Yes i have done some checking myself and have found that Houser by there specs are making the longist arm at 2 1/2 with the longist shock at 19 1/2 but you will have to run a 1-4 inset wheel to keep it under 50 inch with TBR's set up of +3 it will make you wider that 50" they said they made that setup for the desert racers but i have a set of brand new Burguard's on here for sell with long travel elkas that will be here the begging of next week
I think the walsh are 2 1/2. I got my WALSH from www.tandtracing.com They also had a few of Pro Trax front ends in stock too, but I'm not sure if they are 2 1/2 or +3. I also run the 4+1 wheels. I like the WALSH and Laeger. The pro trax is expensive for my blood, but the new long shock laeger arms are neat.
