Services

We provide and install Jeep upgrades such as custom jeep axles and lift kits to equip the urban adventurer for the most aggressive offroad experiences.

Jeep Gear Ratio Calculator

Choosing the right gear ratio is one of the most important decisions when modifying a Jeep Wrangler, especially after installing larger tires. A Jeep gear ratio calculator helps estimate how changes in tire diameter, axle gearing, and transmission affect engine RPM, acceleration, towing performance, and overall drivability. Before investing in new gears, understanding these relationships can help ensure your Jeep performs the way you expect both on the road and on the trail. At Mission Custom, we help Jeep owners determine whether regearing makes sense based on their current setup and future plans.

Jeep Overlanding Accessories

Overlanding is about building a Jeep that can comfortably handle extended adventures far from paved roads. The right overlanding accessories improve storage, recovery capability, self-sufficiency, and overall convenience while keeping your vehicle organized and trail-ready. From roof racks and cargo management systems to onboard air compressors, recovery equipment, lighting, and communication gear, every upgrade should serve a purpose.
Mission Custom helps Jeep owners create customized overland builds designed around how they actually travel. Whether you’re planning weekend camping trips or multi-day backcountry expeditions, we can recommend accessories that integrate seamlessly with your existing suspension, lift, wheels, and other upgrades, resulting in a Jeep that’s capable, reliable, and ready for your next adventure.

Whether you’re building an overland rig, tackling technical rock crawling, or simply restoring lost performance after a lift and larger tires, our team can recommend the right gear ratio and professionally install upgraded axle gears to match your driving style.
