What mods to a CJ2A?

My cj2a is basically stock except for a 289 and overdrive. What should i be looking to throw in off roading wise? I want to be a decent roader, but a really hot off roader.

I say you don't put a lift on it. The real nice things about those Jeeps is that they are so nimble becuase they are so light, so they can go a lot of places. I would definetely do something about the dif's, either weld the spiders or buy a locker.

well.. there are two paths I would go

1. I would most likely keep it close to a stocker

2. If I wanted to go offroading a lot. I would do a SOA on 2.5" leaf springs. and put huge tires on it with lincoln lockers, but that would make it undrivable on the road. It would be unbeatable off road.

I would keep it a stocker and just add locking diffs just my .02

I bet you know that when you get stuck, only one tire spins and you wish that the other would spin to get you of of the mess. That is what a locker does, it makes both the tires spin at the same time. They can be expensive anywhere from $300 to $1000 per axle. The problem with some of them is they don't allow the tires to spin at different speeds when turning on pavement. When you turn the inside wheel spins slower than the outside wheel, and the locker makes the tires spin at the same time. When you turn they ratchet, chirp, and click allowing the tires to turn at different speeds which is okay if you only seldom go on road. There are also lockers out there that you can turn on and off, like Ox locker, or ARB air locker. If the Jeep is planning to be driven on road, and on snow a lot this is the right choice. If the Jeep will never be driven on road I would just weld the spider gears togeter and save yourself some money. I only touched base on lockers, and these are a lot of my opinions and a lot of people might disagree, but do a search there is plenty of info out there. Check out www.jeepsunlimited.com they have a lot of good info on their forum.

You could get along without a locker you can turn on and off if you just drive in onroad once in a while. They are much more expensive than a regular locker. It all depends on what you are looking for. Do some reaserch and try to figure out what the best solution is, these jobs are real expensive becuase you need a shop to install them, and lockers are expensive themselfes.

winches are nice, but I would always pick a locker over a winch. Think of all the places you could go with lockers. Well... you could go with a winch but it wouldn't be as much fun.

GTBoy,
Keep it simple! If your stock springs/shackles are good then don't screw with the suspension much. I fit 33" tires in the generous fenderwells of my '45 GPW without a lift. Only adjustment was to decrease the lock to lock travel slightly in order to keep the tires off the springs at full lock. Stock springs are flexy and will keep the tires on the ground in most situations. After the tires, I'd suggest a a differential swap. You are going to be limited in your choices for the Dana 41 rear and Dana 25 front axles if you in fact still have them. I'd swap in a locker (Detroit) or a tight limited slip (Power-lock) in the rear and leave the front open unless you plan on some extremely hard 4-wheeling. My '45 is stock except the tires. Flat head 4, 3-speed, and open axles with original 4.88 gears got me around off road pretty well during highschool and college. Now she sits in the garage most of the time, I play with the '73 more since I don't feel bad cutting it up/modifying it!

Won't notice in 2wd unless he doesn't have locking hubs! They didn't come stock with them back then and he may or may not have them installed. I never put a set on my '45. Besides, the strength of the stock Dana 25 front axle is questionable with a locker and V-8 power. Sounds like GTBoy is on a budget anyway and if prioritizing mods the rear diff would come first!
Where did they grow you anyway?
