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.
Confidence to Explore – Reliable, high-quality, 100% U.S.-made axle assemblies.

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.
