Gm 10 1/2 14 Bolt Max Lock Lockerã¢â€žâ¢ Reviews

The 10.v" Corporate 14 Bolt Differential is a heavy duty differential found on many 1973-2013 Chevrolet and GMC trucks and SUVs, besides as certain versions of the Cadillac Escalade. Additionally, this differential is institute on Chevrolet Express and GMC Savanna vans produced from 1973 to current mean solar day.^[ane] Debuting in 1973, this differential is a full floating blueprint with a ring gear diameter of 10.5 inches (270 mm). As the proper name implies, this differential has fourteen bolts belongings on the differential cover. The ring gear is non held on with fourteen bolts, but rather 12. The 14 bolt differential is a popular axle swap selection for Jeep Wrangler owners,^[two] and is referred to as the "corporate" fourteen bolt because of the odd nature of GM's corporate structure in the 1970s.^[iii]

Not to exist confused with the GM xiv-bolt 9 and ane/2 inch ring gear rear differential which has c clips to retain the axles dissimilar a costless floating axle that the heavy duty big brother utilizes. The nine and 1/ii inch is easily identified from the 10 and 1/2 inch by looking at the hub. If the hub protrudes through the heart of the wheel, that indicates the more desirable ten.5 and 1/2 inch full floating rear axle. The 9 and 1/two inch rear end, while durable in its own right, is generally regarded as less desirable in high torque applications.

          The 9-ane/two 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]

• x.5 in (270 mm) diameter ring gear
• Axles are xxx spline axles
• 1.590 in (40.4 mm) diameter shank on the pinion
• Gear ratios: three.21, three.42, 3.73, iv.ten, 4.56, 4.88, five.thirteen, and 5.38
• Carrier break: 3.21:1 - iv.eleven:1 and 4:56 - 5.38
• 1.5 in (38 mm) axle spline diameter
• 1.34 in (34 mm) axle shaft diameter
• Axles are unlike lengths from side to side
• Removable pinion support
• 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

Pattern [edit]

The first design was produced from 1973 to 1984. The first blueprint 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 second design. The second pattern was produced from 1986 to present. One change that occurred in the second blueprint was that on some models the brake pulsate could exist removed without having to remove the hub and beam shaft. Additionally, the pinion received a larger bore bearing while the pinion stayed the same diameter, which increased the durability of the pinion. All these axle are total floating.

Brakes [edit]

Most of the 14 bolt differentials produced through model yr 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 by 2003 all vans came with disc brakes.^[5] The first design of this differential had three unlike bore brake drums. At first the differential was released with drums modest enough to fit xv in (380 mm) wheels. And then after a few years a larger drum was standard on the 3⁄four -brusque-ton (0.68 t) along with the even larger drum on the 1-curt-ton (0.91 t). This is an area of the beam assembly that is usually converted by the enthusiast to disc brakes for added braking operation and lower cost of maintenance.^[half-dozen]

Pinion [edit]

The pinion is supported both in front of and behind the pinion teeth,^[7] an arrangement often referred to as "straddle mounting". Straddle mounting greatly reduces pinion deflection under loftier 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 x.five" 14 commodities differential and axle is quite popular with Jeep Wrangler owners who want to upgrade their standard Dana xxx, Dana 35, or Dana 44 beam. While the 10.5" 14 commodities axle is heavier than the standard Dana axles offered on the Wrangler, it is much stronger. This increased strength allows Jeep Wrangler owners to mountain up to 44" tires without business organisation about axle shaft breakage.^[viii] Many Wrangler owners volition accept up to 2 inches removed from the lesser of the 10.five" 14 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 even classic trucks.

xi.five AAM [edit]

The eleven.5 AAM 14 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. However, the 10.5" fourteen commodities axle continues in production today on GMC Savanna and Chevrolet Express vans. The eleven.5" xiv commodities axle is as well 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 dissimilar cover used. The GM AAM beam tubes are reduced to smaller diameter than the AAM Contrivance's at the spindle from the housing, from 4" to 3.5". Newer GM trucks are built to the same specs as the Dodge axles. GM too 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 axle on all 2500 and 3500 RAM trucks for model year 2014.

Features [edit]

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

10.5 AAM [edit]

2500 3rd Generation Dodge trucks use a 10.5 AAM in all the V8 equipped trucks. Some early model Diesel and V10 trucks also used this axle. Like the eleven.five, this axle also uses a re-usable rubber gasket and looks similar to the eleven.5 axle. The Ram Ability Wagon as well uses this axle with a locking differential. 2013 was the concluding model twelvemonth that RAM 2500 and 3500 trucks were equipped with this beam.
