CJ5, a few questions.

could you guys give me fone information on cj5's what years are the best and such what changes were made etc. anyone have any good sites?

how high can i lift a cj5 before it beings to become unsafe at highway speeds?
i want to be able to do 65 and be able to turn with out tipping over,
i was thinking maby a 4inch total lift (soa) 2" packs.

how difficult is it to do a spring over axle on a cj5. if i do it will i have to convert the steering to somthing else??

what t-cases were good? trannys? did all cj5's come with the dauntless v6?

Off the shelf, I think the '72-75's were best.

D44 rear, D30 front axle. D20 xfer case.

72-75 is longer than 71 and earlier, about 4" longer in the engine compartment (pre 72 fender came down to a point where it joined the tub, 72 and later, it levels off for 4" before getting to the tub seam). This was to accomodate the AMC sixes. Makes much better for future engine swaps. 4" more wheelbase also slightly better for handling on road.

in NC, 35 years no inspection at all is required. 72 is very close to that. couple of more years, you'll save $10 per year.

No emissions either in many areas. No restrictions on motor swaps (cept in some areas, if you put in say a 2003 motor, you must meet 2003 emissions requirements.

The AMC sixes are torquey motors for the size. 258 of course much better than 232. Really wakes up with HEI ignition and Weber 32/36. You can do junkyard HEI real cheap if you look for the parts, or spend the $$ for a bolt-in online. Seven main bearnings in the sixes (one between each rod on the crankshaft) they will last forever as long as you maintain and keep oil in them.

Think of T18 swap. not terribly hard to figure out. Gain Low 1st if wide ratio trans. Autos ain't great in a 5 due to already short driveshaft lenghts.

4" lift is about the max I feel good with at freeway speeds. Last '5 I bought was a 74, had a springover on Rancho 2.5" springs, was WAY too unstable. Reversed the SOA, handling (and looks) improved 200%. I'd go maximum 4" springs, or 2.5 spings with a 1" polyurethane body lift. Looks better too...they look goofy if you go too tall.

With 2.5 or better springs, 33x12.50's are a great fit, looks balanced. If you go 35's, especially if lockered, you have go go easy on the skinny, or plan on either a D44 front or Warn heavy duty axleshafts on the D30. I've run 33x12.50's for 20 years now with no ill effects. if you go SBC or 360/etc, you can bust up a D30 easy with 35s and a front locker.

FWIW, YMMV, IANAL, ETC

soa makes it too unstable? oh well one less thing to worry about.
oh yea and another thing did all cj5's come with heat?

D18, 20, 30 were all good.

Not all came with the Dauntless just the good ones.

No, my '62 didn't even have the stock "placebo" heater in it. Just a plate blocking off the firewall.

My 75 has heat, except im in Canada so its kinda a must when it hits -30C and you only have a soft top haha. The 304 is the way to go, tons of tourqe in the mud(enough to leave patches on dry pavement with brand new 31s) and with the 2barrel the fuel economy is actually really good.

I'm a '72-'75 guy too. 2 1/2" Rancho SUA, 33's, 2" spacers in the back (Dana 44 front soon) and some fender trimming. It is stable and non-scary. The other consideration is the rear drive shaft. With a T18 I am still running a normal drive shaft (about as steep as I'd be comfortable with). I can't imagine this would be possible with a 4" lift and a T15 which means CV driveshaft ($500). For the street the T15, T150 are both good. Most will have 3.73 gearing. If your trailing I would consider a T18 upgrade.

Anything is possible if you don't know what you are talking about.

what kind of wheeling are you planning?

the inline sixes are good for torque -- they are not spinners... if you do a lot of.thick mud, a SBC or v8 AMC would prolly be better, as you need the RPM's to spin up to clear the tires.

lots of room in the engine box to work on the sixes, too, and not crowded like with an 8, so real easy to locate accessories, add-ons under the hood.

i have the 258, and do a lot of mixed wheeling. I try and avoid getting in the big mud pits just for the hell of it, as that's just not my thing, and cleanup is not my favorite.

I have had both a '72 and my '80. One thing to keep in mind when considering the CJ5... the 72-75 series shares alot of parts with the 76 and later jeeps, but some parts are a real bear to locate. In addition, many accessories made for CJ5's are targeted at the 76 and later bodys and differ greatly because of subtle changes such as the windshield design, wiper motor locations, tub design,... etc....

Not saying don't get one, just saying be aware you may have a few junkyard trips in store for you if you need parts.

Have you bought a CJ5? And asking questions about it? Or are you looking to buy a CJ? If your looking to buy there are a couple other option. For the best CJ ever built I'd have to go with a late model 86 CJ7. They come with 258, t176, dana 300, dana 44 rear, and a 30 front. Plus they are wide trac axles.

In your initial statement your said you wanted 4"lift and 33's. This is the extreme max for a CJ5 on stock axles. If you change to wide trac axles you can go a little higher. As for SOA on a CJ5 NEVER IN A MILLION YEARS. The Jeep is too short and narrow.

If you step up to a CJ7 the SOA is more of an option however don't think for 1 second that a SOA is cheaper than a SUA lift. And for highway driving I'd stay away from a SOA. Too many hassles with steering and proper caster.

86 CJ7, 258, t18, D300, D44's 4.56's, Detroit front, Warn shafts and CTM joints, spool rear, SOA, SRS, waggy springs, 6 point cage, Warn winch, 38" Tsl, Allied beadlocks.

more to think about re: years...don't know when they went computer or ignition controller and all...but one less non-repairable part to fail at the worst possible time, especially if you like to get wet.

the 72-75's (the years I am most familiar with) get super-simple if you upgrade/convert to 1 wire HEI and a 1 wire GM alternator -- get rid of the voltage regulator, etc. Worse case, fire/meltdown under dash...easy trail repair to wire direct and get home. BTDT.

72-75 come with most of the "good" stuff that most of us Early CJ-5 owners want from an Intermediate/Late CJ-5.

11" self adjusting drums and Sagninaw mainly and still retain a good bit of the classic look.

Unless you just really like the odd fire V6, which I do, I'd go for an Intermediate if it strikes your fancy. An intermediate CJ-6 w/ a 304 would be the cat's meow IMO.
