Corvette C4 Rear Diffuser 1984-1996

$198

A rear diffuser mounts at the base of the rear bumper, adding layered detail to the tail and helping air exit smoothly from underneath the car. On the 1984-1996 Corvette C4, the factory rear bumper leaves a plain, unadorned area at its base, and fitting a diffuser fills that gap, giving the tail a fuller and more complete appearance. This diffuser is molded from premium PP and offered in gloss black, matte black, or a carbon-fiber-textured finish.

Product Features

Fitment covers the mainstream 1984-1996 Corvette C4 lineup.

The PP material used matches the flex characteristics of the OEM factory bumper, giving it strong resistance to impact along with the flexibility to bend rather than crack under minor contact - a meaningful advantage given how low the C4 sits and how often its lower bumper area takes minor hits.

Developed from 3D scan data of the factory rear bumper, the diffuser's curvature closely matches the car's existing lines once installed. Beyond filling in the visual gap at the base of the bumper, the flexible PP material resists cracking under minor impact, stays supple in cold weather, and resists long-term outdoor aging and deformation.

Installation uses the car's factory-provided mounting holes with bolted hardware or 3M adhesive, and this diffuser suits everyday street styling upgrades as well as classic car restoration work.
