The Dodge Challenger Redeye has long been a benchmark for American muscle, packing a supercharged 6.2L HEMI V8 that delivers 797 horsepower straight from the factory. As we move through 2024, the aftermarket support for this platform has never been stronger, with enthusiasts pushing these cars well beyond stock performance. NashvillePerformance.com has curated a selection of performance parts that represent the pinnacle of engineering for the Redeye—components that deliver measurable gains in power, handling, and visual presence without compromising reliability. Whether you are chasing quarter-mile times, carving canyon roads, or simply want your Redeye to sound as aggressive as it looks, the following upgrades are worth serious consideration.

Engine Performance Upgrades

The heart of the Challenger Redeye is its 2.7L IHI supercharger and the robust 6.2L HEMI V8. While the factory tuning is impressive, there is significant untapped potential. Upgrading air intake, exhaust, and supercharger components can unlock 100+ horsepower while improving drivability.

Cold Air Intake Systems

A cold air intake is one of the simplest and most cost-effective upgrades for the Redeye. The factory air box, while functional, creates restrictions that limit air volume and allow heat soak. High-quality aftermarket systems like the AFE Power Momentum GT or K&N Blackhawk use larger filters, smooth mandrel-bent tubes, and heat shields to drop intake air temperatures by 20–30°F. This denser air charge can yield gains of 15–20 horsepower on a stock Redeye and even more when combined with a tune. NashvillePerformance.com recommends systems that include a sealed intake box to prevent sucking in hot engine bay air during traffic or stoplight launches.

Performance Exhaust Systems

Replacing the factory exhaust is critical for both sound and power. The Redeye’s stock exhaust uses restrictive mufflers and resonators that choke flow at higher RPM. A cat-back or axle-back system from Borla, Corsa, or MagnaFlow can free up 10–15 horsepower while delivering a deeper, more aggressive note. For those seeking maximum gains, a full header-back system with long-tube headers (e.g., American Racing Headers or Kooks) paired with a high-flow mid-pipe can add 30–40 horsepower at the wheels. However, buyers should be aware that headers can require a custom tune to avoid check engine lights and may not be legal in all states due to emissions regulations.

Supercharger Upgrades and Pulley Kits

For owners hungry for four-digit horsepower, the supercharger is the primary target. The factory 2.7L IHI unit can be spun faster with a smaller pulley. A 2.85-inch or 2.75-inch pulley kit from manufacturers like Ripa, Kong, or Dusterhoff can increase boost from 11.6 psi to 16–18 psi. Combined with a larger throttle body (e.g., Mighty Mouse 105mm) and upgraded heat exchanger (e.g., AFE Power intercooler), these mods can push the Redeye well past 850 wheel horsepower. It is essential to complement pulley swaps with a reliable E85 or race fuel tune to prevent detonation. Many shops also recommend upgrading the fuel system with higher-flow injectors and a boost-a-pump to maintain safe fuel pressure at higher boost levels.

Fuel System and Tuning Considerations

Any serious power increase demands attention to fuel delivery. The Redeye’s direct injection system can run out of capacity beyond 750 wheel horsepower. Upgrading to ID1050x or Injector Dynamics 1300cc injectors along with a second fuel pump (e.g., Fore Innovations triple pump setup) ensures consistent flow. Tuning is equally critical—a custom calibration from a reputable tuner like HP Tuners or DiabloSport (with in-house dyno support) optimizes timing, fuel curves, and transmission shift pressures. Many NashvillePerformance.com customers pair parts with a remote or local dyno tune to ensure reliability while extracting maximum power. Data logs showing air-fuel ratios and knock sensor activity are invaluable for long-term engine health.

Suspension and Handling Enhancements

The Challenger Redeye is a heavy car—nearly 4,500 pounds—and stock suspension prioritizes ride comfort over cornering grip. Upgraded components can dramatically improve turn-in response, reduce body roll, and help put power down to the ground.

Lowering Springs and Coilovers

Lowering the center of gravity is one of the best handling upgrades. Eibach Pro-Kit or H&R Sport Springs lower the Redeye by 1–1.5 inches while maintaining decent ride quality. For adjustable damping and ride height, KW V3 or Bilstein B16 coilovers allow fine-tuning for street or track use. Many owners report that a 1-inch drop reduces body roll by more than 30% and improves weight transfer during hard launches.

Strut Braces and Chassis Rigidity

Without reinforcement, the unibody chassis can flex under high loads, especially with sticky tires. A front strut tower brace (e.g., BMR Fabrication or Steeda) ties the shock towers together, sharpening steering feel and reducing cowl shake. A rear chassis brace, such as the Dodge Performance Stage 3 brace, further stiffens the rear subframe, helping to prevent wheel hop during aggressive launches.

Upgraded Dampers and Sway Bars

Factory shocks are calibrated for a cushioned ride. Bilstein or Penske Racing shocks offer monotube designs that respond faster to bumps and maintain control at high speeds. Adding a larger front sway bar (e.g., 22mm from Hellwig) reduces body roll without sacrificing too much compliance. For drag-focused Redeyes, adjustable rear shocks (like QA1 single-adjustables) allow quicker weight transfer off the line.

Wheels, Tires, and Braking

Power is meaningless if you cannot stop or put it to the pavement. The Redeye’s factory 20-inch wheels with Pirelli P Zero tires are okay for daily driving, but dedicated performance envelopes require upgrades.

Drag Radial Tires and Lightweight Wheels

For straight-line performance, a set of Mickey Thompson ET Street R or Nitto NT05R drag radials on 15-inch or 17-inch rear wheels (e.g., Racestar or Billet Specialties) will dramatically improve 60-foot times. Many Redeye owners drop 0.3–0.5 seconds in the quarter mile simply by switching to a proper drag radial and skinnies up front. For road course enthusiasts, a set of lightweight forged wheels like Forgeline or BC Forged paired with Michelin Pilot Sport 4S tires reduces unsprung weight by 10–15 pounds per corner, improving both acceleration and braking.

Brake Upgrades

Stopping a 4,500-pound car from 150 mph requires serious braking hardware. While the Redeye comes with six-piston front calipers and 15.4-inch rotors, repeated high-speed stops can lead to fade. Upgrading to two-piece slotted rotors from Baer or StopTech reduces weight and dissipates heat more effectively. High-performance brake pads like Hawk DTC-70 or Carbotech XP12 provide consistent bite at elevated temperatures. Brake duct kits that channel air from the front fascia to the rotors are a cost-effective way to lower rotor temperatures by 100–150°F during track sessions.

Exterior and Aesthetic Upgrades

Your Redeye should look as fast as it is. While visual mods do not add horsepower, they can reduce drag, improve airflow to cooling components, and certainly turn heads.

Performance Spoilers and Aero Components

The factory spoiler is mostly cosmetic. An adjustable carbon-fiber spoiler (like the Mopar Performance Level 3 spoiler or a RennenTech rear wing) can reduce rear lift at triple-digit speeds, improving stability. A front lip spoiler (e.g., ZL1 Addons or Carbon Creations) helps channel air around the front wheels and can be paired with a belly pan for smoother underfloor airflow. These aero additions may not be necessary for street use, but for those who visit open-track events, they provide real measurable benefits.

Lighting Upgrades

LED conversion kits for headlights, fog lights, and taillights not only modernize the look but also improve nighttime visibility. Oracle Lighting offers color-shifting halos and demon eyes that integrate seamlessly with the Redeye’s lighting clusters. For brake lights, sequential turn signals from Diode Dynamics add a custom touch. Interior LED kits for footwells and door handles can create a more premium atmosphere without breaking the bank.

Vinyl Wraps and Paint Protection

A high-quality vinyl wrap (from brands like 3M or Avery Dennison) allows owners to change their car’s color completely without permanent commitment. Satin or matte finishes are particularly popular for hiding minor imperfections. For those who want to preserve factory paint, a full XPEL Ultimate Plus clear bra protects against rock chips and swirl marks. Many NashvillePerformance.com customers combine a wrap with ceramic coating (e.g., Gtechniq Crystal Serum Ultra) to reduce maintenance and keep the car looking showroom fresh.

Interior and Comfort Upgrades

While performance is king, the interior of the Challenger Redeye can be enhanced for better driver engagement and comfort.

Performance Seats and Steering Wheel

The factory seats are comfortable but lack lateral support during hard cornering. Aftermarket seats from Recaro or Bride with aftermarket brackets (e.g., Planted Technology) provide significant thigh and shoulder bolstering. A thicker steering wheel, such as a Momo 380mm or Sparco flat-bottom wheel, improves grip and gives a sportier feel. For those who keep the factory seats, a set of 4-point harnesses and a harness bar (e.g., Watson Racing) can make track days safer and more engaging.

Data Acquisition and Gauges

Monitoring vital parameters is essential when making big power. A pillar-mounted gauge pod with Autometer or Aeroforce gauges for boost pressure, wideband air/fuel ratio, and transmission temperature provides real-time feedback. For tech-savvy owners, a Racepak IQ3 dash logger can replace the factory cluster with a customizable digital display that records lap times, G-forces, and engine parameters. Many aftermarket tuners recommend a standalone wideband sensor (like Innovate Motorsports LC-2) to ensure safe tuning.

Installation and Maintenance Considerations

Upgrading a Challenger Redeye is not a simple plug-and-play affair. Proper installation and ongoing maintenance are critical to long-term reliability. NashvillePerformance.com recommends that all major modifications—supercharger pulleys, headers, suspension—be installed by a certified performance shop with experience on the platform. Additionally, after any engine modification, a dyno tune is essential to recalibrate the engine control unit (ECU). Regular oil changes with a high-quality synthetic (e.g., Amsoil Signature Series 0W-40) and upgraded spark plugs (such as NGK LFR7AIX) gapped to the tuner’s specification will help prevent misfires under high boost. It is also wise to invest in a quality catch can (like Mighty Mouse Wild Series) to reduce oil buildup in the intake tract, a common issue on direct-injected HEMI engines.
