Want a Dodge Charger LX chasses conversion that represents what a four door sedan dedicated drag would look like? Then we have something for you!

We took the speed of the DRAG PAK Challenger, and adapted it to the cheaper LX sedan chassis. Why? Because they won't do it. But we know Charger customers...and we know you love them just as much if not more than a coupe. More doors, more scores!

Our FOURPAK Roller represents Drag Pak technology in the architecture of a sedan, and is available as a rolling chassis designed for the up and coming NMCA Sealed 392 Crate Motor Class, and Modern Street HEMI Shootout Pro and SuperPro Classes.  Available in three configurations and many HIPO Colors.

Many Options available. We can use 2005-2022 Chargers. The cost of the core car can be had for less that $2k these days...and most are RUST free.

These models are built from select 2011-2021 SE, SXT, and R/T Dodge Charger models from used market inventory. We don't cut up Hellcats!

At Ready Chassis, we pride ourselves on finding and building our stockpile from the best-used cores we can find on the market. Low Mileage, salt-free cores taken from the dry West and Southern United States climates.

Each car is hand-selected, disassembled, and then converted into killer door slammers, when then get the NHRA approval before delivery to the customer.

Whenever possible, we acquire our cars in the colors the factory offered - and we target cars that are HIPO colors that look really good on race cars. 

We then disassemble each car, inspect and repair any exterior areas that are in need (scratches, paint chips) and we then wrap the cars in a protective wrap so that they can enter the process to be converted into factory supercars. 

There are two levels of the Charger Model FOURPAK conversion that we are offering today
