Why are these arms so different?
Their are 5 major differences between our new arms and stock
and about that many differences between our arms and others available in the
Our new stock length radius arms allow you to bolt in a new
radius arm without cutting or modifying your frame.
These new radius arms are a completely new unit we do not
modify old used stock arms or reuse the front cap.
You can replace any and all parts of our new arms in the
event of failure or if you want to customize
You can adjust the caster from 0* to 15* without all of the
work of replacing C bushings.
We added in a place to add an extra shock or limit strap
behind the axle out of the way of the steering linkage.
#1 The radius arm head and cap are cast out of Chromoly, much
stronger than stock.
#2 This new arm is a unique design, the Chromoly head is cast so that you
can adjust the caster up to 15* without changing C bushings.
#3 The main part of the arm is made of 2" X 2" X 1/4" wall
square tubing with a milled notch for the rod end. You can order this part
stock or 11" longer but you can customize it from there, if you want it only
5" longer, just cut the end nearest the head and drill 2 new holes.
#4 The ability to mount two shocks on the back side of the head
or one shock and a limit strap.
#5 This rod end JM16-1T is HUGE featuring a
Teflon liner a 1" shank and a static radial load of 43,555 Lbs this thing is
so massive it weights 4 Lbs.
#6 These Chromoly radius arm bushings allow you to retain
your stock bracket and run a rod end when using our stock length radius arms
If you are going to use our extended arm you will have to cut the stock
bracket off of the frame and weld on the new bracket that comes with the
long arm kit.

The radius arms are cast as two parts then the parts are machined and the holes are taped.
