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.
FINALQUALITYINSPECTION
Every JBA upper control arm undergoes a final visual inspection to verify coating consistency, full coverage, and finish quality before leaving our facility.
WHATPOWDERCOATDOYOUUSE?
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.

Upper Control Arm Removal
Removal Procedure
1.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 nut from the ball joint stud.
4.Separate the ball joint from the steering knuckle. Strike the steering knuckle with a hammer to release the ball joint.
5.Remove the nut on each bushing, pull out the bolts, and remove the upper control arm.
Driver Side Only:
Remove plastic fastener located on the splash guard. Behind the bracket, loosen the bolt that secures the upper steering shaft and universal joint.
Use a pen to mark the steering shaft and universal joint so that they line back up when reassembled. Once the bolt is removed, push the steering shaft towards the firewall, giving you room for step 5.
Upper Control Arm Installation
Installation Procedure
1.Remove the factory washer on the sheer bolt. To remove the factory washer, use a large socket that fits over the flange bolt head without contacting the bolt itself. Place the socket against the washer and strike the socket until the washer is freed from the bolt. Install the JBA supplied washer before proceding.
2.Lubricate the bushing surfaces before installation with lithuim moly fortified EP grease.
3.Hold the UCA in place and insert the long sheer bolt. Add Loctite (thread-locker) before tightening the bolt. Keep the factory washer connected to the nut. Torque the bolt to 90 ft-lbs.
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.
Driver Side Only:
Pull the steering shaft toward the universal joint and reconnect where the markings from the removal line up. Behind the bracket, loosen the bolt that secures the upper steering shaft and universal joint. Install the bolt, and the plastic fastener in the splash guard.

Upper Control Arm Installation
Installation Procedure Continued
5.Grease the ball joint with 3–5 pumps of lithium moly fortified EP grease until the ball joint boot just begins to swell.
6.Grease the bushings with lithium moly fortified EP grease until fresh grease is visibly pushing out from the EZ Lube ports.
7.Reinstall the wheel and torque lug nuts in a star pattern. Lower the vehicle from the jack stands.
8.Repeat the procedure on the opposite side.
9.Re-check all mounting hardware torque specifications after the first 100–300 miles. Forgreasespecifications,seeMaintenanceProcedure(page15)orvisitourFAQ.

Front End Alignment
OPTIMIZEDALIGNMENTSPECIFICATIONS
The following specifications are recommended for your specific JBA equipped vehicle:
ALIGNMENTTERMS&LIFTEFFECTS
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.
