ACS-C7 Stingray / Grand Sport / Z06 / ZR1 Enhanced Front Mudflaps Splash Guards

ACS-C7 Stingray / Grand Sport / Z06 / ZR1 Enhanced Front Mudflaps Splash Guards

ACS Enhanced Front Mud Flaps for C7 Corvette ZR1, Z06, Grand Sport, and Stingray | Part Number 45-4-063

The Problem

We found the GM accesory splash guards to be too small and ineffective at protecting the Corvette's paint from rock chip damage. It is even worse when your Corvette is fitted with Side Skirts as the front leading edge of the rocker will get eroded over time from road surface debris. See image below.

Notice how the mudguard is does not reach the bottom of the side skirt. Nor will it sufficiently protect your Rear Brake Scoop on a Grand Sport, Z06, or ZR1.

The culprit behind the issue are the performance tires mounted on the Corvette's wheels. They are incredibly sticky at temperature and will collect any and all road surface debris including gravel and stone chips. As you drive, the debris will release from the tires and b-line it towards your Corvette's paint causing serious paint chip damages. We've designed our own series of rock guards, splash guards, & mud flaps to combat this issue and keep your Corvette protected.

Our Solution

The ACS Enhanced Front Mud Flaps are 15mm longer and 30% wider than the GM splash guards; thus, offering enhanced protection to your side rockers and the side of the car. In particular, for the ZR1, Z06, & Grand Sport, we designed our mud flaps to curve which offers more protection to the rear brake scoop. In combination with a set of side rockers, paint damage and chipping can be reduced.


Will fit on all C7 Corvettes (2014-2019) ZR1, Z06, Grand Sport, Stingray, Stingray Z51.

The ACS Enhanced Front Mud Flaps are injected in an ABS black plastic texture, which has been meticulously designed to match the rear GM mudguards, which means that, if customers already have them, then they need only to upgrade the fronts!

Rapid Installation

The ACS Enhanced Guards install using the three (3) screws that currently hold your wheel liner in place. Simply remove the 3 screws, place the guards over the liner, bolt in place. No drilling or modifications needed. Install can be completed in under 30 minutes. Check out our install video: 

Elegant Design

Our enhanced mud flaps are beautifully styled to match the sleek contoured design of the C7. We take OEM data from the Corvette, and engineer our guards from the ground up to ensure that the guards you receive are not just a universal guard, but a mudflap that is tailor made for the C7 Corvette.

The injected black ABS components not only match GM rear guards, but also look the business! However, if you wish for a different surface finish such as Carbon Flash, then those are available. 

Take a look at the GIF below for a look at the distinction between the ACS Enhanced Mud Flap in Carbon Flash, Textured and the GM counterpart.

The Conclusion

Whether you are a Z06 or Stingray owner you will be delighted with the wider enhanced protection of the rear brake cooling scoop, door and undercarriage of your car.

Looking for More Protection?

We released a bigger and better version of the front splash guards called our XL (for extra large) mud flaps for the Chevrolet C7 Corvette. Fits all models, Stingray, Grand Sport, Z06, or ZR1. You can find them below:

They say bigger is better, and that is definitely the case with our XL mud flaps. The XL rock guards are nearly double the protection of the GM mudguards and the ACS Composite Enhanced Front Splash Guards.

Have you heard the noise of rocks and road surface debris chipping away at your paint? You can thank those large sticky performance tires for that. Reduce the rocks thrown up towards the car, and save on time and money on paint chip repairs. The XL rock guards will prevent rocks from getting to those precious areas of your C7 Corvette.

Manufactured in a black ABS-PC plastic, the rock guards will withstand the impact of rocks and other road debris while protecting your Corvette.

Sold as a set; Each set contains a passenger and driver side. 

New Feature

A newly developed unique bladed shield on the edge of the rock guard stops any debris from directly entering the wheel well. A small detail that could save a big headache.

How do they install?

The XL guards come press clips that snap into place. No extra drilling, cutting, or other modifications necessary. Simply snap in, and drive comfortably knowing that your Stingray, Grand Sport, Z06, or ZR1 is protected.
