Superior Axle and Gear 30 Spline Super 35 Axle Kit with Detroit Locker for 84-90 Jeep Cherokee XJ & Wrangler YJ with 3.55 and Numberically Higher Gear Ratio

If off-roading is your thing, consider upgrading to a Super 35 kit. While the original model 35 axles are adequate for street use or unmodified vehicles, aggressive trail duty or larger tires and other modifications can push these stock axles & splines beyond design limits, resulting in breakage. Super 35 kits upgrade your axles from the original 27 splines to 30 heavy-duty rolled splines, and you also get a Detroit Locker locking differential. These are up to 35% stronger than stock! Axleshafts come pre-drilled for both 5x4.5 and 5x5.5 bolt patterns.
