Going to swap 1 ton 14FF onto a Burb. Which spring perch do you guys think may be a better choice? I'm kind of leaning towards this one because it is 8" long and I think it may contribute to less axle hop (as also stated on the website) and more options on moving the axle 1" forward or back to adjust wheelbase (in case I do a shackle flip): http://www.ruffstuffspecialties.com/catalog/differential-spring-p-63.html at $28. The DIY one looks ok too, but I like the longer design of the above. http://www.diy4x.com/suspension.htm halfway down page pn#00087 at $40. It also allows for axle positioning changes. Looks to be about 5" long? My use it DD/highway and trail. Not an uber flexy matchine.
