Still don't understand the idea behind putting these on crawler.Don't you think a crawler that has the right spring setup on the coil overs and the right valving would do fine without binding the suspension? Drag cars run the same things and call them anti rolls, the idea is to put equal pressure on both rear tires to make the car go straight when the front end is in the air, aka no flex. Could possible see them on the front end for wide open hill shots, but would love to see alot of the bigger rigs undo the rear anti rock to see if they could benefit from the flex making the rigs crawl things instead of having to hit **** wide open, although it wouldn't be near as entertaining.
