Dynatrac JK Serious Performance 44/60 Axle Set - 5.38, ARB

Upgrade your 2007-2018 Jeep Wrangler JK with the Dynatrac JK Serious Performance 44/60 Axle Set — the ultimate answer for the weekend warrior who wants major strength gains without breaking the bank. You get an assembled ProRock 44 front and ProRock 60 semi-float rear, both retaining your factory bolt pattern and brakes so you can run 33- to 37-inch tires without buying new wheels.

Why Choose the Dynatrac ProRock 44/60 Axle Set?

• Keeps Your Wheels & Brakes – Retains factory bolt pattern and brakes, saving you $1,500 to $2,500 over an axle upgrade that forces new wheels.
• Built for 33"–37" Tires – Unquestionable strength and reliability across the most common JK tire sizes.
• ProRock 44 Front – Patented nodular-iron high-pinion centersection with best-in-class ground clearance — more than a factory Dana 30 — and control arm bushings installed.
• 3x Stronger Front Housing – 3" diameter x ½" wall tubing, three times stronger than any stock JK Dana 44 housing.
• ProRock 60 Rear – Patented nodular-iron high-pinion centersection with more ground clearance than a factory Dana 44 and a 2.75" raised driveshaft height to protect the driveshaft and U-joint from rock strikes.
• 2.5x Stronger Rear Housing – 3.125" diameter x 0.313" wall tubing, 2.5 times stronger than any stock JK Dana 44 rear housing.
• Forged U.S.-Made Shafts – Double-heat-treated 1350 4340 inner and outer front shafts with new U-joints, plus forged heat-treated 35-spline alloy-steel rear shafts.
• HD BallJoints Installed – Dynatrac HD BallJoints — the last balljoints you'll ever need.

Fits These Models

Fits the 2007-2017 Jeep Wrangler (4WD) and the 2018 Jeep Wrangler JK (4WD). This is a JK-generation axle set — the 2018 fitment covers the JK holdover model, not the JL.

Notes

• Does NOT include knuckles or brakes.
• Axles shown in product photos feature the optional Dynatrac Big Brake Kit (DT JK44-2X1125-A), sold separately.
• Using the integrated ram-assist bracket on the ProRock 44 requires flipping the drag link.
• The ram-assist/steering stabilizer bracket for the ProRock 44 is not compatible with Reid Racing knuckles. If you're running Reid Racing knuckles, Dynatrac can substitute their first-generation raised track-bar bracket (no integrated ram-assist/steering stabilizer mount).
• CA Residents: Prop 65 Warning applies.
