I've ordered springs from different retailers in the past and none of the other brands come close to the Heavy Duty Quality as these. For the price paid, these springs are well built and much thicker than the same weight class as the competitors. Plan on buying all my future axle spring kits from this retailer. **I will be adding pics in the next 24 hrs. with a side-by-side comparison to a same price bracket competitor.**

A quality kit with everything needed to mount your 3500 pound axle. Spring mounts, shackles and u bolt plates are galvanized. Bushings are pressed into the springs and there is a durable coat of paint on them.
