We now have two versions of our extensions. One with a heim joint and the other has a
grade 8 stud. The stud version allows you to reuse your stock frame mount after it is moved
back. The stud is the same length as the stud on the end of the stock radius arm. These
extensions thread onto the existing threads of your radius arm to ensure every thing is
straight before welding. The extensions add about 10-1/2" to the over all length of the radius
arm. They can also be viewed in Bronco Driver issue 13 page 64. The cost of the extensions
are $135 dollars plus shipping for the pair.

Steering Box Girdle
Large tires and locked axles apply a tremendous amount of force to our frames and steering
boxes. Many of us have experienced our frames cracking and the steering boxes moving
under heavy loads. Stone Crusher’s steering box girdle made from 1/4” plate not only
reinforces the frame but also supports the steering box to help prevent these problems. It
mounts to the inside of the frame using the stock steering box bolts. Four supplied bolts go
through the girdle and into the top of the steering box.
$90.00 plus shipping
To go along our heim joint style extensions, we are now offering frame mounting
brackets. Made from 1/4" material, the brackets sandwiches the frame. Insuring a
good solid mount, they come up 3 inches on each side. The brackets come as a set
for $45 plus shipping.
