Rebuild kits for the 4.0

I know this is for an XJ....but this is a more knowledgeable board. I was going to go with the stroker...but the wife decided that me driving the suburban 50 plus miles a day would not be an option for long (Gas prices). So I have to buy a lift kit and a rebuild kit for my jeep for the price I was going to pay for the stroker... See the problem is The engine is starting to knock and the springs are shot. I took apart a leaf pack and found out why my rear sagged so much..(The main leaf is broke).So Need help finding more sources for a engine rebuild kit for my 89 xj 4.0. I have found one so far but would like to find more to compare. As for the lift I think I am going to use the 4.5" Rusty's. Thanks, Carl

Re: Rebuild kits for the 4.0

You might try NAPA. I'm going to use one of their kits for my 4.2 in a week or so, very complete, quality parts, and for the 4.2 its a little over $400. Only thing you have to do first is pull it apart to see what you are going to need in the way of piston oversize. One advantage I have here is the motor we're doing is a spare, so no Jeep downtime excetp for the day or so for install![img]/wwwthreads_images/icons/smile.gif[/img]

Re: Rebuild kits for the 4.0

I would ask your machine shop to get the kit for you. Usually they are alot more willing to help you if you buy the parts from them. They would know exactly what to order as far as size goes, i.e. bore size, main and rod sizes. You won't know for sure until the crank is turned and the block checked or bored.

Re: Rebuild kits for the 4.0

Good advice by dorfs about the machine shop. I don't have to worry about that, my rebuild is being done at the auto shop at San Juan College. Their program won an award from the Auto Dealers Assoc. a year ago as the second best auto program in the country, so they have a pretty good shop (understatement!
