GKN Overdrive for Defender

Brid

4WD Monthly No. 72 (November 2004) had a multi-page article on the GKN unit. It seems to be a pretty robust system and would be something I'd fit (even at nearly $4k) if the cabin noise was getting to me and I wanted to save a litre and a half per hundred kays. The exhaust has to be cut and shut on a 90, but it fits up easily to a 110 or 130 without modifying anything else.

Being electronically controlled, I guess it also a case of just something else to go wrong....but they seem to be very reliable to date

Bruce Davis is the distributor over here on 02 9679 1179

Funny I should be reading this 5 minutes after talking to Bruce hmself to see if I could take a 110 with this unit already fitted for a test drive. I do about a thousand kays nearly every weekend to get to our property and back. Apart from the noise reduction, I'd also like to see 8.5L/100km from my 160L fuel tank. :)

Hi Brid.

Have been told the disco transfer case is the same gearing as GKN unit. Only what I've been told though, It could be another option. Have the same problem with my tdi 130 tray back, the speedo is 5km fast as well on mine gets a bit frustrating on the long runs. Hard to find someone thats changed the gearing on a standard defender, and run around for a couple of years.

Cheers axle
