    Default Limited Slip Diffs

    Just been reading an interesting thread from Petri regarding traction aids, and their applications and benefits.

    In the course of that, mention was made of fitting LSD into the front and rear axles of a Defender. I have read that Ashcroft in the UK do these as well as a couple of other companies.

    A significant amount of my work takes me off road, predominantly on worn and washed out rural gravel roads, often with steep river low level bridges and departures, and the corresponding cross axles with ridges and ruts and mitre drains.

    Often I am heavily loaded with staff and or tools and equipment, which does compromise the 'momentum' approach to things. I rarely run out of articulation, but it does get close on occasion.

    The question on this thread is to find out from fellow Defender owners

    a) who has fitted LSD's as opposed to full lockers
    b) what are experiences in an African environment

    Thanks for the feedback

    I fitted an Ashcroft ATB in the rear of my 90.

    Makes a *world* of difference on gravel roads, it is way more stable.

    Off-road it also helps, but hard to tell how much, although the TC doesn't kick in as often as previously.

    In some crossaxle situations, I now apply less throttle to get through.

    I've got Ashcroft ATB front and back in my Disco 1, Center ATB in my 90 and Locker in my 110DC. All Ashcroft.

    I haven't tested the Disco 1 offroad yet with them so can't report back but for an overlander I reckon it's the way to go but nothing beats full lockers.

    The LT230 on the 90 is nice for reducing backlash but haven't noticed much difference if I'm honest.

    The best improvement offroad will come with a rear locker, end of story.

    I had ARB lockers front and rear in a TD5 HardTop.

    was awesome and SEEMED to me better in the hard stuff than limited slip .

    but thats just my 'feeling'


    Ive still got the whole ARB setup and it going into my wife's 'new' TDi 90.

    I have Ashcroft LSDs’ (ATBs’ to use the correct term) back and front on my TD5 90. The car is my daily driver with a 50/50 mix of on road and off road. I don’t often end up in severe cross axle situations but do drive up and down steep sandy or muddy gradients. The car is way more capable on the steep stuff and care-free on the road.

    An Ashcroft ATB would make any Defender or Disco without TC a pleasure off-road.

    For loose traction surfaces yes, like sand, wet grass etc but when you have tyres coming off the ground then locker.

    ATB will get by on axle twisters but you will need some left foot braking to assist it, it will be nowhere near as effortless as a locker tho.

    I installed the ATBs on my Disco 1 because I rebuilt the car and plan to use it for my tiger fishing trips and to Mozam which is mainly sand tracks, there they will be perfect in my opinion and better than full lockers.

    Indeed, this is why it's so effective on the Puma - the traction control does all the left-foot braking for you

    Many thanks for all the responses. I'm keen to give these a go, are there any available for sale in SA, or should I be looking to bring them in from the UK?

    If you have a salisbury rear diff it might also be cheaper to have a look at importing from the US.

    Nope, these are more expensive by a long shot. Well, at least from the agent I spoke to.

    Mine wasn't expensive and I've got it on 3 of my Land Rovers.

    Each to their own though but his profile says based in Harare, I would rather buy direct and given their service it is a pleasure to deal with Dave and his team.

    yeah, not saying anything against Dave or Ashcroft, just did some sums and the price you see on the site is not the same as the price you'll end up paying. but if in Zim, not sure what the import duties, etc. is like.

    BTW - what is your version of 'wasn't expensive'?

    Thanks for all the info guys.

    Life been a bit hectic so haven't been on this forum much...

    I will check the pricing, as I have funds (and daughters) in the UK to link with Ashcroft, but we also often bring equipment in from Cape Town, so I can link that as well...

    Going to be some tradeoff on pricing I guess.
