 This gear option is back - along with a New Posi Unit to get it to the ground

Made from USA forgings the 8620 steel ring gear has been held to the most rigid specifications.  The pinion is made from 8620 billet bar stock and both heat-treated and finish ground to specifications of + or - .0002.  That is 10 times thinner than a human hair!       Each gear set is lapped to its mating gear, all set-up information is etched into the gears and each gear set is serial numbered. 

 DO NOT confuse the standard GM 8.2 gear with the ROBUST Buick 8.2 ring and pinion.  Buick did their homework! 

NOTABLE FEATURES:  Buick 8.2 uses 10 left hand thread 7/16" diameter ring gear bolts (same size as Ford 9") -- Buick 8.2 uses a larger 27 spline pinion yoke as opposed to Chevy 8.2 with 25 spline  -- Buick 8.2 uses a huge 1.875 pinion bearing that even dwarfs the Ford 9 inch   -- Buick 8.2 uses oversize bearing and cap on the ring gear side of posi units for added strength -- Buick 8.2 uses the Mechanics 3R U-joint for reliability -- Buick 8.2 uses a much heavier rear end axle housing for rigidity -- Buick 8.2 uses a much lower pinion center line (hypoid) in relationship to the ring gear providing much more tooth contact area, as did the Ford 9" -- Buick 8.2 uses axles retained WITHOUT using the dreadful "C" clips!  All Chevy 10 and 12 bolt rear ends use this "C" clip system and many quarter panels have been destroyed from this poor design. 

Yes, this is an 8.2 ring gear as are the Chevy and Pontiac, but that is where the similarities end.  THIS is an overlooked, dependable rear axle assembly and needs to be revisited by the "BUICK BOYS"!

IMPORTANT: To utilize our 3.42 Buick gear sets you must use a Factory Series III open carrier or an Original Factory Series III Posi Carrier (Series III  carriers had 3.23 or 3.42 original gear ratios)  OR you can purchase Fabcraft's Custom Auburn Posi that will accommodate this set-up

 Please call for more information and to be sure we get you set up correctly
