4 of 5
The rear axle is the venerable Corporate 14-bolt with 4.56 gears, a welded differential, and a host of upgrades from Great Lakes Off Road, including the company’s bombproof diff cover, pinion guard, and disc brake conversion. The rear suspension uses 63-inch-long Chevy springs that provide plenty of articulation while resisting axlewrap. Flipped shackles and 2 1⁄2-inch lift blocks match the rear ride height to the front, and fender trimming makes up the remainder of the room necessary for the big meats.
