Lift Kits, Gearing Changes, and Off-Road Fabrication in Nampa

If you need 4x4 fabrication in Nampa, you're likely planning a lift kit install, a gear ratio change, or an axle swap to improve off-road capability or accommodate larger tires. Les Bois Automotive handles four-wheel-drive modifications that range from bolt-on suspension lifts to custom-fabricated long-travel setups. Whether you're building a truck for weekend trail runs or upgrading your daily driver to handle deeper snow and rougher roads, the shop works with you to design a system that balances ground clearance, articulation, and on-road drivability.

Nampa's proximity to diverse terrain—from high desert trails to forested mountain routes—means your 4x4 needs to handle varied obstacles without sacrificing reliability. A lift kit increases ground clearance and allows for larger, more aggressive tires, but it also changes your vehicle's center of gravity and drivetrain angles. The shop addresses these factors by installing extended brake lines, adjustable track bars, and corrected driveshafts to maintain safe steering geometry and prevent vibration. Gearing changes compensate for the added rotational mass of oversized tires, restoring acceleration and improving fuel economy.

When you move to 35-inch tires or larger, your factory axles and ring-and-pinion gears may struggle to deliver adequate torque. Swapping to a stronger axle assembly with a lower gear ratio ensures your engine stays in its power band, whether you're climbing a steep grade or crawling over rocks. The shop sources and installs axles that match your vehicle's bolt pattern and suspension width, then sets up the differential with the correct pinion depth, backlash, and bearing preload to prevent noise and premature wear.

Lift kit installation varies depending on your vehicle and intended use. Coil spring lifts provide a smoother ride and better articulation, while leaf spring lifts are simpler and more durable for heavy loads. Extensions and spacer lifts offer budget-friendly height gains but may limit suspension travel. The shop evaluates your goals and recommends components that deliver the clearance and performance you need without introducing steering wander or excessive body roll on pavement.

Building a capable 4x4 involves more than adding height and bigger tires. It requires balancing suspension geometry, drivetrain strength, braking performance, and steering response.

Whether you're upgrading for daily winter driving or preparing for multi-day backcountry trips, each modification is chosen to improve capability without compromising safety or reliability.
