UMI Performance 1in Solid 4140 CrMo Rear Sway Bar for Select 1964-1972 GM A-Body (4034-R)

Fits select 1964-1972 GM A-Body vehicles, including Chevrolet Chevelle, El Camino, and Monte Carlo; Pontiac GTO, LeMans, and Grand Prix; Oldsmobile 442 and Cutlass; and Buick Skylark and GS.

Improve the handling and stability of your classic GM A-Body with this heavy-duty 1-inch solid rear sway bar. Engineered to significantly reduce body roll and understeer, this bar provides a more balanced suspension feel during aggressive cornering. Beyond its handling benefits, the solid construction helps maintain a level chassis for straighter, more consistent launches at the drag strip.

The UMI Performance 4034-R is manufactured from 1-inch solid 4140 Chrome Moly (CrMo) steel. Each bar is hot-formed and heat-treated as a single piece to ensure maximum structural integrity and "memory" retention. Unlike cold-bent alternatives, this process ensures the bar maintains its shape and spring rate even under heavy, repeated loading.
