    I have a 99 tj, with a 2.5-3" lift in it, they replaced the coils, with longer ones. It had 2200# front rating, do you think the lift springs would increase the rating somewhat? Rides like a lumberwagon. 99 tj, 4,0, 5 sp.

    Let me guess, you got Skyjacker springs?

    The axle rating is based on all kinds of things

    size; of brakes, of ball joints, tie-rod ends, wheel bearings, axle tube wall thickness and diameter. U-joint size.... the list goes on and on.

    just changing the springs while keeping the jeep level and riding like a truck. does not necessarily change the axle rating.

    What do you want to do? You have the same wheel bearings as a D44 and the same U-joint as some 1 ton trucks.

    I get 75 to 100K out of wheel bearings and tie-rods, ball joints last over 120k Thats with a 700# plow

    your brakes are not up to par for stopping a 700# plow from 75 MPH without over heating.

    not sure on the springs, I know the door jamb says 2200#, but has the 4.0 in. I believe I have the heavier axles, I'll go and take a pic of the axles and post on here. I may want to put a plow on for next year, no blizzard 810, but more like a sd 68, snowdog.

    I was just wondering if these were a little stiffer then the stock ones, this is the first wrangler type jeep I have ridden in, so I don't know what a stock tj rides like. Whats the back one, it has the screw in plug, a 35?? Are the d30's pretty good axles? Thanks

    If it has a screw plug it's a d44, here is a link

    The d30's and d44 fronts have the same ball joints, axle tubes and outer knuckles. The d44's have stronger ring and pinion gears.
