Direct-fit lower control arm bumper designed for 1955-1957 Chevrolet passenger cars (Tri-Five models). This bumper cushions lower control arm travel to prevent metal-to-metal contact, protect suspension components, and restore proper ride height and handling. Molded from high-grade polyurethane for long service life and resistance to oil, grease, and weathering. A durable, reliable replacement that reduces noise and vibration while being straightforward to install — ideal for restorations and routine suspension maintenance.
Features:
- Fits 1955-1957 Chevrolet passenger cars (Tri-Five models).
- High-grade polyurethane construction for long-lasting durability and chemical resistance.

Installation / Application:
- Difficulty: 2/5
- Estimated time: 30-60 minutes per axle
Instructions:
- Park on level ground, engage parking brake and chock rear wheels; slightly loosen front wheel lug nuts.
- Raise the front of the vehicle and support securely on jack stands. Remove the front wheels.
- Support the lower control arm with a jack or jack stand so it is held slightly lower than the frame (relieves pressure on the bumper).
- If present, remove any retaining hardware or brackets holding the old bumper. Pry or cut out the old deteriorated bumper as needed, taking care not to damage the mounting bore.
- Clean the bumper mounting bore thoroughly with penetrating lubricant and a rag to remove dirt, rust, and debris.
- Align the new polyurethane bumper with the mounting bore and press it into place. Use a rubber mallet or dead-blow hammer to seat it fully; ensure correct orientation and full engagement.
- Slowly raise the lower control arm back to ride height and verify the bumper is properly seated and captures the control arm travel.
- Reinstall the wheels, lower the vehicle, and torque lug nuts to manufacturer specification. Test drive at low speed to confirm proper operation and absence of unusual noise.
