Downforce Solutions: Splitters, Wickerbills, Diffusers and More for Your Mopar
A finished Mopar build looks intentional from every angle. Downforce Solutions brings more than rear wickerbills to the table: Merrick Motorsports carries front splitters, side splitters, rear diffusers and an engine/transmission cover, too. Here are nine products to help plan your next project. These are application-specific choices, not one universal kit.
Challenger Wickerbill: Start With Your Factory Spoiler
The 2015–2023 Challenger SXT, GT, RT, SRT and Demon wickerbill listing describes laser-cut, powder-coated aluminum with dip and no-dip choices. Its fitment information specifies the factory spoiler configuration and particular trims, including non-Widebody applications. Match the spoiler itself rather than ordering from the model year alone.

Charger Widebody Wickerbill: A Different Application

The 2020–2023 Charger Hellcat Widebody wickerbill listing identifies Daytona, Hellcat and Redeye Widebody applications. It includes stainless bolts, billet washers and nutserts. Do not substitute this part for a different factory spoiler just because both cars wear a Widebody badge.

Challenger Rear Diffuser: Finish the Lower Rear Profile

The 2015–2023 Challenger rear diffuser is described as an all-aluminum welded assembly with powder-coated billet mounting brackets. Its fitment list separates the listed standard-body trims from 2020–2023 Widebody applications. Review that list and your existing exhaust arrangement before planning the installation.

Charger Widebody Front Splitter: Bring the Front Into the Plan

This front splitter is listed for 2020–2023 Charger Widebody applications. The description specifies aluminum construction, a powder-coated finish and chassis mounting. Confirm mounting requirements and the selected configuration before ordering. The photo shows an example installation, not a promise that every pictured accessory comes with every selection.

Challenger Widebody Front Splitter: Choose the Correct Body Style

The Challenger Widebody splitter uses T6061 aluminum with chassis-mount brackets and integrity plates. The listing specifies the 2018 Demon Widebody and listed 2019–2023 Scat Pack, Hellcat and Redeye Widebody applications. A front strut-rod kit is optional. Read the mounting instructions carefully: the listing describes both factory attachment locations and additional drilling.

Challenger Side Splitters: Connect the Exterior Details

The 2011–2023 Challenger side-splitter listing describes aluminum panels attached to a chassis-mounted rail. Powder-coat and custom cutout choices give shoppers another way to coordinate their exterior. Check the application and mounting guidance for your particular car before choosing the finish.

Charger Side Splitters: Check the Rocker Panels

The Charger side splitters have a specific requirement: the listing calls for the factory SRT Appearance Package and identifies the rocker panels they are designed around. Its fitment list separates trims and years within 2015–2023. A Charger badge is not enough to establish fitment, so verify your rocker-panel configuration.
Engine and Transmission Cover: Look Beneath the Car

The 2015–2023 Challenger and Charger cover replaces the plastic panel below the engine. The listing describes an aluminum construction, a powder-coated finish, four original mounting bolts and two additional bolts at a custom transmission bracket. Automatic and manual choices are available, so match the transmission when selecting the part.

Chrysler 300S Wickerbill: A Sedan-Specific Finishing Touch

Chrysler owners have a separate 2015–2023 300S wickerbill listing. It offers powder-coat colors, billet washers, stainless hardware and cutout choices. Use this product's application details rather than trying to adapt a Charger or Challenger wickerbill by appearance.

Build the Shopping List Before the Installation Weekend
Start with the year, trim, body style, spoiler and mounting surfaces on your actual vehicle. These products are made to order; check current lead times and configuration details on the linked listings before scheduling the work. Several listings specify a 1/4-20 rivnut tool. Review the individual installation instructions and confirm which optional components are included in your selection. This guide does not promise measured aerodynamic or handling gains. Explore Downforce Solutions at Merrick Motorsports and choose the parts that fit your build from front to rear.
