BUICK GS – SKYLARK – SPECIAL and LE SABRE 8.2″ REAR END

3.64 RING AND PINION

GOOD NEWS FOR THE BUICK BOYS !! THE 3.42 AND 3.64 GEAR OPTION IS HOPEFULLY COMING BACK – ( ALONG WITH OUR NEW POSI UNIT TO GET IT TO THE GROUND! )   

 ATTENTION !! FABCRAFT’S EXCLUSIVE GEAR SETS FOR THE BUICK 8.2″ REAR ARE NOT CURRENTLY AVAILABLE  — WE MAY PRODUCE THEM AGAIN SOMETIME IN 2020 — DEPENDING ON DEMAND  — SO, IF YOU ARE INTERESTED PLEASE CONTACT US TO BE PUT ON OUR “LIST”

WITH ENOUGH INTEREST FROM THE BUICK FOLKS OUT THERE, WE HOPE TO SEE OUR WAY TO MAKING A RUN OF THEM AGAIN — AND HOPEFULLY IN BOTH OUR  3.42 AND 3.64 RATIOS  

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  Fabcraft’s Custom Posi that will accommodate this set-up.

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  7/16″ RING GEAR BOLTS (SAME AS FORD 9″)– BUICK USES LARGER 27 SPLINE PINION YOKE AS OPPOSED TO CHEVY 8.2″ 25 SPLINE– BUICK 8.2″ USES A HUGE 1.875″ PINION BEARING THAT DWARFS THE FORD 9″ — BUICK USES OVERSIZE BEARING AND CAP ON THE RING GEAR SIDE OF POSI UNIT FOR STRENGTH– BUICK 8.2″ USES THE MECHANIC’S 3R U-JOINT FOR ADDED 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 MORE TOOTH CONTACT AREA THAN THE FORD 9″– BUICK 8.2″ USES AXLES RETAINED WITHOUT USING THE DREADFUL “C” CLIP- ALL CHEVY 10 AND 12 BOLT REARS USE THIS “C” CLIP SYSTEM AND MANY QUARTER PANELS HAVE BEEN DESTROYED FROM THIS POOR DESIGN FAILING.  YES, THIS IS AN 8.2″ RING GEAR SET 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”!  SEE OUR INSTALLATION KITS HERE IN THE STORE AS WELL
