Henslee Motorsports designed the rear 4-link suspension. 29 inches of wheel travel are achieved using 2.5 Sway-A-Way coilovers and Fox 3.0 bypass shocks. There is also a set of Fox 2.0 airbumps in the rear. So that makes Fox, King and Sway-A-Way all on the same truck. I wonder if his next build will add Bilstein, Radflo, and FOA? The billet aluminum sway bar is also a product of Henslee.
