another aspect of the Hi-Performance rod bearings is the chamfer added to the side of the bearing alongside the crankshaft counterweight, which allows for as much surface area as possible. The chamfer will give the clearance needed on performance ground crankshafts that incorporate a radius fillet. Fits WIDE rod journal crankshafts only, does NOT fit production, TA V1627 or TA V1627-3.400 crankshafts. These bearings do fit most aftermarket stroker as well as TA V1627-3.625 crankshafts.
