Re: Which design for drive shaft spacer? 4 or 8 hole?
</font><blockquote><font class="small">In reply to:</font><hr />
thanks for all your answers. The reason for a 1 1/4" spacer is that I want to compensate that I moved the front axle forward. I need to clear the oil pan of an European Kick's 2.0l V6. I addition I have 2" lift.
I am planning to run stock axles and drive shafts until something breaks and/or I am fabbing a new suspension.
I do not want to buy a spacer as I thik fabbing your own stuff is fun.
Did you ever have bad experiences with the following design: 8 holes, threads in the spacer, aluminum material? Will the engine torque pull any threads in an aluminum spacer?

If you are doing straight through holes(SPACER) just to acomidate longer stock shaft you should not have a problem with strength, allthough you also put the joint in a better position to bind, depending on how far you move the front axle. As far as your ?? on Aluminum and threads there is only one person that is threading aluminum for a shaft (adapter) that I know off and thats me and it is patent. I do not know of 1 failure do to rotationl torque on 1 of mine as of yet. The material is 6061 and the threads are rolled instead of tapped (30%) stronger thread over the conventional tap. The standard dimension on them is 1/2" thick I have made a few special runs of 3/4" for a few people. The only reason you would thread would be to accomidate a larger flange shaft then what is physicaly larger then the t-case or pinion flange other wise just drill straight through. Most kits with a 4-5" lift use two 1/2" in the rear and a 3/4" in the front I ran that on my zuk with YJ's and 5.5" sproa with out any problems. I didnt have a prob until I went S/R then I just fabbed a longer shaft and dumped the spacer. Hope this helps some Last I would not make an a spacer 1-1/4" thick and tap it for both sides, straight drill it and you should be fine. And yes fabbing stuff you self is great the only reason I started doing this was to get a larger shaft on a zuk, I did alot of hunting and pecking around for info and no other vender at the time seamed to be interested in the design. So I ran with it and the customer base speaks for itself.. What ever you do remember one thing KIS keep it simple and it shoud work
