This kit includes 3 components, each built and powder-coated in-house.
Enhanced Stability Suspension Control
Maximize the control and performance of your Ram 1500 (2009–Present) with the Trail Series Adjustable Rear Suspension Kit. Designed for city driving, towing, and off-road performance, this complete kit provides adjustability to fine-tune rear axle alignment, eliminate wheel hop, reduce driveline vibrations, and improve overall ride quality.
Key Features Benefits
- High-strength DOM tubing construction – Built with heavy-wall DOM tubing, offering a balance of strength and durability to withstand extreme conditions.
- Rock Jock Johnny Joints high-grade polyurethane bushings – Features Johnny Joints at the adjustable ends for maximum articulation and polyurethane bushings on the fixed ends to minimize NVH (noise, vibration, and harshness).
- Easily adjustable for rear axle pinion angle alignment – Allows for precise adjustments to correct driveline angle and optimize suspension geometry.
- Eliminates wheel hop enhances traction – Factory rubber bushings preload the axle, causing instability under acceleration. Our Trail Series kit reduces axle movement, improving traction and ensuring smooth power delivery.
Recommended Pairing for Total Suspension Control
For optimal rear-end stability, we recommend pairing this kit with Trail Series Adjustable Rear Sway Bar End Links (TRL-R-15-2009-EL2) to further improve stability and cornering performance.
Fine-Tune Rear Axle Alignment Pinion Angle
Unlike factory control arms, which lack adjustability, the Trail Series Adjustable Rear Suspension Kit gives you full control over pinion angle and axle positioning, reducing driveline vibrations, improving traction, and maintaining proper geometry—essential for lifted or modified trucks.
Highly Durable Two-Stage Powder Coating
Each component undergoes a two-stage powder coating process for long-term durability. The first stage includes a zinc primer base coat for maximum rust resistance, followed by a durable topcoat available in 10 color options for a customized look.
Optional Hardware Upgrade
Designed for installation using factory hardware, but for enhanced durability and a more secure installation, we offer an optional Grade 8 hardware kit (sold separately).
Proudly Made in the USA
Manufactured in Orem, UT, every CORE 4X4 component meets strict quality control standards for precision, strength, and long-term durability.
