MLO's New Shop Vehicle Build Phase 1 — Lexus GX 550 Overtrail

The new Lexus GX550 is quickly becoming one of the most sought after platforms in the overlanding world, and for good reason. Combining Toyota’s reliability, luxury refinement, and serious off-road capability, the GX550 is a perfect foundation for an adventure vehicle. It offers Full time 4WD, locking rear differential, Modern off-road technology, turbocharged performance, and exceptional reliability.  With the right modifications, it becomes one of the most capable and comfortable overland SUVs on the market.

At Main Line Overland we recently transformed our shop Lexus GX 550 Overtrail Edition into a fully trail-ready overland build.  This build reflects how we approach every customer project at Main Line Overland: functional upgrades, premium components, and professional installation designed for real-world adventure.

Here’s a complete breakdown of the modifications during Phase 1 of this build. 

GX550 Suspension Upgrade: King Shocks

A proper overland build starts with suspension.

We installed King Shocks to improve ride quality, off-road performance, and durability under load. King’s performance coilovers provide:

Increased suspension travel

Better damping over washboard and rocky terrain

Improved handling with added armor and gear

Rebuildable, race-proven reliability

For a vehicle like the GX550, upgraded suspension is essential when adding bumpers, larger tires, and overland equipment.

High Clearance Protection: Dissent Off-Road Front Winch Bumper

Approach angle matters when navigating technical terrain.

We equipped the GX550 with a Dissent Off Road High Clearance Front Winch Bumper. This upgrade provides:

Improved approach angle

Integrated winch capability

Increased front-end protection

Aggressive, functional styling

A winch bumper is one of the most practical GX550 mods for overland travel, offering both recovery capability and durability in rocky environments.

Method 703 Wheels + BFGoodrich KO2 Tires

No overland build is complete without upgrading wheels and tires.

We paired Method Wheels 703 with BFGoodrich KO2 tires — a proven combination in the overland community.

Method 703 Wheels

Bead Grip® technology for running lower tire pressures

Strong, lightweight construction

Trail-tested durability

BFGoodrich KO2 Tires

All-terrain traction (dirt, snow, rocks, mud)

Reinforced sidewalls

Long tread life

This wheel and tire combo gives the GX550 a wider stance, improved off-road grip, and the rugged look expected from a serious overland vehicle.

Baja Designs LED Lighting Upgrade

We installed premium lighting from Baja Designs, dramatically increasing nighttime visibility and safety. Whether navigating forest roads or setting up camp after dark, high-output LED lighting is an essential upgrade for extended overland trips.
