Out back is a Dana 70HD axle that was pirated from a dualie truck. Like the front axle it has 4.56:1 ratio gears and a Riddler Manufacturing diff cover. It has been fit with a Detroit Locker to ensure power is sent to both wheels. The rear suspension includes Pro Comp 56-inch-long Chevy-application leaf springs, Willys Jeep Parts 3-inch shackles, and repositioned Bilstein 5100 series shocks. Power is delivered to both of the truck’s axles via heavy-duty driveshafts from Drive Line Service in Colorado Springs.
