2013 Dodge Durango Upper Control Arm

Why Replace Your 2013 Durango Upper Control Arm

Factory upper control arm assemblies on the 2013 dodge durango front use sealed ball joints and pressed bushings that cannot be serviced. When the ball joint wears out or the bushings wear out, you replace the entire arm. That cycle repeats every 60,000-80,000 miles in normal use, faster if you tow or drive unpaved roads. JBA's upper control arm assembly eliminates that replacement loop with a rebuildable design engineered to outlast your vehicle.

The 2013 model year shares the WK2 platform with the Jeep Grand Cherokee, meaning suspension components experience identical stress points. Common problems include premature ball joint wear, torn bushings from road salt exposure, and alignment drift caused by failed upper control arm bushings. JBA's Durango upper control arms address all three failure modes with materials and serviceability that Mopar sealed assemblies cannot match.

Rebuildable Design Cuts Lifetime Repair Costs

Each arm features eight individual grease ports with pressure relief valves. You service the bushings without removing the arm from the car. Max 90 Ball Joints are CNC-machined from 4140 chromoly steel with 90-degree articulation and replaceable wear components. When a ball joint reaches the end of its life after 150,000+ miles, you unbolt it and install a new one. The arm itself carries a lifetime structural warranty and never needs replacement.

This is the same upper control arm design JBA built for jungle fleet operators running 24/7 in Central America. Those vehicles logged 200,000+ miles on a single set of arms with routine greasing and one ball joint rebuild. You get that same engineering depth whether you're running school pickup routes or weekend trail trips.

What Makes JBA Upper Control Arms Different

JBA Offroad's upper control arms use EZ Lube Bushings with eight grease ports, rather than the two horizontal bolts that pass through a standard sealed bushing. Each port feeds a specific load zone inside the bushing. Grease flows through internal channels and exits via pressure relief valves, purging contaminants and preventing over-pressurization. This system extends bushing life 3-5x compared to sealed Mopar components.

Max 90 Ball Joints are not rebranded aftermarket parts. JBA machines them in-house from 4140 chromoly steel bar stock to strict quality control standards. The 90-degree articulation range prevents binding during suspension travel. The stud, bearing race, and boot are all replaceable, which means a $60 rebuild kit restores the joint instead of a $400 arm replacement.

Gen 4.5 Refinements for 2012-2013 Models

The current Gen 4.5 design incorporates two decades of field feedback, dating back to JBA's 2003 introduction of the first aftermarket upper control arm for Jeep. Ball joint retention uses a snap ring with a machined groove, not a press fit that requires hydraulic tooling to service. Bushing shells are laser-cut from DOM tubing for dimensional consistency. Grease port fittings are stainless steel with captured O-rings to prevent thread galling during maintenance intervals.

Every arm is powder-coated in JBA Red after final assembly and inspection. The finish resists road salt, brake dust, and UV degradation better than e-coat or zinc plating. It also makes visual inspection easier during routine maintenance, so you catch wear before it becomes a safety issue.

Installation and Compatibility

JBA upper control arms bolt directly to the 2013 Dodge Durango front suspension mounts with no drilling or modification. You'll need a ball joint separator, a torque wrench, and basic hand tools. Installation takes 2-3 hours for a home mechanic with a floor jack and jack stands. The arms ship with new hardware, grease fittings installed, and detailed torque specs.

These arms fit all 2013 Durango trim levels, including police-package vehicles used by law enforcement fleets. They maintain factory ride height and work with OEM or aftermarket shocks. If you're running a leveling kit or lift, JBA arms accommodate up to 2.5 inches of front lift without geometry correction.

Maintenance Intervals

Grease the bushings every 10,000 miles or at each oil change. Each arm takes approximately 6-8 pumps of NLGI Grade 2 grease per port until you see purge from the relief valves. Inspect ball joint boots every 20,000 miles for tears or cracks. Replace boots immediately if damaged to prevent contamination of the bearing race.

Ball joints typically require rebuild or replacement at 150,000-200,000 miles, depending on use. The rebuild process takes 30 minutes per side with the arm removed from the vehicle. JBA sells rebuild kits with all wear components, or you can replace the entire ball joint assembly if the housing shows damage.

Warranty and Support

Every JBA upper control arm carries a lifetime structural warranty against defects in materials and workmanship. The warranty covers the arm body, ball joint housing, and bushing shells for as long as you own the vehicle. Wear components like ball joint bearings, boots, and bushings are considered consumables and are not covered, but their serviceability means you never replace the entire arm due to normal wear.
