Warnings

Tools required

Parts

• Rear bumper reinforcement bar × 1 — Use OEM specification
• Bumper cover mounting hardware × 1 — Replace if damaged

Preparation

1. Park vehicle on level surface and apply parking brake
2. Place wheel chocks at front wheels
3. Allow exhaust system to cool completely if vehicle was recently driven
4. Inspect work area for adequate lighting and clearance around rear of vehicle

Procedure

1. 1

   Access rear bumper cover fasteners
   Access the upper bumper cover mounting points from the rear deck/body area. Note that the 1992 Viper is a front-engine vehicle with a fiberglass body and minimal rear storage, so there is no conventional trunk; locate the fasteners securing the top edge of the bumper cover to the body structure. Locate the fasteners securing the top edge of the bumper cover to the body structure. The exact access location for these fasteners on the 1992 Viper should be verified against the factory service manual before proceeding.
2. 2

   Remove rear bumper cover upper fasteners
   Remove the upper bumper cover mounting bolts or screws from inside the rear compartment. Verify the exact number and type of upper edge fasteners against factory documentation before removal. Keep all hardware organized for reinstallation.
3. 3

   Remove lower and side bumper cover fasteners
   Working from underneath and along the sides of the bumper cover, locate and remove the lower mounting fasteners. These secure the bumper cover to the lower body structure and wheel well areas. Verify the exact number and locations of the lower and side mounting fasteners against factory documentation before removal.
4. 4

   Disconnect any electrical connections
   Check whether any electrical connections (e.g., license plate lamp) run near the bumper cover and disconnect them if present. On the 1992 Viper, rear lighting is generally body-mounted rather than integrated into the bumper cover; verify no connectors are under tension before removing the cover completely.
5. 5

   Remove rear bumper cover
   With an assistant supporting the opposite side, carefully pull the bumper cover away from the body. The cover may have alignment tabs or clips that require gentle persuasion. Support the fiberglass cover to prevent flexing or cracking. Place the cover on a padded surface with the exterior face up to prevent scratches.
6. 6

   Locate bumper reinforcement bar mounting points
   With the bumper cover removed, the metal reinforcement bar is now visible. It mounts to the rear tubular space-frame structure via mounting brackets; verify the exact attachment points against factory documentation. Identify all mounting bolts securing the reinforcement bar to the chassis.
   ⚠The reinforcement bar may be heavy. Support it before removing the final fasteners to prevent it from falling.
7. 7

   Remove reinforcement bar mounting bolts
   Remove the mounting bolts securing each end of the reinforcement bar to the chassis brackets. Verify the exact bolt count per side for the reinforcement bar mounting against factory documentation before removal. Support the reinforcement bar as you remove the final bolts.
8. 8

   Remove reinforcement bar
   Carefully remove the reinforcement bar from the vehicle. Inspect the mounting brackets and chassis attachment points for damage, corrosion, or wear. Clean the mounting surfaces if installing a new reinforcement bar.
9. 9

   Prepare new reinforcement bar
   Inspect the new reinforcement bar for shipping damage and verify it matches the original configuration. Compare mounting hole locations and overall dimensions. Transfer any mounting brackets or hardware from the old bar if they are reusable and in good condition.
10. 10

    Install new reinforcement bar
    Position the new reinforcement bar onto the chassis mounting points. Align the mounting holes with the brackets. Thread in all mounting bolts finger-tight before final torquing to allow for alignment adjustment.
11. 11

    Torque reinforcement bar mounting bolts
    Torque all reinforcement bar mounting bolts to specification in a cross-pattern (alternating sides) to ensure even seating. Verify the bar is centered and aligned properly before final torquing.
12. 12

    Reinstall rear bumper cover
    With an assistant, position the rear bumper cover back onto the vehicle. Align the mounting tabs and holes with the body structure. Ensure any alignment pins or guides engage properly before installing fasteners.
13. 13

    Install bumper cover fasteners
    Install and torque all bumper cover mounting bolts in the reverse order of removal: upper fasteners first, then lower and side fasteners. Torque to specification to avoid over-tightening and cracking the fiberglass cover. Reconnect any electrical connections for rear lighting.

Reassembly

1. Ensure all bumper cover fasteners are torqued to specification to prevent rattles without over-stressing the fiberglass
2. Verify even gaps between bumper cover and body panels on both sides
3. Test any rear lighting functions to confirm electrical connections are secure

Verification

• Visually inspect bumper cover alignment and fitment from multiple angles
• Check for even gaps between bumper cover and adjacent body panels
• Gently push on the bumper cover at multiple points to verify secure mounting with no excessive movement
• Verify all fasteners are installed and properly torqued
• Confirm rear lighting functions properly if applicable
