2020+ Duramax HD Finishing Caps

Fits

Give your 2020+ GM Heavy Duty truck a cleaner look and much-needed tire clearance. These Trigger Finishing Caps are designed as a direct replacement for your bulky factory splash guards. By significantly reducing the overall height of the trim, these caps allow you to mount your mudflaps higher up and closer to the fender—the perfect solution for trucks running oversized tires or aggressive offsets that normally rub on the OEM plastic.

Built to handle the abuse of Canadian roads, these caps are finished in a durable black powder coat to blend seamlessly with your wheel wells. Whether you are running a single-rear-wheel (SRW) setup or a dually (DRW), these finishing caps provide the ultimate "big tire" fix without having to hack up your factory trim.
