You're workin pretty fast. Looks great so far
Any pics of the frame mount brackets? Did you fab up all the brackets yourself? Only thing I'd look at doing is reinforcing those bushing ends where the threaded rod meets the tube. I'd add 2 angled gussets & run another wider pass around the entire rod - turn up that welder on this. I think you're okay w/ the hydro-assist w/ the sized tires you have. What drivetrain are you runnin?
