2006 Express3500 Ring Gear Size With 12 Bolts Cover

The 10.5" Corporate 14 Bolt Differential is a heavy duty differential plant 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 solar day.^[1] Debuting in 1973, this differential is a full floating pattern with a band gear diameter of 10.5 inches (270 mm). As the name implies, this differential has 14 bolts holding on the differential cover. The band gear is not held on with 14 bolts, simply rather 12. The 14 bolt differential is a popular axle swap selection for Jeep Wrangler owners,^[ii] and is referred to as the "corporate" 14 bolt because of the odd nature of GM'due south corporate structure in the 1970s.^[3]

Not to be confused with the GM fourteen-commodities 9 and i/2 inch ring gear rear differential which has c clips to retain the axles unlike a gratis floating axle that the heavy duty large brother utilizes. The 9 and 1/two inch is easily identified from the x and 1/2 inch by looking at the hub. If the hub protrudes through the center of the cycle, that indicates the more desirable 10.five and ane/2 inch total floating rear axle. The 9 and ane/two inch rear end, while durable in its own right, is generally regarded as less desirable in high torque applications.

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

Design [edit]

The starting time design was produced from 1973 to 1984. The commencement pattern remained unchanged until 1986. This pattern had drums that were held on past the cycle studs and had a smaller diameter pinion bearing than the 2d design. The second design was produced from 1986 to present. One change that occurred in the second pattern was that on some models the restriction pulsate could be removed without having to remove the hub and axle shaft. Additionally, the pinion received a larger diameter bearing while the pinion stayed the same diameter, which increased the durability of the pinion. All these axle are full floating.

Brakes [edit]

Most of the xiv bolt 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, but by 2003 all vans came with disc brakes.^[5] The get-go design of this differential had three different diameter brake drums. At beginning the differential was released with drums small plenty to fit 15 in (380 mm) wheels. Then after a few years a larger pulsate was standard on the 3⁄four -short-ton (0.68 t) along with the fifty-fifty larger drum on the 1-short-ton (0.91 t). This is an expanse of the axle associates that is commonly converted by the enthusiast to disc brakes for added braking performance and lower price of maintenance.^[6]

Pinion [edit]

The pinion is supported both in forepart of and behind the pinion teeth,^[7] an arrangement often referred to as "straddle mounting". Straddle mounting greatly reduces pinion deflection under high torque loads, conferring increased longevity and torque chapters. The pinion is also removable from the back likewise making for easier admission.

Re-purposing [edit]

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

Due to the popularity of GM trucks and vans, 10.5" 14 bolt axles are mutual in junkyards. This makes them an option for whatsoever number of vehicle customization projects, buggy builds, and even classic trucks.

11.five AAM [edit]

The 11.5 AAM 14 bolt rear differential began to replace the ten.v" 14 bolt in many Chevrolet Silverado and GMC Sierra trucks starting time in the 2001 model year. Yet, the 10.5" 14 bolt beam continues in production today on GMC Savanna and Chevrolet Express vans. The 11.5" 14 commodities 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 rubber gasket. This attribute also makes the Dodge and GM axles appear very different, because of the unlike cover used. The GM AAM axle tubes are reduced to smaller bore than the AAM Contrivance's at the spindle from the housing, from iv" to 3.5". Newer GM trucks are built to the aforementioned 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: half-dozen,900 pounds (three,100 kg) Max.
1541 blend beam shafts
Larger band and pinion than the "14 commodities" axle. As well equally other components.
- Although pinion is overhung/no back up bearing like the 14 commodities.
- Selectable locking differential on Ram Power Carriage (2014 and newer.)

11.viii AAM beam. Optioned on 3500 RAM trucks with the Loftier Output bundle.

10.5 AAM [edit]

2500 3rd Generation Dodge trucks use a 10.5 AAM in all the V8 equipped trucks. Some early on model Diesel and V10 trucks as well used this axle. Like the xi.5, this axle besides uses a re-usable prophylactic gasket and looks similar to the 11.5 axle. The Ram Power Wagon as well uses this axle with a locking differential. 2013 was the terminal model year that RAM 2500 and 3500 trucks were equipped with this beam.
