Important Fitment Details:
Note: When running stock wheels with oversized tires, exceeding 11.50" wide, clearance is limited and may result in rubbing on the control arm.
Features:
- Maximizes Adjustability - These arms optimize suspension geometry, restoring down travel when height is increased via torsion key adjustments.
- Robust Boxed Design - 3/16" plate steel hand and machine welded into an extremely strong UCA.
- Alignment Made Easy - Based on your trucks alignment needs our ball joint can be mounted either on top of or underneath the ball joint pocket making your alignment adjustment super easy to make without inducing extreme angles.
-
Greaseable By Design – Apply 4–6 pumps during installation, then maintain with approximately 2-4 pumps every 5,000–7,000 miles. Designed to purge contaminants without overfilling the boot.
Description:
Kryptonite Upper Control Arms are built for serious strength, precision fitment, and long-term durability. Laser cut, machine formed, and precision welded, these control arms are engineered to improve ride quality on any leveled, lifted, or even stock-height GM 2500–3500 HD truck. Compatible with most aftermarket suspension systems, these arms are a true upgrade over factory components.
**GREASE PORT LOCATION IMPROVEMENTS:
Accessing UCA grease fittings is now easier with updated port locations. Kits include multiple grease fittings and port plugs for maximum serviceability regardless of arm position.
Ball joint Service interval: 3 pumps of grease upon installation then every 5-7k miles. Use only a small amount of grease per joint—do not over grease.
