Choosing the Right Volvo 122 Suspension Parts for Your Restoration

Restoring a Volvo 122 (also known as the Amazon) means getting the suspension right. Whether you’re chasing factory-correct handling or a mild upgrade for modern roads, the right parts make all the difference. This guide covers the key suspension components for the Volvo 122, what to look for, and how to choose parts that suit your driving style and budget.

Understanding the Volvo 122 Suspension Layout

The Volvo 122 uses a front independent suspension with coil springs and upper and lower control arms, plus a solid rear axle with leaf springs. This design is robust but can feel dated by modern standards. Common wear items include bushings, ball joints, shocks, and springs. Many parts are still available new or as high-quality reproductions, but some require careful sourcing.

Front Suspension Components

Coil Springs

Stock front springs on the 122 are progressive rate, providing a comfortable ride. Over time, they sag, leading to lower ride height and poor handling. Replacement springs are available in standard height and lowering options. If you want better cornering, consider stiffer springs from IPD, Kilen, or Lesjöfors. For a stock restoration, use OEM-spec springs from aftermarket suppliers.

Shock Absorbers

Original shocks were hydraulic, but modern gas shocks offer improved damping and longevity. Bilstein B6 and B4 are popular upgrades, as are KYB Gas-A-Just. For a factory look, you can find reproduction shocks from companies like Stahlbus or use NOS (new old stock) parts. Make sure to match shocks with spring rate—a stiffer spring needs a firmer shock.

Control Arms and Bushings

The control arms themselves rarely fail, but the bushings wear out. Polyurethane bushings from SuperPro or Powerflex reduce flex and improve steering response. However, they transmit more road noise and vibration. Rubber bushings from Volvo or aftermarket brands like Meyle offer a quieter ride. Replace ball joints and tie rod ends at the same time.

Sway Bars (Anti-Roll Bars)

Front and rear sway bars improve handling and reduce body roll. Stock bars are thin (around 19mm front, 16mm rear). Upgraded bars from IPD (22mm front, 22mm rear) are a popular upgrade. Rear sway bars were optional on some models; aftermarket kits include mounting hardware. Installing a rear bar transforms the car’s cornering character.

Rear Suspension Components

Leaf Springs

The rear axle is supported by multi-leaf springs. They sag over time, leading to a lower tail and poor load capacity. You can buy new leaf springs from Eaton Detroit Spring or Alcan Spring. For a lower stance, choose a 1–2 inch drop. For heavy loads or towing, add an extra leaf. Also consider polyurethane bushings for the spring eyes and shackles.

Rear Shock Absorbers

Gas shocks like Bilstein B6 for the rear improve control. Some cars have shock mounts that are prone to rust—inspect and repair before installation.

Steering and Alignment Parts

While not strictly suspension, steering components affect handling. Replace worn steering gearbox, idler arm, and tie rods. Aftermarket steering dampeners are available from IPD. After any suspension work, get a professional alignment. Camber and caster are not adjustable on the front; use offset bushings or adjustable strut rods if needed.

Choosing Between Stock and Performance

Decide early if you want originality or improved handling. Stock setup is fine for gentle cruising and shows. Performance upgrades make the car more enjoyable on twisty roads but can compromise ride comfort. A common middle ground: stock springs with polyurethane bushings and Bilstein shocks. This reduces flex without harshness.

Recommended Brands

• Springs: Lesjöfors (standard height), IPD (lowering/stiffer), Kilen (OEM style)
• Shocks: Bilstein B6 (sport/gas), KYB Gas-A-Just (affordable), Sachs (OEM quality)
• Bushings: SuperPro (polyurethane), Powerflex (polyurethane), Meyle (rubber)
• Sway bars: IPD
• Leaf springs: Eaton Detroit Spring (custom made)

Installation Considerations

Suspension work on a Volvo 122 is straightforward but requires patience. Rusted bolts and seized bushings are common. Have a torch, penetrating oil, and a ball joint separator ready. Replace all hardware with new Grade 8 bolts. Torque specifications are easy to find in factory manuals. If you’re not comfortable, a shop that specializes in vintage Volvos can help.

Final Recommendation

For a well-balanced restoration: start with new Lesjöfors stock-height springs, Bilstein B4 shocks, polyurethane bushings in key locations (control arms, sway bar), and an IPD sway bar set. Replace all ball joints, tie rods, and steering components. This combination will give you a responsive, comfortable ride that’s safer than original and still looks correct. Avoid cheap parts—quality suspension components last decades on a low-mileage classic.

Take your time, source from reputable suppliers, and enjoy the transformed driving experience of your Volvo 122.
