The 73 87 rear bumper defines the specific rear-end styling and protection for vehicles produced in the 1973 to 1987 model years. This component covers mounting brackets, impact structures, and trim pieces that vary by make and body style.
Understanding this bumper assembly helps owners maintain authenticity, improve durability, and support proper towing or loading capability. The following sections break down design, compatibility, upgrades, and real-world questions from drivers.
| Model Year Range | Common Applications | Bumper Type | Key Features |
|---|---|---|---|
| 1973–1978 | Full-size trucks, vans | Heavy gauge steel | Higher tow ratings, boxy profile |
| 1979–1982 | Mid-size cars, SUVs | Hybrid steel/composite | Blended styling, moderate load capacity |
| 1983–1987 | Light trucks, sedans | Corrosion-resistant steel, urethane guards | Improved fuel alignment, integrated tow hooks |
Design and Construction of 73 87 Rear Bumper
During the 1973 to 1987 period, manufacturers used steel, hybrid steel-composite, and later urethane overlays to balance strength and appearance. Early designs emphasized crash durability for heavy trucks, while later versions focused on aerodynamics and integration with body cladding.
Mounting points often match frame rails and suspension components, so installers must verify spacing and alignment. Protective liners, anti-rust coatings, and reinforced tow loops are common features that define long-term reliability.
Compatibility and Fitment for 73 87 Rear Bumper
Fitment depends on vehicle make, model, cab configuration, and Gross Vehicle Weight Rating (GVWR) within the 73 87 window. A truck sold in different markets may have distinct bumper brackets, even if the sheetmetal appears identical.
Before purchase, confirm year-specific diagrams, check for optional towing packages, and review whether the bumper pairs with auxiliary lighting or skid plates. Aftermarket suppliers often list applications by VIN or trim code for precision.
Upgrades and Material Options
Owners can choose OEM replacements, aftermarket heavy-duty versions, or modern composite bumpers that reduce weight and resist corrosion. Some upgrades include integrated step bars, brush guards, and receiver hitches that expand functionality without multiple installations.
Material choices affect cost, weight, and repairability. Steel offers toughness but may rust, while high-strength composites resist damage in corrosive climates but can be pricier and require specialized installation.
Maintenance and Inspection Guidelines
Regular checks of welds, mounting bolts, and impact shields help prevent unexpected detachment on the road. Look for rust penetration around mounting holes, deformed corners, and cracked trim pieces during visual inspections.
Cleaning with pH-balanced products, applying anti-corrosion treatments, and re-torquing hardware after seasonal temperature changes extend service life. For vehicles used off-road or for towing, more frequent inspections are recommended.
Performance and Safety Considerations
The 73 87 rear bumper contributes to structural energy absorption during low-speed impacts and affects rearward visibility when carrying cargo. Selecting a model that maintains proper trailer ball height and keeps lighting unobstructed supports safer operation.
Verify that any replacement meets original equipment towing and speed ratings, especially if the vehicle is used for hauling or commercial work. Upgraded bumpers with built-in sensors can improve parking accuracy and reduce collision risk in tight areas.
Recommendations for Selecting and Installing 73 87 Rear Bumper
- Confirm exact application using year, model, and VIN before ordering.
- Choose material and construction suited to your climate and usage (steel for rugged terrain, composite for corrosion-prone areas).
- Verify towing and safety ratings match or exceed original equipment specifications.
- Inspect mounting surfaces and repair any frame rust before installation.
- Use factory-grade fasteners and follow torque specs to maintain structural integrity.
- Test lights, sensors, and backup aids after installation to ensure proper function.
- Schedule periodic inspections if the vehicle is used for frequent towing or off-road driving.
FAQ
Reader questions
Will a 1985 model fit a 1976 frame without modifications?
Not always, because emission regulations, safety mounts, and wiring looms changed between those years. Verify bracket locations, sensor placement, and connection types before assuming compatibility.
How do I confirm towing capacity when installing a new rear bumper?
Check the vehicle’s original GVWR and trailer tongue weight limits, then compare them to the upgraded bumper’s ratings. Match or exceed the manufacturer’s tow specifications to stay within safety and insurance guidelines.
What signs indicate that the rear bumper needs replacement rather than repair?
Severe cracks, frame distortion, compromised mounting points, or persistent misalignment after adjustment usually signal that replacement is safer and more cost-effective than welding or patching.
Are aftermarket bumpers covered by warranty if used for commercial towing?
Many aftermarket brands offer limited warranties, but coverage can be voided if the bumper is used beyond its rated GVWR or tow capacity. Review the terms and required documentation to ensure claims remain valid.
