Made from High strength polycarbonate light weight plastic w korad kap and is UV stable. Unlike fiberglass, this material has some give like the stock air dams in case you hit a parking curb. This air dam is approximately 1" taller than the stock 2 piece air dam used on the 86 and 87 Buick Grand National's. It looks similar to the material used on the stock air dams. Air Dam mounts to holes on the bottom of the factory bumper.
This part works great on Buick Grand Nationals that have been upgraded to a front mount intercooler and longer need the factory split air dam. It also looks great on Regals that desperately need a chin spoiler that didn't come with one from the factory.
