Vehicle Details
This 2008 Dodge Challenger SRT8 was modified over several years by Modern Muscle of Plainfield, Illinois, and is powered by a supercharged 426ci Stroker V8 mated to an RPM Transmissions Level V 4L80E automatic transmission and a 9? rear axle. Equipment includes a 4.2-liter Kenne Bell Mammoth Root supercharger, Apache cylinder heads, a Holley Dominator ECU, water and methanol injection kit, Mishimoto aluminum radiator, B&M Supercooler, Borla exhaust, and Chromoly 3.5? driveshaft. BC Racing adjustable coilovers, Hotchkis Sport sway bars, and 20? wheels are also fitted, while the interior is equipped with an RPM roll cage and harnesses, a Holley 12? LCD instrument panel, a Kenwood touchscreen head unit, a trunk-mounted subwoofer, and Dark Slate Gray leather and microsuede upholstery. This Challenger SRT8 was acquired in 2023 and is now offered with modification records, manufacturer’s literature, two key fobs, a clean Carfax report, and a clean Illinois title.
The car is finished in Brilliant Silver Metallic (PS2) with black carbon-fiber-look hood stripes and a black SRT-branded rear spoiler with an integrated backup camera. Additional equipment includes HID headlights, a sunroof, LED daytime running lights, and fog lights.
Black-finished 20? Hellcat wheels are mounted with 275/40 Continental ExtremeContact tires, and braking is provided by slotted discs with red-painted Brembo calipers at all four corners. Suspension modifications include BC Racing BR adjustable coilovers and damping extensions, a Hotchkis Sport sway bar set, and Speedlogix subframe connectors.
The heated front bucket seats are trimmed in Dark Slate Gray leather with microsuede inserts and equipped with RPM five-point harnesses. An RPM eight-point roll cage is installed, and additional appointments include a B&M Quicksilver shifter, power-adjustable driver’s seat, air conditioning, cruise control, a Kenwood touchscreen head unit, and a trunk-mounted subwoofer.
The four-spoke multifunction steering wheel frames a Holley 12? LCD instrument panel featuring a 160-mph speedometer, a tachometer with a 7k-rpm redline, and gauges for boost, fuel, and oil pressures as well as coolant temperature and fuel level. The digital odometer shows 404 miles, which is said to represent the number of miles traveled since the completion of the modifications. True mileage is unknown.
