Installing performance suspension on your A-Body might seem like an overwhelming task, but Chassisworks has come up with a performance suspension system that is a direct replacement for the stock components. So if you’re looking for a direct-replacement suspension upgrade for your 1967-72 GM A-Body car, than Chassisworks’ new g-Bar canted-4-bar rear suspension conversion is definitely worth a look.

Official Release:

g-Bar Canted-4-Bar Rear Suspension for 1967-72 GM A-Bodies

Chassisworks new g-Bar/g-Link system is a direct-replacement canted-4-bar rear suspension conversion for ’67-72 GM A-Bodies with OEM 10- or 12-bolt housings, or Chassisworks’ FAB9 Ford 9” conversion housing. The system can be configured for different levels of performance including street friendly urethane-bushed g-Bar arms, more handling oriented pivot-ball g-Link arms, or the rod end equipped 4130 ProPower arms suitable for professional levels of drag racing. VariShock single- or double-adjustable coil-overs or air-springs can be selected further increasing the range of performance applications for which the system can be configured. Two different styles of shock mounts are available. The direct bolt-on set locates off existing vehicle features and only requires a few additional drilled holes to secure the mounts. To accommodate extremely wide rear tires, a weld-on set is available which utilizes a tubular upper crossmember and replacement axle brackets. The weld-on lower brackets provide the added feature of multiple lower-arm mounting holes to adjust the rear suspension’s instant center geometry. The weld-on bracket option is only available with g-Link or ProPower arms. Both styles of lower axle brackets incorporate a multiple-position billet shock mount that allows ride-height adjustment without sacrificing valuable shock travel. Optional components include: adjustable-rate tubular rear anti-roll bar, aluminum rearend girdle, and control arm support brace (not shown).
