these 6" lift leaf springs replaced my 6" lift blocks. I have to say its a major differnece for my 96 Bronco Build. I load the rig down with alot of water rescue equipment. 5 leaves plus an Overload leaf is a beast...
Excellent customer service and support! Speedy delivery
Great springs. Good ride quality. Nice finish, Pro Comp makes quality products.
The springs ride great. The bolts required are 9/16, bothe ends. I used these to lift a 2nd gen Ford Explorer. I converted them to spring under axle. I was happy to see these are equipped with a pinion wedge.
They fit perfectly on my 1983 c30 crew cab. I solid axle swapped the truck and these made to easy to do the rear suspension
Nice springs paints a lil messed up but who gives a shight its goin on a truck its not a show truck so i could careless but overall bery good spring n company shipped super fast
Great ride for the price, I didn’t expect the ride to be so plush compared to the stuff stock springs. I wanted Deavers but those are cost prohibitive and I already spent my budget on fox resi shocks, I was Pleasantly surprised with these, I don’t use my truck to haul so if I lost some payload capacity I don’t really care too much.
Springs greatly improved ride quality and worked well. More of a 4” lift than a 6 in my truck tho.

Q: I have a 2004 F250 6.0, it's a 4x4 with rear factory blocks. Will it only lift the truck 2 inches if I take out the factory block, then install the new springs? Answer this question
A: Depends on the height of the rear block Ford had 2.5 inch rear blocks and 2 inch I believe in those years.

A: That’s what I did to my 2006 F250, installed these springs and removed the blocks. Trucks rides so much better. The factory springs are too stiff and made for hauling

Q: I have the Rough Country 1.5" lift on right now and my tail end is sagging a lot. I was thinking of getting another lift that came with new leaf springs but thought I might try this first. Would these spings work with the 1.5" lift? Answer this question
A: Assuming your lift kit is the one with a coil spring spacer up front, and a shackle lift in the back, then yes. If you combine your shackle 1.5” lift and these 3.5” leaf springs they will give you a total of 5” lift. Unless you put your stock oem shackle back on and go only 3.5”. You will need new shocks most likely, and a t case drop or SYE, and watch out for your brake lines as well. May need new longer ones. You can use OEM jeep YJ brake lines, they are longer than the stock XJ lines

Q: What’s the load rate of a pair of 13511 leaf springs? Also is there a drawing showing measurements? Answer this question
A: Hey "Brent", why didn't you just answer the man's question. I have the same questions. You can't tell jack from the blurry schematic and it says nothing of load capacity. Your answer is sarcastic and uninformative. Info please??

Q: what country are they made in Answer this question
A: I was looking for the marking, once I uncovered the silt mud and dirt from the past 2 Baja 1000’s I noticed they said made in ….. for the price I doubt they are made stateside, they ride very smooth and forgiving, better highway ride that the stock springs, as long as you have some good , not rancho or procomp, shocks. You lose some towing capability but only thing I tow is a small keg of Double Barrel Ale. See you on the other side!
