The 10.v" 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 Limited and GMC Savanna vans produced from 1973 to current 24-hour interval.[1] Debuting in 1973, this differential is a full floating pattern with a band gear bore of 10.five 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, simply rather 12. The 14 bolt differential is a pop axle swap choice for Jeep Wrangler owners,[2] and is referred to as the "corporate" xiv bolt because of the odd nature of GM'due south corporate construction in the 1970s.[3]

Not to be confused with the GM xiv-bolt 9 and i/two inch band gear rear differential which has c clips to retain the axles unlike a gratuitous floating axle that the heavy duty big brother utilizes. The 9 and 1/2 inch is easily identified from the ten and 1/2 inch by looking at the hub. If the hub protrudes through the center of the wheel, that indicates the more desirable ten.5 and one/2 inch full floating rear axle. The 9 and 1/two inch rear end, while durable in its own right, is mostly regarded as less desirable in loftier 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. Ssr.

General specifications [edit]

  • 10.v in (270 mm) diameter ring gear
  • Axles are thirty spline axles
  • 1.590 in (40.4 mm) diameter shank on the pinion
  • Gear ratios: 3.21, three.42, 3.73, 4.x, 4.56, four.88, v.xiii, and 5.38
  • Carrier interruption: iii.21:one - 4.11:1 and 4:56 - 5.38
  • i.5 in (38 mm) axle spline diameter
  • 1.34 in (34 mm) axle shaft bore
  • Axles are different lengths from side to side
  • Removable pinion support
  • Weight: 550 pounds (250 kg)
  • GAWR: viii,600 pounds (3,900 kg) Max.
  • Pinion supported with bearings on both sides of the teeth (straddle mountain), which minimizes pinion deflection

Pattern [edit]

The first pattern was produced from 1973 to 1984. The first design remained unchanged until 1986. This pattern had drums that were held on past the wheel studs and had a smaller diameter pinion begetting than the second design. The second design was produced from 1986 to present. 1 modify that occurred in the second design was that on some models the brake drum could be removed without having to remove the hub and beam shaft. Additionally, the pinion received a larger diameter begetting while the pinion stayed the same bore, which increased the durability of the pinion. All these axle are full floating.

Brakes [edit]

Most of the 14 bolt differentials produced through model yr 1998 were fitted with pulsate brakes,[four] but some vehicles with the 14 bolt were upgraded to disc brakes in 1999. Pulsate brakes were offered on many full size GM vans for several more years, but by 2003 all vans came with disc brakes.[five] The first design of this differential had three different bore restriction drums. At first the differential was released with drums small enough to fit 15 in (380 mm) wheels. And so later on a few years a larger drum was standard on the 3⁄iv -short-ton (0.68 t) along with the even larger drum on the 1-brusque-ton (0.91 t). This is an area of the axle associates that is commonly converted past the enthusiast to disc brakes for added braking performance and lower cost of maintenance.[6]

Pinion [edit]

The pinion is supported both in front of and behind the pinion teeth,[7] an arrangement oftentimes referred to every bit "straddle mounting". Straddle mounting greatly reduces pinion deflection under high torque loads, conferring increased longevity and torque capacity. The pinion is also removable from the back as well making for easier access.

Re-purposing [edit]

The 10.v" 14 commodities differential and axle is quite popular with Jeep Wrangler owners who want to upgrade their standard Dana 30, Dana 35, or Dana 44 axle. While the ten.5" 14 bolt axle is heavier than the standard Dana axles offered on the Wrangler, it is much stronger. This increased force allows Jeep Wrangler owners to mount upward to 44" tires without business organisation almost beam shaft breakage.[8] Many Wrangler owners volition have up to 2 inches removed from the bottom of the 10.5" 14 commodities differential housing to maximize ground clearance.[9]

Due to the popularity of GM trucks and vans, ten.5" 14 bolt axles are common in junkyards. This makes them an option for any number of vehicle customization projects, buggy builds, and even classic trucks.

xi.5 AAM [edit]

The 11.5 AAM 14 commodities rear differential began to replace the ten.5" 14 commodities in many Chevrolet Silverado and GMC Sierra trucks beginning in the 2001 model year. Nevertheless, the 10.5" 14 bolt beam continues in product today on GMC Savanna and Chevrolet Express vans. The 11.5" fourteen commodities axle is also used in tertiary Generation Dodge Ram 2500 and 3500 trucks. The GM version uses a paper gasket and the Ram version uses a re-usable rubber gasket. This aspect also makes the Dodge and GM axles appear very different, because of the dissimilar cover used. The GM AAM beam tubes are reduced to smaller diameter than the AAM Contrivance'southward at the spindle from the housing, from iv" to three.5". Newer GM trucks are congenital to the same specs as the Dodge axles. GM besides opted to have a vibration dampener installed on the yoke, while Dodge opted to place the dampener on the drive shaft. This became the standard beam on all 2500 and 3500 RAM trucks for model year 2014.

Features [edit]

  • Increased GAWR: 6,900 pounds (3,100 kg) Max.
  • 1541 alloy beam shafts
  • Larger ring and pinion than the "xiv bolt" axle. Equally well as other components.
    • Although pinion is overhung/no back up bearing like the 14 bolt.
    • Selectable locking differential on Ram Ability Carriage (2014 and newer.)

x.five AAM [edit]

2500 3rd Generation Dodge trucks utilize a 10.v AAM in all the V8 equipped trucks. Some early model Diesel fuel and V10 trucks besides used this axle. Like the 11.five, this axle likewise uses a re-usable rubber gasket and looks similar to the eleven.v axle. The Ram Power Wagon too uses this axle with a locking differential. 2013 was the last model twelvemonth that RAM 2500 and 3500 trucks were equipped with this beam.
