Optional Inward Bend for Larger Tires
Available as an upgrade to provide extra tire clearance, ideal for trucks running larger tires that may rub against factory control arms.
Recommended Pairing
Adjustable Front Track Bar (D-25-2003-FTB1) – For full front-end control and axle alignment, we recommend adding the Adjustable Front Track Bar, which enhances steering precision and suspension geometry.
A Complete Solution for Improved Front-End Performance
Lifting or modifying your Dodge Ram 2500 can cause caster misalignment, axle shift, and reduced steering precision. The Trail Series Adjustable Front Suspension Kit corrects these issues, ensuring proper suspension geometry, smoother handling, and long-term durability. Whether for daily driving, off-road use, or heavy hauling, this kit provides substantial improvements in stability and control.
Optional Hardware Upgrade
This set installs using factory hardware, but for increased durability and proper alignment retention, we offer an optional Grade 8 hardware kit with a cam bolt delete, available separately. This upgrade eliminates the weak factory cam bolts, ensuring better alignment stability and preventing unwanted shifting under heavy loads.
Highly Durable Two-Stage Powder Coating
Each component undergoes a two-stage powder coating process for superior durability. A zinc primer base coat provides advanced corrosion resistance, while the durable topcoat is available in 10 colors to match your build and style.
Proudly Made in the USA
All components are designed, manufactured, and tested in Orem, UT, ensuring top-tier craftsmanship and strict quality control while supporting American manufacturing.
