Re: help me understand
Not really..The Polaris style IFS (most) only use two radius arms to locate the steering knuckle. The AC uses a lower control A-arm
and a upper control A-arm that are truly A shaped. The wider base anchors to the bulk head, while the narrow end attaches to the
steering/ski knuckle. The "A" arm controls both the fore and aft relationship of the ski as well as the vertical position of the ski. On a
Polaris the radius arms control the vertical travel, the trailing arm controls the fore and aft movement (which there should be none)it
basically resists the suspension from pushing back where it doesn't belong, which is why they fail first. On an AC the "A" arms are
also fairly cheap, however, bulkhead damage can occur under large impacts. AC's damage bulkheads easier than Polaris's in my
opinion. On the flip side the AC's seem to be able to take medium impacts better without damage. I see alot of broken shocks in
AWS V AC front ends, where I rarely see it happen on Polaris's (does anyone know how to spell the plural form of Polaris ?) I don't
know why shock damage is more prevelant on the AC's....
