Custom Builds

What does the 4-wheel drive vehicle of your dreams include? What does it take to have a real rock crawler ready for off road challenges? We can modify your vehicle for better 4×4 performance. Bring in your Jeep, Truck, or Buggies and design the vehicle of your dreams. Call for a personal design and fabrication planning meeting.

Boise 4×4 is equipped to tackle any project.

Want to take your ride off road? You will want to consider upgrading and modifying the following:

Shocks- Stock shocks are not designed for rock crawling, rough uneven surfaces or increased wheel/tire size. You will also want to consider the amount of wear on shocks. Over time heat develops a foamy oil that decreases your shock’s damping strength which is important for a smooth ride.

Exhaust System- Off-roading requires an exhaust with an increased airflow since your engine will need to reduce back pressure and turbulence. With a stock exhaust noise control is the main purpose. An upgrade will increase efficiency while giving you the pleasing sound of a rock crawler. Gear changes are necessary when running larger tires. A balance between more power and better fuel economy needs to be found to meet intended vehicle use requirements.

Tires and Wheels- Replacing stock tires on off-road vehicles with tires that have increased width, tread, and height will increase your four-wheel drive performance. Depending on the type of conditions you plan to use your vehicle in you will want to have a tire specialized for mud, sand, snow, rock crawling or an all-terrain tire depending on it’s specific use.

Gearing-Gear changes are necessary when running larger tires. A balance between more power and better fuel economy needs to be found to meet intended vehicle use requirements.

Intake System- Off-roading creates a dirty engine environment that can potentially be detrimental to your engine. Upgrades will provide the clean air necessary for combustion and longer engine life.

Suspension- Ground clearance and articulation is vital to rock crawling and off-roading. Damage to undercarriage can occur with stock suspension. Modifying your suspension will permit you to have larger tires, more ground clearance, and more fun.

Traction- Locking differentials give a rig a “lock” on both wheels on an axle forcing the wheels to turn together which increases the traction available to either wheel individually. This decreases the chance of getting stuck.

Digital System- Newer 4×4 vehicles come with an ECU (engine control unit) programmed with factory settings. Modifying this system can generate more power from your engine.

Brakes- Running larger tires, crawling over rocks or racing through dirt, sand, and mud increase the stress on your braking system. When you make modifications to your rig consider the changes in weight and tire size and be sure your brakes are ready to handle your demands.

Lighting- It is important to be able to see obstacles that need to be negotiated close to your vehicle and what is ahead. Proper lighting can make the difference between a fun night ride and a disaster.
