The Complete Guide to Studebaker Suspension Parts for Restoration and Repair

Restoring or maintaining a classic Studebaker requires attention to every system, and the suspension is no exception. Whether you own a Commander, Champion, Avanti, or Hawk, the right suspension parts are crucial for ride quality, handling, and safety. This guide covers the common components, sourcing options, and practical tips for getting your Studebaker back on the road.

Why Suspension Matters on Your Studebaker

The suspension system supports the vehicle's weight, absorbs road shocks, and keeps tires in contact with the pavement. On a vintage Studebaker, worn parts can lead to excessive bounce, poor steering response, uneven tire wear, and even dangerous handling. Many original suspension components are decades old and may be cracked, sagging, or rusted. Replacing them restores the driving experience and makes the car more enjoyable and safer.

Common Studebaker Suspension Issues

Over time, several problems emerge:

• Sagging coils or leaf springs – Leads to a lower ride height and poor handling.
• Worn bushings – Creates clunking noises and vague steering.
• Leaking or weak shock absorbers – Causes excessive bouncing and poor damping.
• Seized or rusted adjusters – Common on torsion bar setups (used in some models).
• Broken sway bar links – Reduces roll resistance.

Identifying these issues early can prevent further damage to other components.

Key Suspension Components for Studebakers

Coil Springs and Leaf Springs

Studebaker used both coil springs (on many cars from the 1950s onward) and leaf springs (on earlier models and some trucks). Coil springs are found on the front of many models, while rear suspensions often use leaf springs. Factors to consider:

• Spring rate – Stiffer springs improve handling but reduce ride comfort. Softer springs do the opposite.
• Height – Original ride height should be maintained unless you want a lowered look.
• Quality – Look for springs made from high-quality steel with proper heat treatment. Some aftermarket suppliers offer progressive-rate springs for a better balance.

Shock Absorbers

Modern gas-charged shocks are a great upgrade for Studebakers. They provide consistent damping and resist fade better than original hydraulic units. Popular brands include KYB, Monroe, and Bilstein. Ensure you get the correct mounting type – some Studebakers have stud-type mounts, others have eyelet ends.

Bushings and Mounts

Rubber bushings deteriorate with age. Replace them with polyurethane for longer life and sharper handling, or stay with rubber for a more original feel. Control arm bushings, sway bar bushings, and spring bushings are all commonly available.

Control Arms and Ball Joints

Front control arms may need rebuilding or replacement. Ball joints are critical safety parts. Many Studebaker-specific ball joints are still produced or can be sourced as NOS (New Old Stock). Check for play when inspecting.

Sway Bars (Stabilizer Bars)

Sway bars reduce body roll in corners. If your car has one, replace the bushings and links. Adding a larger sway bar can improve handling, but ensure compatibility.

Sourcing Studebaker Suspension Parts

Original Equipment (OE) and NOS

New Old Stock parts can be found at swap meets, online forums, and specialty dealers. They are original quality but may have been sitting on shelves for decades. Inspect rubber parts for cracks before buying.

Aftermarket Reproductions

Many companies reproduce Studebaker suspension components. Brands like Kanter, Classic Industries, and Studebaker International offer parts. Quality varies, so ask fellow restorers or check forums for recent experiences. Some aftermarket parts use modern materials (like polyurethane) that improve durability.

Rebuilding vs. Buying New

Rebuilding original components (like control arms with new bushings and ball joints) can save money and maintain originality. However, if the metal is rusted or damaged, new parts are better.

What to Avoid

• Cheap, unbranded parts – They may not fit or last.
• Parts from unknown sellers without return policies.
• Modifications that compromise safety, like lowering springs without supporting changes.

Installation Tips and Considerations

• Safety first – Use jack stands, never a floor jack alone. Suspension work involves heavy springs that can cause injury if not compressed properly.
• Spring compressors – Coil spring compressors are essential for front spring removal. Leaf springs require careful unbolting and may need a helper.
• Alignment – After replacing suspension parts, a professional alignment is necessary to adjust camber, caster, and toe. Many older Studebakers have adjustable shims for alignment.
• Hardware – Use new bolts, nuts, and washers. Torque to factory specs. Studebaker parts often require SAE fasteners.
• Lubrication – Grease fittings on ball joints and tie rods should be greased after installation.

Recommended Brands and Products

While specific product endorsements are not made here, several brands are consistently mentioned by Studebaker enthusiasts:

• Kanter Auto Products – Offers complete suspension kits for many models.
• Eaton Detroit Spring – Specializes in leaf springs and coils for classic cars.
• Studebaker International – Carries a wide range of NOS and reproduction parts.
• Prothane or Energy Suspension – For polyurethane bushings.

Check online forums (such as the Studebaker Drivers Club Forum) for current recommendations and experiences.

Final Recommendation

Start by diagnosing your suspension issues: inspect bushings, check for play, measure ride height, and look for leaks. Determine whether you need just a few components or a full overhaul. For most owners, a combination of quality aftermarket springs, modern shocks, and polyurethane bushings provides the best balance of ride, handling, and longevity. If originality is paramount, seek NOS parts or restore your original pieces. Always prioritize safety – brakes and steering are equally important. With the right parts and careful installation, your Studebaker will ride and handle like new.
