I have a 1990 Cherokee Laredo, It has 250,000 miles with the original timing chain. We are thinking about changing it out due to miles and we will be replacing rear main seal since it leaks figure do it at same time. My question is: Since it is hard to get Mopar parts, what brand is best to buy.

 

comp cams timing chain set. Might as well replace the gears while you're at it.
