Just got done rebuilding the dana 30/44 axles and getting ready to install. Thinking of a 1" or 2.5" lift kit. What are thoughts on upgrading the shackles? Would a cj5 lift kit fit then?

Here is a link to photos of the build http://s1370.photobucket.com/. I have been thinking about steering and exhaust. I have the steering from a 74 CJ5 I was thinking of using, it's not power but would work better than stock 2A. Anyone ever adapted the box mount to a 2A frame? Also headers versus stock manifolds any opinions?

I have a warn OD on my 60 willys and can barely do 70 but with the windshield down i can hit 75 and i have a f134. It takes me almost 3 minutes to reach 70 and with my 5.38s and 235s thats still screaming. These type of jeeps were not meant to go fast. They were used on farms hence the option of PTO to use different attachments. we had a 72in mowing deck on mine and it was used to cut the grass FWIW. There a lot of fun, dont get me wrong but they are not meant for highway speeds. I can tell you that I drove mine from hanover PA to Ocean city MD in my willys which is about 180 miles one way and back and it was scary. 4 wheel drum and manual brakes are not the best for abrupt stops just to let you know.

another vote for warn or saturn overdrive and keep stock axles. Buy a new overdrive, used ones can be troublesome and pop out of gear. I have 225 in a 2a, using a 4 blade oem type metal fan blade and a good fitting shroud. Not sure of what radiator. Cools good.

Thought about keeping the stock axles but the front pinion and ring were not shimmed properly and ate each other up. I bought a 74 CJ5 and put the Dana 30 front and 44 rear in as well as the T-14 trans and D20 T case. Just wondering about the 74s steering and how to adapt it along with if I should go with headers or stock manifolds. Also I have the stock radiator from the L134 I've heard some use it with no problems or should it be updated. Thanks, Stan

Ok, just some rambling thoughts. First, it would be very wise NOT to use the T86. They may shift better and be a bit less noisy than the T90 but they are weaker and parts are hard to find. Worst CJ three speed but slightly better than the T84 of the MB/GPW's.

Realize that the D20 is a 2:1 low range versus the 2.46 of the D18. Aftermarket gears are available for both but that is expensive. The two really big advantages of the D18 are the lower rear driveshaft angle and the overdrive option. As to gears for a 225, 488's and an overdrive work really well. If the 225 is a little built, no problem doing 75 all day. If you do stick with the 18 (and I would build it using the case from your D20) and want an overdrive, the original Warn's are better than the Saturns. The Saturns use a cheesy diecast shifter fork which break on a regular basis (Warn's use bronze and I have never had one of those break).

If I were doing this, the axles would be a front D30 and a rear D44-offset-and keep the D18. You can make a pretty decent D44 from the stock axle by putting a full float kit in it. The next best option is a flanged offset D44 from the 70 1/2-71 CJ's. You get 30 spline axles with either but the latter are hard to find.
