What We Do

Our off-road & overlanding upgrade services include (but are not limited to):

Suspension & Undercarriage

  • Heavy-duty suspension systems (lift kits, upgraded shocks/struts, control arms) tailored to your vehicle, terrain, and usage.

  • Reinforced mounting points and frame-compatible upgrades to preserve structural integrity.

Drivetrain, Axles & Off-road Components

  • Upgraded differential covers, locking differentials or lockers, reinforced axle shafts to handle increased loads.

  • Upgraded tires/wheels (all-terrain, mud terrain), tire pressure monitoring systems, beadlock options (depending on rig).
  • Recovery gear integration: winches, recovery hitch, anchor points, hitch-mounted recovery tools.

Overlanding Specific Builds

  • Auxiliary power (dual battery systems, solar panels, in-vehicle inverter setups).
  • Off-grid lighting: LED light bars, off-road flood/spot lights, interior/gear lighting.
  • Storage and organization: heavy-duty racks, gear lock-boxes, water/air/gear mounts.
  • Camping lifestyle upgrades: on-vehicle fridge/freezer integration, awnings, exterior shower/systems.

Our practice

Why this makes difference

Durability

Trail-driving, rock crawling and overlanding place major stress on a vehicle. Our upgrades factor in structural reinforcement, proper suspension geometry, and long-term reliability.

Safety

Proper mounting, frame integrity, alignment, break points, recovery integration: an improperly modified vehicle can be a liability.

Resale value

A professionally built and well-documented overlanding/4×4 upgrade will help retain value compared to piecemeal or DIY builds.

Convenience

Instead of coordinating multiple shops (fabrication, suspension, accessories, wiring), you get a turnkey solution in one trusted facility — the same one that already provides collision/repair services.

One Stop Shop

From paint/finishes to mechanical upgrades to accessory wiring and installation, we have the breadth of services needed to build a complete off-road rig.

Who this is for

  • Enthusiasts building weekend trail vehicles: rock-crawlers, desert runners, sand dune rigs.
  • Families and adventurers converting vehicles into overland rigs for camping, remote travel, and rugged terrain.
  • Owners who’ve sustained damage during off-road use (scrapes, frame hits, bent suspension) and want a rebuild/upgraded solution.
  • Anyone wanting to upgrade a standard SUV/4×4 platform into a custom adventure vehicle, while preserving safe and reliable usage on and off road.

Our build process

  1. Consultation & Planning – We begin with what you intend: terrain type, trailer or no trailer, number of passengers/campsite gear, expected budget.
  2. Design & Quote – We create a build plan, list components, structural reinforcements, timeline, integration points (e.g., wiring, custom brackets).
  3. Installation & Integration – From frame up modifications to finishing touches (paint, bed liner, accessories), we handle it all in-house or via trusted partners.
  4. Testing & Alignment – Off-road build testing, alignment checks, load-test, safety check of recovery points, final inspection.
  5. Delivery & Support – You receive a full rundown of installed parts, recommendations for maintenance, and if applicable a warranty on our workmanship.
