Extreme-Duty leaf springs are the best springs money can buy. We spared no expense when designing this product. We have carefully developed a leaf spring that you can count on to provide maximum articulation, smooth ride, increased load capacity for all the gear, durability and structural integrity to handle the extra torque from larger tires and lower gears. Some of the features include: Military wrap spring eyes, diamond cut leaves, bolt on spring clamps, antifriction sliders, top grade US steel, and the best quality control in the industry.
If your bump stops are wrong or your shackles invert i.e. your shackle stops are off you will break these. I run these on all 4 corners of a v8 powered cj7 on 37's with some mild trimming at 100 WB they flex as well as my wife's TJ and are more stable over all. I cycle a 14" shock up front and 12" inboard shocks in the rear with these and have a limiting strap on my rear diff i have found an addaleaf sometimes becomes necessary as these springs age. overall i use these in MOAB utah on all trails including prichett canyon, rubicon trail in CA, Fordyce, Barrett lake. there isn't a place i haven't been where these springs haven't been tested, they have proved very versatile. set your shackle angle between 55-60 degrees. which may require moving of the hanger. this will aid the off road performance a lot. 5" shackles eye to eye. good luck make sure to check bumpstops or you will break a spring like any leaf spring rig
I use this product for a daily driver and rock crawling. Would have rather done a coil suspension instead of waste my money.
