Complete Front-End Solution for Maximum Performance
Upgrade your Dodge Ram 4500 (2008-2020) with our Adjustable Front Control Arm Set, designed to eliminate alignment issues, optimize suspension geometry, and enhance handling for heavy-duty applications. Whether you're towing, hauling, or off-roading, this complete front-end solution allows precise axle positioning, including pushing the front axle forward (“the stretch”) to fit larger tires without interference at the fender liner.
Key Features Benefits
- Heavy-Duty DOM Tubing Construction – Built from 1.75" OD DOM steel tubing with .313" wall thickness, these control arms provide exceptional strength for heavy towing, hauling, and extreme off-road conditions.
- Rock Jock Johnny Joints for Maximum Durability – Equipped with fully greaseable and rebuildable Rock Jock Johnny Joints, ensuring superior flexibility and long-lasting performance under extreme loads.
- On-Vehicle Adjustability for Precision Alignment – Left-hand and right-hand threaded adjusters allow for fine-tuning caster and pinion angles without removal, ensuring perfect alignment correction for 0 to 6 inches of lift.
- Optimized for Larger Tires Improved Steering Stability – Designed to push the front axle forward (“the stretch”), creating extra clearance for larger tires while maintaining proper caster angles for improved handling.
Recommended Pairing
Adjustable Front Track Bar (D-45-2008-FTB1) – For full front-end stability and steering precision, pair this set with the Adjustable Front Track Bar to eliminate bump steer and enhance steering control.
Optimized Suspension Performance
Our Adjustable Front Control Arm Set is a critical upgrade for restoring caster alignment, reducing wandering at highway speeds, and improving steering stability. Paired together, upper and lower control arms provide full axle recentering, reducing suspension stress and premature tire wear. For trucks used in towing and hauling, correcting caster angles is essential for maintaining stability and control under heavy loads.
Two-Stage Powder Coating
To ensure maximum durability and corrosion resistance, all control arms undergo a two-stage powder coating process. The first stage includes a zinc primer base coat, offering superior rust prevention and long-term protection. The second stage applies a durable top coat, available in 10 color options, allowing you to customize your suspension components while ensuring a long-lasting, high-quality finish.
Made in the USA
Proudly manufactured in Orem, UT, our control arms are built with American-sourced materials, ensuring strict quality control and superior reliability. Supporting American manufacturing means investing in premium craftsmanship and long-lasting performance for both work and off-road applications.
Optional Hardware Upgrade
These control arms install using factory hardware, but for rusted or stubborn bolts, we offer Grade 8 hardware kits, available separately, for a hassle-free installation.
