First off, lets clear the air, these are by no means what most would consider a traditional fender flare, or a cut out flare, not even close. These fender flares from the masterminds at AEV are literally the same quality you would expect from OE, and probably better than that honestly, and took over three years of arduous research and development to come out with a final product. This unique kit includes not only the flares but all the details to finish the job professionally, including new wheel liners, structural steel reinforcements, additional marker lights, and will allow the fitment of up to 41 of suspension lift.

Please note that this kit is for the rear pair only.

This kit is available both for Rams featuring a standard bedside, as well as those with integrated RamBox's (access door to compartment built into bedsides).

The Ram HD trucks benefit immensely from a larger tire footprint and this kit is just the ticket, providing all the benefits of a large tire off-road, while maintaining a low center of gravity for safety and optimized handling on the road. The AEV Highmark Fender Flare Kit is designed to work together perfectly with AEV's 17x10 Katla Wheel, Premium Front Bumper and 3" DualSport SC Suspension System.

The Highmark Flare construction is extremely unique, in fact the only vehicle that uses a similar construction is the Mercedes Unimog, and even at that, the AEV kit uses a much stronger version. While most aftermarket flares are simply a thin single sheet of vacuum formed plastic, AEV chose to use rotomolded polyethylene (similar to a whitewater kayak) for the ultimate in strength. This kit simply can't be compared to anything else currently found in the aftermarket. These flares are a fully enclosed, ¼" thick highly durable part that provides approximately 4.5" of additional coverage per side.

Designed and manufactured using OE-level processes, the Highmark Fender Flare Kit gives your truck aggressive styling and an imposing stance with a factory fit and finish that are second to none. Tested and verified to function correctly between -40F and 140F, these flares won't let you down. Additionally, the AEV Highmark Fender Flare Kit complies with US DOT passenger vehicle width regulations and includes auxiliary front and rear LED marker lights. Optional AEV Rear Splash Guards are also available to comply with state and local regulations.

AEV Highmark Fender Flares are proudly made in the USA and are available as a complete kit or a standalone front set intended for customers who are using a utility body, cab chassis, custom bed or camper configurations.

IMPORTANT NOTE: The AEV Highmark Fender Flare Kit was designed and engineered to be used in conjunction with AEV's Premium Front Bumper, 3" DualSport Suspension System and 17x10 Katla Wheels. For that reason, AEV cannot guarantee tire clearance and compatibility when used with other manufacturers' front bumpers, wheels and/or suspension systems and steering components. Professional installation is highly recommended. Some steering stop adjustment may be required depending on tire and wheel choice.

1. Can the AEV Dual Sport Suspension, the AEV High Mark Fender Flares and the AEV front Bumper be installed on a 2014 - 2019 RAM 2500 with a HD 6.4L Gasoline drive train? I would prefer to own a gasoline truck verses a diesel truck. 3. Is the Howitzer build based on a RAM 2500 HD Regular cab with an eight foot pickup bed, or was the vehicle modified for a short six foot four inch pickup bed? Thank-you?

Yes, those items will work on the gas engine as well. As far as Howitzer, that started life as a regular cab long bed. We cut it in half and installed a rear frame off of a crew cab short bed 2500. We could then install the rear coil suspension and have a short bed!-TL


Will the high mark flares work on a regular bed dually??

No it will not work on a Dually application. DppSands
