QA1 78-96 GM B-Body Upper Adjustable Trailing Arms

These trailing arms for 78-96 GM B-Bodies offer an immediate suspension upgrade. All upper tubular and lower boxed trailing arms use polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms use a spherical ball or rod end assembly on the chassis end to eliminate bushing bind, allowing the suspension to move smoother for better control. This keeps the tires planted firmly on the ground for improved traction and a more predictable, better handling car. Trailing arms are powder-coated gloss black for a long lasting finish. Boxed Trailing Arms are constructed from 0.120'' wall cold rolled steel tubing for maximum strength and flex elimination. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. Tubular Trailing Arms are constructed from 1-1/4'' diameter, 0.120'' wall steel tubing which offers increased strength over other designs but also has the added advantage of lighter weight. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. Heavy-Duty Adjustable Trailing Arms allow easy rear suspension adjustments for optimum handling and traction. Simply loosen the jam nuts and adjust the pinion angle without removing the arms from the vehicle. They replace soft OE differential bushings with polyurethane differential bushings, and they use a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end to allow the rear suspension to move more freely and eliminate bushing bind. Adjustable Tubular Lower Trailing Arms are offered in both aluminum and steel. These arms are the ultimate in weight savings and adjustability, and they feature QA1's premium self-sealing and self-lubricating X Series (heat treated chromoly steel) or A Series (aircraft aluminum) rod ends. Kits include (2) lower control arms with rod ends and jam nuts.Installation InstructionsThis Part Fits: Year Make Model Submodel 1978-1983 Buick Estate Wagon Base 1978-1981 Buick LeSabre Base 1985 Buick LeSabre Collector's Edition 1978,1982-1985 Buick LeSabre Custom 1985 Buick LeSabre Estate Wagon 1979-1985 Buick LeSabre Limited 1982 Buick LeSabre Limited Edition F/E 1978-1981 Buick LeSabre Sport 1992-1995 Buick Roadmaster Base 1996 Buick Roadmaster Collector's Edition 1991-1995 Buick Roadmaster Estate Wagon 1996 Buick Roadmaster Estate Wagon Collector's Edition 1992-1995 Buick Roadmaster Limited 1996 Buick Roadmaster Limited Collector's Edition 1986-1992 Chevrolet Caprice Base 1978-1996 Chevrolet Caprice Classic 1986-1990 Chevrolet Caprice Classic Brougham 1978,1981-1982 Chevrolet Caprice Classic Estate 1978-1981 Chevrolet Caprice Classic Landau 1993-1994 Chevrolet Caprice Classic LS 1987-1990 Chevrolet Caprice Classic LS Brougham 1991-1993 Chevrolet Caprice Classic LTZ 1979-1980 Chevrolet Caprice Classic Sport 1978-1985 Chevrolet Impala Base 1981-1982 Chevrolet Impala Estate 1978-1979 Chevrolet Impala Landau 1979-1980 Chevrolet Impala Sport 1994-1996 Chevrolet Impala SS 1978-1992 Oldsmobile Custom Cruiser Base 1978-1983 Oldsmobile Delta 88 Base 1980-1981 Oldsmobile Delta 88 Holiday 1978-1985 Oldsmobile Delta 88 Royale 1980-1985 Oldsmobile Delta 88 Royale Brougham 1984-1985 Oldsmobile Delta 88 Royale Brougham LS 1978-1981 Pontiac Bonneville Base 1978-1981 Pontiac Bonneville Brougham 1978-1981 Pontiac Bonneville Safari 1978-1981 Pontiac Catalina Base 1978-1981 Pontiac Catalina Safari 1983-1986 Pontiac Parisienne Base 1983-1986 Pontiac Parisienne Brougham 1987-1989 Pontiac Safari Base
