10.5" Corporate 14 Bolt Differential

rdf:langString 10.5" Corporate 14 Bolt Differential

rdf:langString 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. Not to be confused with the GM 14-bolt 9 and 1/2 inch ring gear rear differential which has c clips to retain the axles unlike a free floating axle that the heavy duty big brother utilizes. The 9 and 1/2 inch is easily identified from the 10 and 1/2 inch by looking at the hub. If the hub protrudes through the center of the wheel, that indicates the more desirable 10.5 and 1/2 inch full floating rear axle. The 9 and 1/2 inch rear end, while durable in its own right, is generally regarded as less desirable in high torque applications. The 9-1/2 c clip rear was in both the Suburban and pickups in both 6 or 8 lug varieties. 33 spline axles. and which was in production through 2009 and even available on a trailblazer SS, SAAB 97x.
