An anti-roll bar is an automobile suspension part that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. It links opposite front or rear wheels to a torsion spring using short lever arms for anchors. This increases the suspension's roll stiffness—its resistance to roll in turns.
A beadlock or bead lock is a mechanical device that secures the bead of a tire to the wheel of a vehicle. Tires and wheels are designed so that when the tire is inflated, the tire pressure pushes the bead of the tire against the inside of the wheel rim so that the tire stays on the wheel and the two rotate together. In situations where tire pressure is insufficient to hold the bead of the tire in place, a beadlock is needed.
The Truck, Utility, ¼-Ton, 4×4, M151 or simply M151 was the successor to the Korean War M38 and M38A1 jeep Light Utility Vehicles. The M151 had an integrated body design which offered a little more space than prior jeeps, and featured all-around independent suspension with coil springs. It has since been replaced by the larger AM General HMMWV in most utility roles in frontline use. With some M151A2 units still in U.S. military service in 1999, the M151 series achieved a longer run of service than that of the World War II/Korean War-era MB/GPW, M38, and M38A1 series combined.

The 10.5" Corporate 14 Bolt Differential is a heavy duty differential found on many 1973-2013 Chevrolet and GMC trucks and SUVs, as well as certain versions of the Cadillac Escalade. Additionally, this differential is found on Chevrolet Express and GMC Savana vans produced from 1973 to current day. Debuting in 1973, this differential is a full floating design with a ring gear diameter of 10.5 inches (270 mm). As the name implies, this differential has 14 bolts holding on the differential cover. The ring gear is not held on with 14 bolts, but rather 12. The 14 bolt differential is a popular axle swap option for Jeep Wrangler owners, and is referred to as the "corporate" 14 bolt because of the odd nature of GM's corporate structure in the 1970s.
