looking for double adjustable rear shocks

[pfordamx]

they don't offer the radial slick in a 28x10.5 they might in a 28x9 which would be something to consider we run a NA stock block local heads up deal that limits us to a 28x10.5 and radials are said to be a little quicker than a bias ply slick. we have suspension limiters on the front that hit way before the shocks we could probably add another 1.5-2.0 inchs of travel if needed we also can't run wheelie bars so we don't really want bumper dragging wheel stands.i figured our issues were more in the back of the car hence why i was asking about shocks. also thinking of adding an anti roll bar the car seems to want to twist more than i'm happy with.
