We ran the Duff stage 1 kit for years. That the stock RA with the Duff drop brackets and Duff springs. By years I mean we actually wore out a set of springs (> 150k miles).

I really like the progressive rate of the duff springs. That, in combination with rs9000's and f-250 shock mounts (longer shocks) made the front end ride really well.

We than ran Extended RA arms (not duffs) and the ride wasn't better BUT the extra suspension travel was really nice.

At this current point the only part of the duff kit we still use is their 3.5" lift springs. I really like the ride of them and I'm having a hard time finding what to replace them with (3.5" springs with f-150 spacers for 5" of lift)..

..Looking at your signature it appears you already know Brandon and Travis (BTF Fab a vendor here)..

..Why not have them build you a set of radius arms? They can build it for any size ttb lift, width, and will include the proper caster..

..I am really surprised at the price quoted from BTF..:scratch:..I really don't think they are nearly that much from them..I had them build me two different sets for two different style trucks and I think they were cheaper..:scratch:..it has been a couple years though and all the material has gone way up..

..Maniak as well as others have built/modified/extended stock RA's for a somewhat inexpensive answer to RA's..

..You could make "pockets" for the RA's to mount to in front of the existing cross member or, you can extend the RA's so the pockets land at the stock tranny cross member location, then build your own tranny crossmember that attaches to these pockets..
