The Ultimate Guide to 1979 Malibu Suspension Parts: Replacement & Upgrades

If you own a 1979 Chevrolet Malibu, the suspension is one of the most critical systems to keep in top shape. Whether you're restoring a classic, building a daily driver, or aiming for better handling, understanding the right 79 Malibu suspension parts is essential. This guide covers the key components, what to look for when buying, and how to choose between OEM-style replacements and performance upgrades.

Front Suspension Components for the 79 Malibu

The front suspension on a 1979 Malibu uses a double wishbone (upper and lower control arms) design with coil springs and shock absorbers. Over time, bushings wear, ball joints loosen, and springs sag. Here are the main parts you'll likely need.

Upper and Lower Control Arms

Control arms connect the steering knuckle to the frame. The original stamped steel arms can develop worn ball joints and bushings. You have two options: replace just the bushings and ball joints, or buy complete new control arms. For most DIYers, complete arms save time and ensure proper alignment. Look for arms with pre-installed ball joints and polyurethane or rubber bushings. Polyurethane bushings offer tighter handling but transmit more road noise, while rubber provides a smoother ride.

Coil Springs

Front coil springs support the vehicle's weight and absorb bumps. On a 79 Malibu, springs often sag after decades of use. Replacement springs come in stock height, mild lowering (1-2 inches), or aggressive lower. If you want a factory ride height and load capacity, choose OEM-spec springs. For a sportier look and lower center of gravity, progressive rate or linear rate lowering springs are popular. Be aware that lowering more than 2 inches may require shorter shocks and may affect alignment.

Shock Absorbers

Front shocks dampen spring oscillations. Standard replacement shocks like Monroe or KYB are affordable and adequate for daily driving. For improved performance, gas-charged shocks (e.g., Bilstein, Koni) reduce fade and provide better control. If you lower the car, choose shocks designed for lowered ride height to avoid bottoming out.

Sway Bar and Bushings

The front sway bar (stabilizer bar) reduces body roll during turns. Original bushings are rubber and wear out. Polyurethane sway bar bushings and end links are a cost-effective upgrade that stiffens the front end without much NVH increase. Replacing the bar itself is optional; a thicker aftermarket bar further reduces roll, but can make the ride harsh on rough roads.

Rear Suspension Components for the 79 Malibu

The rear suspension on a 1979 Malibu is a solid axle with leaf springs. This setup is simple but has specific parts that need attention.

Leaf Springs

Leaf springs wear out over time, losing arch and causing a sagging rear. New leaf springs restore ride height and load capacity. Options include standard replacement (same as OEM) or heavy-duty springs for towing or performance. Some aftermarket springs are designed for a slight drop (about 1 inch) but maintain proper spring rate. Always swap both sides.

Rear Shock Absorbers

Rear shocks control axle motion. Like the front, choose standard or performance shocks. For lowered vehicles, shorter shocks prevent the axle from hitting the bump stops. Gas-charged shocks are recommended for the rear as well.

Bushings and Shackles

Spring bushings and shackle bushings wear out, causing clunks and vague handling. Replace them with rubber or polyurethane. Greasable shackles or bushings make future maintenance easier. U-bolts and nuts should be replaced if rusty.

Steering and Linkage Parts

Though not strictly suspension, steering components affect how the car handles.

Pitman and Idler Arms

These arms connect the steering gear to the center link. Worn arms cause sloppy steering. Moog or OEM replacements are good. Heavy-duty versions exist for aggressive driving.

Inner and Outer Tie Rod Ends

Tie rod ends are wear items. Replace in pairs. Quality brands like Moog or AC Delco work well. At the same time, check the center link and adjuster sleeves.

Steering Gearbox

The recirculating ball gearbox can develop play. A rebuild or replacement (such as a quick-ratio unit) sharpens steering response. This is a more involved upgrade but one of the best for handling.

Performance Upgrades vs. Stock Replacement

When choosing 79 Malibu suspension parts, decide your goal.

Stock Replacement

Best for a restoration or daily driver that needs a comfortable ride. Use factory-style rubber bushings, original spring rates, and standard shocks. Parts from AC Delco, Moog, or Raybestos work well. Expect a smooth, quiet ride that handles like a 1970s car.

Handling Upgrade

For canyon carving or autocross, invest in polyurethane bushings, lowering springs, gas shocks, and a thicker sway bar. Replace all ball joints and tie rods with performance-grade parts. Some owners switch to a front coil-over conversion for adjustability, but that's more expensive.

Budget Build

You don't need top-tier parts for a decent daily. Replace worn bushings with rubber, use economy shocks, and keep stock ride height. The car will drive safely without breaking the bank.

Installation Tips and Considerations

• Always replace all rubber bushings at once if the car is high-mileage. It saves alignment costs.
• Use a spring compressor for front coils safely.
• After installation, get a professional alignment. The 79 Malibu has adjustable camber and caster, but often requires shims.
• Torque all fasteners to spec, and re-torque after a few hundred miles.
• Consider upgrading the rear sway bar if you already have front upgrades.

Final Recommendation

For a 1979 Malibu, start with replacing all worn control arm bushings and ball joints (or new control arms). Add gas shocks and fresh springs front and rear. Inspect steering linkage and replace as needed. Polyurethane bushings in the sway bar give a nice improvement without harshness. If you lower, keep it to 1-1.5 inches to maintain ride quality and avoid rubbing. Quality brands like Moog, KYB, and Energy Suspension offer reliable parts. Stick with a complete overhaul rather than piecemeal repairs. This approach will make your 79 Malibu drive like new—or even better.
