Now our front 5" springs are available in a heavy duty version with a 25% higher spring rate. We have added a 7th leaf and readjusted the length of the leaves to match. If you are running a larger v6 or v8 motor you will appreciate the extra weight carrying capacity of these springs. Super flexible 47" leaf springs, long travel shocks and high steer crossover steering combine to bring you up to 20 inches of articulation for serious rock crawling ability. Included with each kit is a knuckle rebuild kit, wheel bearing kits, upper axle gusset and differential armor.
