Universal kits work on one-ton pickups with straight-axle suspensions. An L-shaped bracket side-mounts to the frame, positioning the Aeon® rubber spring between the U-bolts.
*If the truck has a channel frame, be sure to weld extra support where the L-shaped frame bracket bolts to the frame.

Universal kits also work on medium and heavy-duty trucks.
The most popular front axle kits? HSR001 and HST001. Both kits install the same way. Because the frame bracket comes in 2 pieces, this allows the installer to adjust for alignment with the lower leaf spring.
Welding and drilling required. Timbren recommends the Aeon® rubber spring be positioned as close to the U-bolts as possible.
