1964-1974 GM car lower control arm (A-arm) bumper designed to protect suspension components by cushioning and limiting lower control arm travel. This replacement bumper prevents metal-to-metal contact, reduces noise and vibration, and helps preserve the control arm and frame mounting points. Constructed for long life and repeated service, it restores proper bump-stop function for classic GM cars, improving ride quality and prolonging the life of steering and suspension parts. Easy to install as a direct replacement during routine suspension work or restoration projects.
Features:
- Fits 1964–1974 GM cars — check application for exact models and mounting style
- Made from high-durometer polyurethane for long-lasting durability and resistance to oil, grease, ozone and weathering
- Cushions the lower control arm (A-arm) to prevent metal-on-metal contact and component damage
- Reduces suspension noise and vibration; restores original bump-stop travel and ride characteristics
- Direct replacement for worn or missing bumpers — simple installation during suspension maintenance or restoration
Installation / Application:
- Difficulty: 2/5
- Estimated time: 30-60 minutes
Instructions:
- Park vehicle on a level surface, engage parking brake and place wheel chocks behind rear wheels.
- Loosen front wheel lug nuts, raise the front of the vehicle with a floor jack and support securely on jack stands. Remove the wheel.
- Locate the lower control arm bumper on the control arm or frame bracket. Support the control arm with a jack or block to relieve tension on the bumper.
- Apply penetrating oil to any rusted fasteners if applicable. Remove the old bumper by prying or tapping out with a punch; in some designs the bumper pulls off or presses out.
- Clean the mounting area with a wire brush and rags; remove rust, dirt and old rubber residue to ensure a proper seating surface.
- Lubricate the new bumper lightly with soapy water or a small amount of silicone grease to aid installation. Press or tap the new bumper into place using a rubber mallet or by pressing it into the bracket until fully seated.
- Lower the control arm slowly to take up the bumper and confirm proper seating and alignment with the frame or bracket.
- Reinstall the wheel, hand-tighten lug nuts, lower the vehicle, and torque lug nuts to manufacturer specifications.
- Test drive at low speed to verify noise reduction and proper suspension travel. Recheck the bumper seating after a short break-in drive.
