1996 Gmc Sierra 1500 4x4 Rear Axle 373 Gears

The 10.5" Corporate 14 Commodities Differential is a heavy duty differential found on many 1973-2013 Chevrolet and GMC trucks and SUVs, equally well as certain versions of the Cadillac Escalade. Additionally, this differential is constitute on Chevrolet Express and GMC Savanna vans produced from 1973 to electric current day.^[1] Debuting in 1973, this differential is a total floating design with a ring gear bore of ten.5 inches (270 mm). As the proper 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 beam swap selection for Jeep Wrangler owners,^[two] and is referred to as the "corporate" 14 commodities because of the odd nature of GM'southward corporate structure in the 1970s.^[3]

Non to be confused with the GM fourteen-commodities ix and i/2 inch band gear rear differential which has c clips to retain the axles unlike a free floating axle that the heavy duty large brother utilizes. The 9 and 1/2 inch is easily identified from the 10 and 1/ii inch by looking at the hub. If the hub protrudes through the middle of the cycle, that indicates the more desirable 10.5 and ane/2 inch full floating rear axle. The ix and i/2 inch rear end, while durable in its own right, is more often than not regarded every bit less desirable in high torque applications.

          The 9-1/2 c clip rear was in both the Suburban and pickups in both half dozen or 8 lug varieties.   33 spline axles.  and which was in product through 2009 and even available on a trailblazer SS, SAAB 97x. Ssr.        

General specifications [edit]

• ten.5 in (270 mm) bore band gear
• Axles are 30 spline axles
• one.590 in (40.iv mm) bore shank on the pinion
• Gear ratios: iii.21, 3.42, 3.73, 4.10, four.56, iv.88, 5.xiii, and 5.38
• Carrier interruption: iii.21:i - iv.11:one and 4:56 - 5.38
• 1.5 in (38 mm) beam spline diameter
• one.34 in (34 mm) axle shaft bore
• Axles are different lengths from side to side
• Removable pinion back up
• Weight: 550 pounds (250 kg)
• GAWR: 8,600 pounds (3,900 kg) Max.
• Pinion supported with bearings on both sides of the teeth (straddle mount), which minimizes pinion deflection

Design [edit]

The start design was produced from 1973 to 1984. The get-go design remained unchanged until 1986. This blueprint had drums that were held on by the wheel studs and had a smaller diameter pinion bearing than the 2nd design. The 2nd design was produced from 1986 to present. One change that occurred in the second blueprint was that on some models the brake drum could be removed without having to remove the hub and axle 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 commodities differentials produced through model year 1998 were fitted with drum brakes,^[4] but some vehicles with the 14 bolt were upgraded to disc brakes in 1999. Drum brakes were offered on many full size GM vans for several more years, only past 2003 all vans came with disc brakes.^[v] The first design of this differential had three different diameter brake drums. At kickoff the differential was released with drums small enough to fit 15 in (380 mm) wheels. Then after a few years a larger pulsate was standard on the 3⁄iv -brusque-ton (0.68 t) along with the even larger pulsate on the 1-brusque-ton (0.91 t). This is an surface area of the beam assembly that is normally converted by the enthusiast to disc brakes for added braking functioning and lower cost of maintenance.^[6]

Pinion [edit]

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

Re-purposing [edit]

The 10.5" 14 bolt differential and axle is quite pop with Jeep Wrangler owners who want to upgrade their standard Dana 30, Dana 35, or Dana 44 beam. While the ten.5" 14 bolt beam is heavier than the standard Dana axles offered on the Wrangler, it is much stronger. This increased force allows Jeep Wrangler owners to mountain upward to 44" tires without concern about beam shaft breakage.^[eight] Many Wrangler owners will have upwards to 2 inches removed from the lesser of the 10.5" xiv bolt differential housing to maximize ground clearance.^[9]

Due to the popularity of GM trucks and vans, 10.5" fourteen bolt axles are common in junkyards. This makes them an option for any number of vehicle customization projects, buggy builds, and fifty-fifty classic trucks.

xi.5 AAM [edit]

The 11.5 AAM xiv bolt rear differential began to replace the 10.five" 14 bolt in many Chevrolet Silverado and GMC Sierra trucks beginning in the 2001 model year. Notwithstanding, the 10.v" 14 bolt beam continues in production today on GMC Savanna and Chevrolet Limited vans. The 11.5" xiv bolt axle is besides used in 3rd Generation Dodge Ram 2500 and 3500 trucks. The GM version uses a paper gasket and the Ram version uses a re-usable safety gasket. This attribute as well makes the Dodge and GM axles appear very different, because of the dissimilar encompass used. The GM AAM beam tubes are reduced to smaller diameter than the AAM Dodge'south at the spindle from the housing, from 4" to 3.5". Newer GM trucks are built to the aforementioned specs equally the Dodge axles. GM likewise opted to have a vibration dampener installed on the yoke, while Contrivance opted to place the dampener on the drive shaft. This became the standard axle on all 2500 and 3500 RAM trucks for model year 2014.

Features [edit]

• Increased GAWR: vi,900 pounds (3,100 kg) Max.
• 1541 alloy axle shafts
• Larger ring and pinion than the "fourteen commodities" axle. Likewise as other components.
  • Although pinion is overhung/no support bearing like the fourteen bolt.
  • Selectable locking differential on Ram Power Wagon (2014 and newer.)

10.5 AAM [edit]

2500 third Generation Contrivance trucks utilise a 10.five AAM in all the V8 equipped trucks. Some early model Diesel fuel and V10 trucks also used this beam. Similar the eleven.5, this axle as well uses a re-usable rubber gasket and looks similar to the xi.5 axle. The Ram Power Wagon likewise uses this beam with a locking differential. 2013 was the last model year that RAM 2500 and 3500 trucks were equipped with this axle.
