The "BTF Heavy Duty Spring Perch for Dana 44/10 Bolt/Ford 9" is the ultimate in anti-wrap spring perches. These perchs are unique in that the spring mounting surface is 2 1/2" wide so the whole spring will rest on the perch. Other perches that are bent on a bress brake only support the middle part of the spring. It is fabricated from 5/16" high-strength steel plate. These perches were designed to fit axle tubes from 3 1/16" to 3 1/2" in diameter. The spring mounting pad measures 2 1/2" x 7". The distance from the top of the axle tube to the spring mounting surface is 1". This perch has one center pin hole in the middle to leave your options open for offseting the center pin. Sold in pairs (enough for one axle).
Notice that the whole width of the leaf spring is supported by our spring perches, not only 60% of it like some others. We have been building spring perches like this for years. Check out our other spring perches for rear alxe applications.
