    Re-gearing and suspension Advice please

    Yes I am definitely going for it. Unless there is something really wrong that I don't know about but I thought you said yourself that you drove a 6in lift KJ and it was fine so do you think the JBA 4in Y link will be enough for a 2in cradle drop please ?

    Re-gearing and suspension Advice please

    Ok thanks Tom I thought 1 inch was sufficient. So do you think my JBA 4in Y Link fitted above the rear Diff will be low enough for a 2 in cradle drop?

    Gear ratio

    Thanks Tom that starts to make sense now. So do you think this is not too much trouble to fit the 4.88? I won't be doing the job myself but I was worried to start telling the guy who will do it that the gear and pinion would not fit in the differential without grinding the teeth.

    Could you explain please Tom I was lead to believe that 1/2 inch had to go from the inner cup.

    Gear ratio

    The 8.25 in any year of the KJ,and KK,uses the same gears so be it a '02 KJ with the 8.25 or a '12 KK with the 8.25 you can regear to 4.56's.There are 4.88's out there but you must grind down some of the ring gears teeth to get the center pin back in. Hi TJKJ, I don't want to be a pain in the...

    No more than 1/2 inch of ground clearance gain? Do you mean the cradle has got to be lowered of 1 and 1/2 inches then?

    Shaved CV's

    I am going to have my CVs machined by a local guy here in UK. He asked me me a couple of questions to which I was not able to reply so please TJKJ or any of you guys who have the knowledge your help here would be greatly appreciated. So here it goes: I understand that the inner cup of the CV...

    Re-gearing and suspension Advice please

    Thanks for this Tom I really appreciate your advice. Cost wise apart from the steel diff there isn't much difference. I lack a bit of information about what needs to be done on the CVs, I mean precisely where and how much has to go. But apart from that I believe it's a matter of lowering the...

    Re-gearing and suspension Advice please

    Reposted this thread as it was probably in the wrong place. I was seriously thinking to go up to 6in of lift but I found a post from a guy (he will recognize himself if he reads this but it wouldn't be right to give his name without his agreement) who was wheeling with the JBA 6in for a while...

    I was seriously thinking to go up to 6in of lift but I found a post from a guy (he will recognize himself if he reads this but it wouldn't be right to give his name without his agreement) who was wheeling with the JBA 6in for a while and now goes SFA because he has encountered too much problem...

    Of course not as much as what I currently run... Bloody Hell !!! Very impressive !!! I couldn't see these pictures last night as I was using the computer at work. It allows me to log in sites like this but its Censorship doesn't download pictures. This is mad to have so much suspension...

    Gear ratio

    At the 23" mark you can run 265/75R16's on a 16x7 rim with 4" of back spacing and have very little rub and get some mad flex. Yes bear in mind I have a CRD so the first thing if I want to go above 22" would be to get my CVs machined. If only I knew what needs to be done to the CVs I know...

    Gear ratio

    Thanks Tom, Great pic this one !! I can tell the difference of lift between the two but it's difficult to tell the difference of tyre size. Maybe yours seem a little bit narrower as I suppose you are on 32x11.50 and he is on 33x12.50. Anyway yes I am going to seriously think about this as...

    Gear ratio

    Thanks again man. You've enlightened me on that particular subject. Not that I believe in Santa anymore but there are guys on Facebook with KJ who say they ride on 33"s and their lift doesn't seem to be much higher than mine so that used to bug me. I suppose all depends how they use their...

    Gear ratio

    Any idea about the effect of 4.10 ratio with 31"s tyres for the NSG370 6-speed overdrive manual transmission ? As it's what I've got fitted on my 2.8CRD.

    Gear ratio

    Thanks TJKJ, Now that makes sense !! And I am glad to know that I could go up to 4.56 ratio in my own diff. I was going to have an ARB Air locker fitted in the rear so I thought I might as well re-gear. The big dilemma I have now is that I am only at 22" between wheel hub and fender at front...

    Yes that's really amazing as they are THE Specialist. And they supply 2 different pictures of 8.25" Differentials. If we can't rely of what Yukon says about differentials ..... who can we trust?

    Gear ratio

    Thanks for the info about the JBA steel diff it seems that is the only way to fit 4.56 ratio with an IFS then. I am now in the Yukon website and they show 2 models of Chrysler 8.25". The one used on Liberty 2005 to 2013 (C213R/C213RE) they make only one Ring & pinion gear set in a 3.55...
