About AEV: American Expedition Vehicles

AEV, short for American Expedition Vehicles, is an off-road engineering company based in Missoula, Montana. Founded by Dave Harriton in 1997, AEV began with modifications and conversions for the Jeep Wrangler TJ. Over the years the company grew from long-wheelbase Wrangler conversions into a full developer of parts for modern Jeep and truck platforms, with production facilities near Detroit. Today the catalog covers suspension, bumpers, skid plates, wheels, lighting, recovery gear and electronics.

Suspension Engineered for Load and Ride Quality

AEV's reputation rests heavily on suspension. The company says it first introduced OE-level suspension engineering to the aftermarket over 10 years ago, and its DualSport systems are built around balancing carrying capacity with on-road comfort. A typical AEV suspension lift kit pairs tuned shocks with progressive-rate springs; the JL DualSport RT, for example, includes frequency-tuned, triple-rate coil springs for 2.5 inches of additional front and rear ride height. Those springs are also relevant if you are replacing worn components, and AEV's coil springs are designed to restore or raise ride height while handling the weight of bumpers, winches and gear. Bump stop and spring spacer kits for Wrangler and Ram applications round out the lineup for owners who want a more modest lift.

Bumpers, Mounts and Recovery

AEV is also known for steel bumpers, skid plates and recovery equipment that work as a system. Vehicle-specific hardware such as a winch mount allows a winch to be installed cleanly on the platform it was designed for, while a spare tire carrier mount moves a heavy full-size spare off the tailgate and onto a purpose-built bumper or bracket. Differential skid plates, steering damper relocation kits and a steel-head recovery shovel reflect the same trail-first thinking.

Electronics That Keep Up With Your Build

Bigger tires and different gear ratios throw off factory calibration. AEV's ProCal line addresses this: the ProCal SNAP corrects the speedometer after larger tires (up to 42 inches tall) or axle and transfer case gear ratio changes. A programmable speedometer and odometer module like this keeps mileage, speed readings and related vehicle systems accurate after modifications.

Platforms and Fitment

While AEV is best known for the Jeep Wrangler JK, JL and Gladiator JT, its parts also support Ram trucks and, more recently, GM midsize and full-size pickups such as the Colorado, Canyon, Silverado and Sierra, including DualSport wheels. When shopping, confirm model year, wheelbase and drivetrain, since many AEV components are engineered for specific generations.

• Match suspension kits to your intended load and tire size
• Recalibrate speedometer and gearing after changing tires or axle ratios
• Pair bumpers, winch mounts and tire carriers designed to work together
