Urethane bumpers were originally installed on Corvettes at the factory. They will absorb low speed impacts without bumper damage but they have a marginal fit and are subject to warping over time. Color matches on urethane bumpers may be more difficult because a flex agent must be added to the paint, resulting in color shifts. Corvette Central now offers TruFlex bumpers, which are constructed of fiberglass and a revolutionary new resin, which makes them 70% more flexible than standard fiberglass bumpers. After fitting, they can be painted without adding a flex agent to so exact paint matches are easier to achieve. Early '76 rear bumper covers had a depression for the 'Corvette' name plate.
All fiberglass replacement parts are considered collision parts and should be fit to the car before final finishing. It is normal for these parts to have chips, scratches, and even minor cracks when received. This is considered to be normal and is not a reason for parts replacement.
There is a $10.00 Packaging Charge.
