Cadillac STS Replacement Skid Plate Information


You usually find a Skid Plate on 4x4 vehicles, but you may find it on many other vehicles including the Cadillac STS. A Skid Plate is usually designed from metal or plastic and is affixed to the vehicle with metal bolts. The purpose of this component is to protect specific components of off-road vehicles such as the transmission or the fuel tank since these items are quite difficult to replace. This plastic or metal cover is affixed to the underside of a car in order to protect those hard-to-replace components. In ordinary vehicles the Skid Plate is a heavy-gauge metal plate attached to the underside of the vehicle to prevent damage to the underside of the car. Driving a Cadillac was a smart choice, now maintaining it in top condition is an even better idea!


They are available for the following Cadillac STS years: 2011, 2010, 2009, 2008, 2007, 2006, 2005, 11, 10, 09, 08, 07, 06, 05. This part is also sometimes called Cadillac STS Engine Cover. We stock skid plate parts for most Cadillac models including CTS, DeVille, Escalade and Escalade EXT.

We stock these Skid Plate brands for the Cadillac STS: Action Crash.

    The cover was shipped right away, and fit like a glove. I had read online somewhere that Action Crash parts were junkyard parts, but this piece was brand new....my expectations were exceeded.

    Very Satisfied
    Reviewer: Great price

    Shopped around and found Parts Geek to have the best price. Received it in expected time frame. Product fit like the original. Only deviation from OEM was the omission of a foam spacer which I had to use from the original part.
