Land Rover Half shafts

Most Land Rover & Range Rover Types made. New 110 1994. ( Not S111 at present - 2006 )

Strengthened KAM Diffs Half Shafts.

We use a far better steel than the original shaft and also use a more controlled heat treatment in the production of the KAM shafts. This combination gives the KAM shafts a better flexibility and about 40% increases in strength. We have very little breakages of our shafts and they are considerably better priced than our competitors. The KAM shaft have been used for the last 14 years in many trial and competition vehicles world wide. We have also recently made a batch for the military for the PS10 and have performed well in tests and have won a contract to supply our specification shaft with our new diff locker system. Initially the supply was for 750 diff locker and 1500 shafts for Jan to April 2005. We are now supplying 1100 more lockers and 2400 shafts.

These shaft are identical to the KAM Land Rover ones apart from the length. i.e.; 24 splines and 31.47mm dia.

New KAM Aerospace Steel Specification Shafts

With the increase use of larger diameter tyres and challenge competitions word wide KAM are have been requested buy a number of distributors to offer a aerospace steel specification half shaft. The original KAM strengthened shafts perform well and have a long history of success but we feel that to offer an option to customers would benefit sales. We are currently working on these new shafts and hope to informed distributor in the next 8 weeks when they will be available.

KAM Strengthened Shafts Front

They are 24 splines on the diff end and 23 splines on the CV end. If you have a newer vehicle 1889> then you may have 32 splined CV. If this is the cases then you will have to purchases a KAM CV conversion kit. The 32 splined shafts cannot be made to be very much stronger because they simply do not have the diameter that is required i.e.; 23 spline shafts are 31.69% bigger that then 32 spline one's so we do not make the shaft as a direct conversion. The same sizing problem is with the 10 spline shafts. We can supply 24 spline sun gears so you can fit our KAM shafts to your old 10 spline carrier or better still fit a KAM 4 pinion diff centre or KAM locker.

KAM Strengthened Shafts Rear.

These are made from the same high quality steel and controlled heat treatment. They are 24 splined on both ends. You may what to bear in mind that if you buy the new KAM diff locker you get the shaft with the locker kit. New locker not available until at least November 2005.

What they will fit

The rear shaft will fit all Land Rovers apart from:

101 rear, Series 1,2,3 front and rear.

We hope to be making the rear series 2 & 3 shaft again in the future, but not for the next 7 months

New 110 Rear Shafts

We have just made a batch of 110 rear shafts. There are 2 different shaft lengths. Please give lengths or original shafts.

1994> Long 957mm Short 640mm

Please Note:

1) If you have a pre 1989< Land Rover or Range Rover you may have 10 spline shafts, so you will have to change your sun gears in the diff as KAM shafts are 24 spline on the diff end.

2) If you have a pre 1986< Land Rover or Range Rover and are fitting KAM shaft to a standard Land Rover carrier, then you may have to ream (machine) out the diff carrier bearing centre so the new larger KAM 31.4mm shaft will fit. ( This is rare and is not often required even in old axle types)

Hubs Driving Members Rear

You will have to have new 24 spline hubs if you are fitting KAM rear shafts. (unless you have a V8 90)

There are 2 Hub Types:
Narrow on the newer Land Rovers about 1986>
Wide on the older ones pre 1986<
To help you choose the right ones here are the 2 widths of the hubs.
Narrow Hub 40 mm pcd 47mm ( A punch mark is required on the inner side of the hub, on the shaft, as the hub is 15mm shorter, the shaft can side out this small amount and pop the cap off.)
Wide Hub 55 mm pcd 49mm

Wide Narrow 55mm 40mm

�23 +17.5% VAT for driving member hub. You will require 2 off
