Complete Guide to 1996 Chevy Impala SS Suspension Parts

The 1996 Chevrolet Impala SS is a beloved muscle sedan known for its LT1 V8 engine and aggressive stance. But to truly enjoy its performance, the suspension must be in top shape. Whether you're restoring to factory specs or upgrading for better handling, this guide covers every suspension part you need for the 1996 Impala SS.

Front Suspension Components

The front suspension on the B-body Impala SS uses a modified version of the GM B-car setup. Key parts include control arms, ball joints, strut rods, and sway bar.

Upper and Lower Control Arms

Stock upper control arms are stamped steel with pressed-in ball joints. Many owners upgrade to tubular arms for better caster adjustment and weight savings. Lower control arms are robust but can benefit from polyurethane bushings to reduce deflection.

Ball Joints

Factory ball joints are non-greasable. When replacing, consider greasable aftermarket units for longer life. Moog K5093 (upper) and K6364 (lower) are common direct-fit replacements.

Strut Rods and Bushings

The strut rods connect the lower control arm to the frame. Bushings wear over time causing vagueness. Polyurethane strut rod bushings from Energy Suspension or Prothane stiffen the front end and improve steering response.

Coil Springs and Shocks

Factory springs are soft for comfort; performance springs from Eibach or Hotchkis drop the car 1-1.5 inches and reduce body roll. Pair with quality shocks like Bilstein or KYB Gas-a-Just for better damping.

Sway Bar

The 1996 Impala SS came with a 36mm front sway bar – one of the largest from the factory. Still, upgrading to a thicker bar (38-40mm) from Addco or Hellwig further reduces roll. Don't forget polyurethane bushings and end links.

Rear Suspension Components

The rear uses a solid axle with leaf springs. Key parts: leaf springs, shocks, control arms (traction bars), and sway bar.

Leaf Springs

Factory springs sag over time. New stock replacements are available from AC Delco, but many prefer lowering leaf packs from Eibach or Hotchkis that drop the rear 1-1.5 inches while improving stability. Mono-leaf conversions are also popular for weight reduction.

Shocks

Rear shocks are vertical mount. Bilstein 24-186774 and KYB KG5436 are gas-charged options that control wheel hop. For adjustability, QA1 adjustable shocks allow tuning for street or strip.

Traction Bars / Control Arms

Wheel hop is a common issue under hard acceleration. Traction bars (e.g., Lakewood or BMR Fabrication) mount to the axle and control arm to limit axle rotation. Boxed rear lower control arms with polyurethane bushings also reduce deflection.

Rear Sway Bar

The 1996 Impala SS has a 28mm rear sway bar. An aftermarket 28-30mm bar from Addco or Hellwig further balances the chassis. Ensure end links and bushings are replaced with the bar.

Steering and Alignment Parts

Steering feel is heavily influenced by tie rods, idler arm, pitman arm, and steering box.

Outer and Inner Tie Rod Ends

Factory tie rods wear quickly. Moog ES3557RI (outer) and ES3556LI (inner) are direct replacements with improved grease boots.

Idler Arm and Pitman Arm

The idler arm supports the passenger side center link. A worn idler arm causes wandering. Moog K6457 idler arm and K6394 pitman arm are heavy-duty choices.

Steering Box

Stock units have a high ratio (12.7:1). Rebuilds with quicker ratio (14:1) are available from Turn One or Redhead Steering. A properly adjusted box transforms steering response.

Suspension Upgrade Kits vs. Individual Parts

You can buy a complete suspension kit or piece it together. Kits from Hotchkis or Detroit Speed include matched springs, shocks, sway bars, and bushings. These ensure balanced handling. For budget builds, replace worn parts individually with OEM-equivalent or slightly upgraded parts.

Installation Tips

• Always use new nuts and bolts when removing suspension components. Gas shocks are recommended – they resist fade better than hydraulics.
• After installing lowering springs, get an alignment with adjustable camber bolts if needed.
• Polyurethane bushings need lubrication; use the supplied grease or silicone-based lube.
• Torque all fasteners with the car’s weight on the ground (curb height) unless specified otherwise.

Cost Breakdown

• Basic OEM replacement parts (ball joints, tie rods, shocks): $400-$700
• Parts-only upgrade (springs, sway bars, bushings): $800-$1500
• Full handling kit (springs, shocks, sways, control arms): $1500-$3000
• Labor if not DIY: add $500-$1000 (rusty bolts can increase time).

Final Recommendation

For daily driving, replace all worn bushings and ball joints with OEM-quality parts, and add Bilstein shocks. That alone transforms the ride. For autocross or spirited street driving, invest in a matched set of lowering springs (Eibach Pro Kit), Bilstein shocks, and polyurethane bushings. For hard launches, traction bars are essential. Avoid cheap, unbranded parts – stick with Moog, AC Delco, Energy Suspension, Bilstein, Eibach, Hotchkis, or BMR.

By focusing on the suspension parts outlined above, you can return your 1996 Impala SS to its former glory or turn it into a corner-carving beast.
