Description:

Kryptonite Upper Control Arms are built for serious strength, precision fitment, and long-term durability. Laser cut, machine formed, and TIG welded in small town USA, 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.

Note: When running stock wheels with oversized tires, exceeding 11.50" wide, clearance is limited and may result in rubbing on the control arm. Please contact us before purchasing if you're running this setup.

For added alignment control and long-term durability, we highly recommend the addition of Ultimate Alignment Pins, available here: https://masonbiltperformance.com/products/ultimate-alignment-pins-1999-2025-duramax?_pos=1&_sid=3760c0abb&_ss=r

**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.

All Kryptonite ball joints and rod ends come pre-greased with premium Chevron Ultra EP2 Grease and are ready to install. Service interval: every 5-7k miles. Use only a small amount of grease per joint—do not over grease.
