Ya, you prolly haven't seen too many axles like mine
I'm the only one building them that I know of
I build the axles in-house...
The axles start out as 7 seperate peices,Tool steel liner, An inner sleeve, Drive flange(that's the part that drives the hubs), then an outer sleeve that the sprocket carrier is welded to, then the retaining nuts for the hubs... The axles are fairly strong, not indestuctable I have managed to break and bend afew...But I drive the buggies like I stole them, The Hubs on the other hand are pretty much Indesrtructable...1/4'' Boilerplate, Mumbler trues the 1/4'' collar so it's 90* on both ends, CNCs the mating surface so it's all nice flat, true, and punch the bolt pattern, before I weld them up...Since most of my stuff turns left(roudy round) I put 4 gussets on the right drive hub and only 3 on the left,,,Then I have Mumbler Turn them in the lathe to check bolt holes and run-out for the wheel mounting surface...
I don't harden them so they can flex...We have hardened them in the past, but then you get little or no warning when the axle is going to break...Plus if you get a small tweek in it ...It can be heated and straightened
Dual shocks can be a pain in the ass...
I like dual shocks fo several reasons
1) I can tailor spring rates for ride height,sag and compression(not really compression but ride feel)
2) I have tons of coil over shocks and springs laying around
3) I can mout dual coil overs inboard and cantaleverd and go way over the ''acceptable ratio'' of shock placement, and not have ungodly pressure on the individual shock
4) with a little thought and some foresite you can get some big travel numbers out of an inexpensive shock
5) They look cool
,,,,And they run cooler than 1 shock doing all the work, because they only move a fraction of what a long travel outboard shock does...So less shock fade
You could take this one off my hands
