Pricing for materials and casting has tripled. We are trying to get something worked out but for now this product is unavailable.

AS SEEN ON EXTREME 4X4! These new arms are standard length. The adjustable caster radius arm, head, and cap are stronger than the stock radius arms. The arms are modular so parts can be changed out or replaced. They can be adjusted to 15 degrees of caster. The side plates (1/4″ thick) hold the adjustable head to the 2″x2″x1/4″ arms and are used to mount 1 or 2 shocks. The rear of the arm is slotted for the 1″ heim joint. The shoulder nuts allow the heim to mount to the stock radius arm frame mounts. The Heim joint (rod end) is top of the line stuff. This Teflon lined rod end has a 1″ shank and 14 threads per inch, a 1″ hole in the center and a ULT. static radial load of 43,555 lbs. This thing is so beefy it weighs over 2 lbs! All bolts are grade 8. The listed price is for 2 complete radius arms with caps, stock length 2″x2″ arm, brake line brackets, and caster checker tool. (For Heim info on FK161JMT go to
