This kit includes 3 components, each built and powder-coated in-house.
Enhanced Rear Suspension for Stability Comfort
Upgrade your Ram 1500 (2009–Present) with the Trail Series Fixed Rear Suspension Kit, designed to eliminate wheel hop, improve traction, and provide superior rear axle stability. Whether you're daily driving, towing, or off-roading, this kit ensures optimal suspension geometry, predictable handling, and reduced noise, vibration, and harshness (NVH) for a smoother ride.
Key Features Benefits
- Durable steel construction for maximum strength – Built with high-strength steel tubing, ensuring superior durability and longevity.
- Hybrid joint design for comfort performance – Features high-quality polyurethane bushings at one end for reduced NVH and Rock Jock Johnny Joints at the other for articulation and durability.
- Factory-length compatibility – Designed as a direct-fit upgrade for stock height, leveled, or lowered applications (up to 2” drop), maintaining proper axle positioning and suspension geometry.
- Eliminates wheel hop enhances traction – Factory rubber bushings create excessive preload on the axle, causing oscillation and instability under acceleration. This kit eliminates wheel hop by allowing controlled axle movement for better traction and launch stability.
- Optimized handling predictable steering response – Enhances suspension geometry, minimizes flex, and improves cornering precision, braking stability, and overall ride quality.
Recommended Pairing
For additional control and suspension stability, we recommend pairing this kit with our Trail Series Fixed Rear Sway Bar End Links (TRL-R-15-2009-EL2), which reduce body roll and enhance rear-end stability.
Eliminate Wheel Hop Improve Ride Quality
Wheel hop occurs when factory rubber bushings bind and oscillate under load, disrupting axle movement and reducing traction. The Trail Series Kit eliminates this issue by using a hybrid joint system—Johnny Joints for flexibility and polyurethane bushings to reduce NVH. This allows independent axle movement, ensuring smoother acceleration, better power delivery, and a more controlled ride.
Highly Durable Two-Stage Powder Coating
Each component is coated using our 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 custom look.
Optional Hardware Upgrade
This kit is designed for installation with factory hardware, but for enhanced durability and a stronger, more secure connection, we offer an optional Grade 8 hardware kit (sold separately). This upgrade provides greater reliability under heavy loads and ensures long-term performance.

All CORE 4X4 components are designed, manufactured, and tested in Orem, UT. By keeping production local, we ensure strict quality control, premium craftsmanship, and the highest standards in suspension manufacturing. Supporting American manufacturing means you get a product that’s built to last.
