Metaltech has built several for me over the past years and I broke a couple early on.. They were replaced under warranty. They learned and made design changes in a few critical areas, They now offer a heavy duty Oval tube (thats what I run) and super heavy duty square tube version for duning. Both good especially if you go longer than +2". Wide axles also put extreme twist on things...They also build Arched and Ladder-style for drag racing...
I'm gonna sell a chrome +6" , banshee style carrier housing,(no carrier). also have the banshee G-force +4" chrome axle with both sprocket and brake hub. Also have the cushion lever and HPR Revalved Resprung rear shock ,set up for 190 lb rider...whole setup minus carrier, .... I will seperate but its a great setup together.
Any interest PM me
