Stiffer, Slicker Shocks We’re experimenting with Sledge’s shock setup by going up on the spring rates for a slightly firmer ride and enhanced hard-packed dirt handling, but not so firm that our Sledge won’t have plenty of cushion for rough terrain. The front and rear springs are offered in two firmer rates than stock; we’re going one step up, which should keep us in the Goldilocks zone (as in, “just right”). While the shocks are off, we’ll also install the optional titanium-nitride (TiN) coated shafts for even smoother shock action and extended shaft life with a high-tech gold finish.
