Powder Coat Process
INDUSTRIAL POWDER COATING
JBA steel upper control arms undergo a 10-stage industrial powder coating process.
Each step prepares the steel, prevents corrosion, and ensures maximum coating adhesion for long term durability.
This multi stage system protects against rust, chipping, peeling, and premature coating failure.
FINAL QUALITY INSPECTION
Every JBA upper control arm undergoes a final visual inspection to verify coating consistency, full coverage, and finish quality before leaving our facility.
WHAT POWDER COAT DO YOU USE?
The upper control arms are finished with Tiger Drylac Bengal Red powder coating and oven cured at 400°F to achieve a fully cured, durable, and long-lasting finish.

Minor chips or shop accidents can happen. We offer factory matched touch up paint. Scan the code for ordering details.
INSTALLATION
DONE RIGHT THE FIRST TIME.
Upper Control Arm Removal
Removal Procedure
1.Prior to installation, verify the part number received matches your order. Confirm Driver and Passenger side arms are correctly identified and oriented prior to removal (stamped near the ball joint).
2.Raise the vehicle and support it securely with jack stands placed under the frame rail behind the front wheel. Remove wheel. Never work under an unsupported vehicle.
3.Remove the two caliper mounting bolts and hang the caliper out of the way.
4.Remove the nut from the sway bar end link.
5.Remove the tie rod end nut. With a hammer, strike the steering knuckle to release the tie rod.
6.Remove nut from ball joint stud. Separate the ball joint from the steering knuckle. Strike the steering knuckle with a hammer to release the grip of the ball joint tapered seat in the steering knuckle.
7.Remove lower and upper mounting bolts and nuts from shock tower and remove the shock assembly.
8.Unbolt the control arm from the frame pockets and remove the upper control arm from the vehicle.

Upper Control Arm Installation
Installation Procedure
1.Apply a light coat of grease to the outer surface of the EZ Lube bushings prior to installation.
2.Position the upper control arm and install the 0.076" supplied washers closest to the shock tower. Insert the mounting bolts and apply Loctite to the threads. Torque to 122 ft-lbs (factory specs).
3.Reinstall shock assembly and torque the lower mounting bolt to 66 ft-lbs (factory spec) and torque the upper mounting nuts to 50 ft-lbs (factory spec).
4.Insert the upper ball joint stud into the steering knuckle and install the retaining nut. Use a 3/8 open end wrench on the stud to keep it from spinning. Torque the ball joint stud nut to 60 ft-lbs. Torque ball joint retaining nuts to 13 ft-lbs.
5.Connect the tie rod and torque the nut to 76ft-lbs (factory specs).
6.Reconnect the sway bar end link and torque the nut to 55ft-lbs (factory specs).
7.Reconnect the caliper and torque the bolts.

Installation Procedure Continued
8.Grease the ball joint with 3–5 pumps of lithium moly fortified EP grease until the ball joint boot just begins to swell.
9.Grease the bushings with lithium moly fortified EP grease until fresh grease is visibly pushing out from the EZ Lube ports.
10.Reinstall the wheel and torque lug nuts in a star pattern. Lower the vehicle from the jack stands.
11.Repeat the procedure on the opposite side.
12.Re-check all mounting hardware torque specifications after the first 100–300 miles.

Front End Alignment
OPTIMIZED ALIGNMENT SPECIFICATIONS
The following specifications are recommended for your specific JBA equipped vehicle:
ALIGNMENT SPECS FOR JBA 19.0
ALIGNMENT TERMS & LIFT EFFECTS
Camber is the inward or outward tilt of the tire when viewed from the front of the vehicle. Too much negative or positive camber can cause uneven tire wear.
Caster is the forward or rearward tilt of the steering axis when viewed from the side. More positive caster improves straight-line stability and steering wheel return to center.
Toe is the direction the tires point relative to each other when viewed from above. Incorrect toe is the fastest way to destroy tires.
Lifting an independent front suspension reduces positive caster, which can cause light steering and reduced highway stability. JBA upper control arms restore lost caster to improve tracking, steering return, and overall stability.
Maintenance Procedure
BALL JOINTS
Pump grease into the ball joint zerk fitting until the rubber boot just starts to swell, at least 3-4 pumps.
EZ-LUBE BUSHINGS
Pump grease into the bushing zerk fitting until fresh grease exits the EZ-Lube ports.
SERVICE INTERVAL
Pump fresh grease into the ball joints and EzLube Bushings every 3000-5000 miles or after deep mud, water crossings, or heavy off road use.
WHAT GREASE SHOULD I USE?
Use only lithium moly fortified EP grease. Using the wrong grease can lead to premature wear and failure.
APPROVED GREASE EXAMPLES:
Mobilgrease XHP 222 Special Grease
Chevron EP Moly
Valvoline Multi Vehicle Moly Fortified
REPEATEVERY3-5K MILES

ABOUT US WHY JBA EXISTS.
Our Story
WHERE IT BEGAN
JBA started in 2004 when Al Handy lifted his Jeep Liberty and the factory upper control arms failed prematurely. As an engineer, he refused to accept that compromise was normal. He designed a better upper control arm, modeled after oval track race car geometry, and installed the first generation on his own vehicle. One solution become a mission.
HOW IT GREW
Through multiple generations of refinement and expanded platforms, that original design evolved. In 2007, Marlin Gehman’s ownership carried the vision forward, improving serviceability, introducing bolt-in ball joints, and ultimately focusing exclusively on building the best upper control arms possible. Growth didn’t mean chasing everything. It meant sharpening our focus.
BUILT WITH CONVICTION
We are a family-run company, and we strive to treat people the way we would want our own family treated. That applies to our customers, our team, and our partners.
