Yes. However, the new radius arm location will be where the transmission cross-member is located.
Here is the procedure you will need to do (or eaaaasily pay someone to do.
There are 3 rivets on your outside frame rail where your transmission cross-member is attached. That is where your radius arm brackets will need to be placed to retain original geometry.
1) Remove x-member by drilling or grinding off the rivets. Take not of locations and measurements in relation to the front axle.
2) Get 2"x4" box steel, cut it, and run it on your frame rails, inside the C-channel. Drill 2 holes per side, using grade 8 hardware to secure the new member to the frame. It provides transmission support and frame rigidity.
3) Weld the stock radius arm brackets to the outside of the frame.
4) If you want to add optional 2" spring lift or more, now is the time to do it.
It sounds simple, but is still a tedious task. If you can't weld, take it to a friend who can or a shop.
The extended radius arms are way superior to stock drop brackets and stock arms.
This is NOT flex. lol This is WITHOUT the extended radius arms, and just the stock arms and Trailmaster drop brackets for the RA.
At this point, I'm not pushing to make a sale. I'm informing you what is required if you want to run simply the longer arms. Also, I'm showing you that my TTB doesn't flex well, but I sitll wheel it anyways. The picture has 3" RA drop brackets, SJ 6" springs, and stock length RA.
