Is it ok to use sulastic shackles with caltrax traction sys for drags and or pulling 3500 ccdrw and i still have helpers, 550 rwhp allison.
Well I was wrong ,according to the tec guy I just spoke to at Calvert Racing they do not sell bars that connect to the holes in the front plate on Caltracs system like I thought I heard .
Those shackles won't change much. If you are that worried about it set the cal tracs up like they recommend and get your fattest buddy to jump up and down in the bed and see what it does to your caltracs preload.
I like things a little more cushy .LOL
I had sulastic shackles on my truck. The only thing I noticed was it squatted more with a load. I put stock shackles back on and didn't notice much change in the ride if any.
