All upper tubular and lower boxed trailing arms utilize polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms feature a spherical ball or rod end assembly on the chassis end to eliminate bushing bind.
This allows the suspension to move smoother for better control, keeping the tires firmly planted on the ground for improved traction and a more predictable handling car.
Lower arms include mounting points for OE style sway bar (applies to GM A- and G-Body), and both styles are powder-coated gloss black for a long-lasting finish.
Rectangular Trailing Arms are made from 0.120" wall cold rolled steel tubing for maximum strength and flex elimination.
These trailing arms include fluted, greasable, graphite/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, offering increased strength over other designs while also providing the added advantage of lighter weight.
Heavy-Duty Adjustable Trailing Arms allow easy rear suspension adjustments for optimum handling and traction.
They can be adjusted without removing the arms from the vehicle by simply loosening the jam nuts and adjusting the pinion angle.
Spherical ball assembly with UHMW bushings allows the rear suspension to move more freely.
Includes graphite/polyurethane differential bushings to replace soft OE differential bushing.
All parts are sold in pairs.
Note: Part #5274 uses polyurethane bushings on both ends.
