1978-88 GM G-Body Suspension Parts
Coil springs at all four corners give the G-Body a different starting point from many of the classic platforms in POL's catalog. The parts gathered here build outward from that foundation, covering spring and shock changes, front-end rebuilding, rear control arms, sway bars, drop spindles, chassis bracing, air suspension, and a rear coilover conversion for compatible 1978-88 GM applications.
Building Around the G-Body Coil-Spring Layout
The G-Body begins with coil springs at both ends, which gives this collection a different foundation from leaf-spring cars. You can adjust front and rear ride height independently, or bring both ends together with a Stage 2 package that keeps the conventional spring layout intact.
From there, the suspension separates by function. Up front, rebuild kits, ball joints, cross shafts, tie rod sleeves, shocks, and 2-inch drop spindles let you service or lower the existing geometry without forcing a complete redesign.
At the rear, the focus shifts to axle control. Adjustable upper arms, lower control arms, and complete arm sets change how the rear axle is located within the same coil-sprung architecture, while separate sway bars address roll control at either end of the car.
Air ride and rear coilovers break away from that conventional formula entirely. They give G-Body builds a different way to manage ride height and springing, extending the collection from factory-style restoration and lowering into suspension configurations that fundamentally change how the car is supported.

Can I lower a 1978-88 G-Body with coil springs?
Yes. POL lists front and rear G-Body coil springs with selectable height, along with a Stage 2 front-and-rear coil-spring suspension kit. A 2-inch drop spindle provides another method of changing front ride height.
Are rear control arms available for GM G-Body cars?
Yes. The collection includes separate rear lower control arms, adjustable rear upper control arms, and a complete upper-and-lower rear control arm set for 1978-88 G-Body applications.
Can a G-Body be converted to air suspension?
Yes. POL currently lists dedicated front and rear air ride suspension kits for 1978-88 G-Bodies. The rear system includes air springs, shock absorbers, mounting brackets, and installation hardware.
Is a rear coilover conversion available for 1978-88 G-Bodies?
Yes. A dedicated rear coilover shock conversion is currently included in the collection. This creates a different rear suspension configuration from retaining separate conventional rear coil springs and shocks.
Are front suspension rebuild kits available for G-Body cars?
Yes. POL currently lists three 1978-88 Chevy Malibu front suspension rebuild configurations: rubber bushings, polyurethane bushings, and a Super Deluxe polyurethane package. Ball joints and an upper cross shaft assembly are also available separately.
