Why Builders Choose CORE 4X4
Warranty facts, not marketing language.
Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.
Skip a maintenance interval? Their warranty voids. Ours doesn’t.
Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

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.

This upgrade eliminates the weak factory cam bolts, ensuring better alignment stability and preventing unwanted shifting under heavy loads.

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.
