4\" CJ-7 Lift question

I've got an '83 CJ-7 with a TF999 trans/ d-300 t-case/ d-30/ amc 20. (all stock). I want to put a 4" spring lift on it and have already decided to have a CV type rear drive shaft made. My question is, do I have to do anything with the front drive shaft, or is it long enough for the application? Do I have to have a CV joint type shaft made for the front as well as the rear? Will the front shaft clear the t-case skid plate, or does the skid plate have to be modified as well? I really don't want any drivetrain vibration, so if vibration is inevitable with a 4" lift, I will just go with a 2" lift. Thanks for info in advance!

Mike, you won't need a CV front driveshaft. It's long enough so you don't have to do that. With a 4" lift you will probably need a longer
front driveshaft though. A friend has a 4" lift and there is no interference with the t-case skidplate.

Re: 4\" CJ-7 Lift question

Hey man, I have a 79 Cj7 with a 4 inch lift and i have no problems fornt or rear. I am good friends with the boys at my local 4 Wheel Parts Wholesalers so they keep me upo on what i need to do. You really do not need a front or a rear. I do some crazy stuff and no bad news. My buddy at 4WPW has a 5 inch lift with 35's and no problems either.. Good luck.....matt

What you WILL need is longer brake lines. Driveshafts OK, but you may want to go CV in the rear, pretty steep angle.

My CJ8 has a 4 inch lift. It's all stock with no problems. I do, however, have a longer driveshaft up front.

Re: 4\" CJ-7 Lift question

Thanks guys, I will plan on a rear CV shaft, I'll wait until its done to decide whether or not to lengthen the front shaft. I know about the brake lines and I will also be putting a drop pitman arm on to correct the steering. Bumpstops will have to be longer as well, I don't want the 33's hitting anything under full flex. Thanks for all the info. A person would go broke trying to buy all this information./wwwthreads_images/icons/smile.gif
