    I haven't found a link yet to some stock ones . But the stock replacements I found at JC whitney are :

    Leaf Spring - Front, with 2 Leaves 1850 lbs. Capacity
    Leaf Spring - Front, with heavy duty leaves 2250 lbs. capacity
    (approx. 52" long) Leaf Spring - Rear, with 6 Leaves, 1875 lbs. Capacity
    Leaf Spring - Rear, with 7 Leaves, 2850 lbs. Capacity
    4WD (approx. 52" Long) Leaf Spring - Rear, with 7 Leaves, 2850 lbs. Capacity


    I have no idea on how close to stock these are . I am looking for a list of stock rates today in my slower times /forums/images/graemlins/thumb.gif

    Thanks for the info. I am most intrested in how the stock springs fit into the window of replacement lift springs. I would like something close to the stock rate, maybe a bit higher. Anyone have some input?

    Well looking at prices , stock replacements , and lift springs , cost about the same when purchased as springs only .

    And looking at ride quality and load capacity . The supposedly stiff ( people must want Caddillac's LOL ) Pro Comp and Rough Country springs , ride just like the stock springs ( which I like ) /forums/images/graemlins/k5.gif /forums/images/graemlins/k5.gif

    2in lift but DO NOT want soft or bouncy springs, truck is 90% daily driver.

    You are going to get a little bounce , even stock , I think it is our wheelbase , like when you hit a bump and it rocks front to rear just a bit . If you want to go 2 inches , any companies springs will be fine . You will like the ride if you are already happy with your current truck /forums/images/graemlins/k5.gif /forums/images/graemlins/k5.gif

    I know you said 2" lift, but I posted a p/n a while back for a Rancho 4" spring that has something like 9 leaves. They ride really nice in my SBC powered Sub. You could always take out a couple leaves to get the lower ride height you want. Start with the shorter leaves.
