Front Axles

24 Spline Heavy Duty

Designed as a direct bolt in replacement, these components are a heavy duty upgrade that substantially increases the durability of both the inner axle shaft and the CV joint.

There are several ways that the durability is increased as follows:

• The diameter of the inner axle shaft at the CV joint is increased from .885″ (32 spline) to 1.20″ (27 spline)
• Both components use an upgraded material. We use 4340 Chrome-moly steel.
• CV joints are thru hardened to a lower level instead of case hardened. This lower heat treat level increases the shock resistance of the CV joint, the major cause of catastrophic failure with stock CV joints.

In destructive testing the failure point of this kit is approximately 9000 ft/lbs. This compares to 3000 ft/lbs for the stock components. The failure point in this destructive testing is the inner axle shaft. If you want additional durability upgrade to our Stage 2 kit.

Kits fit most models of Defender 90, 110, 130, Discovery 1 & Range Rover Classic. Inquire for specifics. If the vehicle was originally equipped with ABS, we recommend using our ABS version of this kit because it is a violation of Federal law to knowingly disable a safety feature on a vehicle such as ABS. There is no loss of durability in doing so because the failure point is the inner axle. If in doubt as to the suitability for your specific application, contact us. Installation in some applications may require some modification; again contact us for this technical data.

Discovery II Heavy Duty | Part Number GBR2424D2K

Designed as a direct bolt in replacement for the Discovery 2, these components are a heavy duty upgrade that substantially increases the durability of both the inner axle shaft and the CV joint. There are several ways that the durability is increased as follows:

• The diameter of the inner axle shaft at the CV joint is increased from .885″ (32 spline) to 1.24″ (24 spline).

• Both components use an upgraded material. We use 4340 Chrome-moly steel for both the CV joint and inner axle shaft.

• Components are thru hardened to a lower level instead of being case hardened. This lower heat treat level increases the shock resistance of the CV joint, the major cause of failure with stock CV joints is shock loading commonly incurred in aggressive recreational off roading.

In destructive testing the failure point of this kit is approximately 10,000 ft/lbs. This compares to 3000 ft/lbs for the stock components.

Kit fits all Discovery 2’s. Kit does not affect the operation of ABS brakes, Electronic Traction Control or Hill Decent Control because the tone ring for these functions is located in the hub and not on the CV joint. Assembly procedure is modified, please contact us for more information.

Price: $899.95

GBR 2522

Designed as an upgraded replacement for Land Rovers that originally came equipped with the AEU 2522 or the RTC686232 spline CV joints. These include Defender 110’s and 130’s thru 1995. It was also commonly found on military Defender 90’s thru 1995 and was also retrofitted many Rovers as an upgraded component because it can be adapted to vehicles originally equipped with later or different CV joints. Some modification is required such as upgrading the differential to 24 spline and possibly drive flanges. These components are a heavy duty upgrade that substantially increases the durability of both the inner axle shaft and the CV joint. There are several ways that the durability is increased as follows:

• The diameter of the inner axle shaft at the differential is increased from .997″ (10 spline) to 1.20″ (23 spline). The diameter of the CV joint splines is also increased for applications that came with the RTC6862 .885″/32 spline CV joint (post 1988).

• Both components use an upgraded material. We use 4340 Chrome-moly steel for the CV joint and inner axle.

• Components are thru hardened to a lower level instead of case hardened. This lower heat treat level increases the shock resistance of the CV joint, the major cause of failure with stock CV joints.

In destructive testing the failure point of this kit is approximately 10,000 ft/lbs. This compares to 3000 ft/lbs for the stock components. The failure point in this destructive testing is the internal components of the CV joint. This kit is only offered as a Stage Two kit.

Kit fits Defender 90, 110, 130.  If in doubt as to the suitability for your specific application contact us. Installation in some applications may require some modification, again contact us for this technical data.

Available as special order.

 

Rear Axles

Heavy Duty 24 spline

Designed as either a direct bolt in replacement for existing 24 spline applications or as an upgrade from earlier 10 spline applications. This axle kit is fully compatable with stock alloy wheels. It is a heavy duty upgrade that substantially increases the durability of the rear axle shafts. Features of these shafts are as follows:

• These shafts utilize a true “waisted” design. This specific waisted design is proprietary to us, utilizing extensive in house research and development. Waisting is also on the flange end of the shaft, so in the advent of breakage, field repairs are much less time consuming.

• Rolled spines – rolling splines cold forges them resulting in an increase in durability in the range of 30 to 35%. We are the only manufacturer suppling this feature for upgraded Land Rover axle shafts

• These shafts use an upgraded alloy steel. We use 4340 chromemoly steel. This steel is superior to either stock axles that are made from a commercial grade case hardening steel. Shafts are induction hardened to a higher lever than stock shafts or competing HD aftermarket shafts, significantly increasing their tensile strength and durability.

Kit includes two axle shafts, two drive flanges, two snap rings and the sealing caps, plus we assemble the entire units for you so all you do is install them.

If in doubt as to the suitability for your specific application contact us. Installation in some applications may require some modification such as changing the spline count of the differential, again contact us for this technical data.

 


Defender 110/130 One Piece Expedition Shafts

Designed as an upgrade for either stock 10 & 24 spline applications or our 24 spline heavy duty rear axle kit. This axle kit is fully compatible with any Land Rover wheel including alloy wheels. The huge advantage of these shafts is the drive flange is integral with the axle shaft so this eliminates the spline wear problem rampant in post 1993 Defenders that never were equipped with one piece axle shafts yet have are equipped with a dry hub. You don’t want to be half way around the world and be sidelined with stripped drive flanges. This happens to every Defender in existence unless you regularly check and replace them. These axles are an absolute must for any Defender 110 or 130 and far superior to any other rear axle kit on the market.

Available soon for both Salisbury (1994 thru 2001) and P38 (2002 thru 2015) rear axle equipped Defenders.

If in doubt as to the suitability for your specific application contact us. Again contact us for this technical data.
