Alldogs Offroad coil springs are manufatured in the USA with American steel. We did extensive research and scouted producers across the country to find the best coil spring manufaturer out there. The manufacturer we've partnered with is a significant producer of coil springs for the military. Their coil springs are also found in nuclear reactors across the country. We're confident there isn't a better manufacturer out there. These are the springs your rig deserves to have.
We use hot 5160H alloy American steel rolled over a precision mandrel to produce coils with exacting tolerances. These coils are oil quenched, run through a temper furnace, shot peened, inspected, powder coated, and printed with the Alldogs logo and partnumber. Each batch is tested to maintain uniform spring rates.
These springs are manufactured to give roughly 2" of lift, depending on the weight of the vehicle.
