Extreme Duty Race Rod Bearing Sets V8 494 523/528 Stroker Rod Bearing Sets TA Performance now offers the FIRST ever "Extreme Duty" Rod bearing that is designed to add that extra durability and performance needed in the Buick Big Block. Just as with the TA Sportsman Rods these bearings will make High Power build ups easier and more reliable than ever before. Years of TA dedication and persistence have paid off with the release of these new bearings which are currently available in Std.-.001- .001X and .010 under sizes. The Rod bearings are 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 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. The "Extreme Duty" rod bearing will make hi-end engine building much simpler and straight forward by not forcing builders into Chevy rods just to get a better bearing. By using TA's Sportsman Rods and "Extreme Duty" Bearings, you will be able to plug these parts into your combination with out the expensive and time consuming modifications to the crankshaft and rods when transplanting the Chevy rods into the Buick. Using Chevy rods requires the rod journals to be widened and/or the rods to be narrowed which is an expensive task. The Buick Big Block is known for it's great Rod Ratio, which is one of the key reasons that the Buick makes such good power and torque, using the Chevy rod will lessen that key benefit. Part Nos.

Trying to convince major manufacturers to enter into production on performance bearings for engines that haven't been made in 20+ years is no easy task. In 1996TA released the first ever performance cam bearing for the 350-400-430-455 engines with the innovative Grooved design that allowed repositioning of the oil feed hole to the cam journal. The New Millennium saw the birth of the first full grooved cam bearing for the Turbo V6 Buicks. In 2001 TA updated the grooved bearing with the release of the Dual Groove/Dual Feed design. With the success of the Dual Groove/Dual Feed bearing in the V8 Buicks, TA incorporated that technology into the Turbo V6 bearing in the spring of 2002. In late 2002 TA Performance released the first ever "Extreme Duty" Rod Bearings and Main Bearings for the Buick Big Block. The Quest for better bearings is just another way that TA re-invests back into the Buick Community. Performance rod bearings for our 494 523/528 Stroker crankshafts Part Nos.
