The Mopar Jeep Lower Forty is now equipped with massive 40-inch x 13.5-inch tires mounted on Mopar’s 20-inch forged-aluminum wheels. Mopar added aggressive wheels and tires to a stock, two-door Jeep Wrangler Rubicon without the use of a suspension lift. Custom front and rear fender flares are 1-inch wider and are located 4 inches higher than the stock Jeep Wrangler. A new one-piece carbon-fiber hood with a Jeep CJ-like power dome and an all-new drop-down tailgate stamped with the “Jeep” logo are added to complete the next exterior design.
Mechanical upgrades came directly out of the Mopar catalog. The Jeep Lower Forty features an all-new 5.7-liter HEMI® V-8 engine and a Getrag 238 six-speed with manual transmission. Powertrain installations were handled by Burnsville Off-Road using an AEV 5.7-liter HEMI V-8 conversion kit.
The Mopar-supplied Dana 44 front axle and a Dana 60 rear axle, fitted with 5.38 gears and ARB air lockers, were assembled by the Dynatrac and revalved Bilstein shocks maintain vehicle stability on rough terrain.
