RHD Conversion Checklist: What to Check Before Buying a Converted American Truck

Why RHD conversion quality varies so much

Almost every full-size American truck sold new in Australia — RAM, Chevrolet Silverado, GMC Sierra — starts life as a left-hand-drive vehicle built for the US market and is converted to right-hand-drive here or before import. The engineering behind that conversion ranges from genuinely excellent, factory-integrated work through to conversions that cut corners in ways that aren't obvious on a test drive.

Because the truck still looks and feels largely like the original vehicle, buyers often assume the conversion is a minor detail. It isn't. The steering rack, brake pedal box, wiring harness relocation and dashboard electronics all have to be re-engineered, and the quality of that work affects safety, reliability and resale value for as long as you own the truck.

Compliance paperwork to check first

• A compliance plate confirming the vehicle meets Australian Design Rules (ADRs)
• Documentation showing the conversion was carried out by an RAWS (Registered Automotive Workshop Scheme) approved converter or under the current equivalent import scheme
• Engineering certification for the specific conversion, particularly for steering and braking systems
• A build or compliance date that matches what you're being told about the vehicle's history
• State registration history that's consistent with a properly compliant import, not a private or grey import with gaps

If a seller can't produce clear compliance documentation, that's a reason to walk away or, at minimum, get independent verification before proceeding. Non-compliant or poorly documented conversions can create real problems at registration renewal, insurance claim time, or resale.

What to physically inspect on the truck

Steering conversion

The steering rack, column and linkage all need to be converted to work from the right side. Check for even, consistent steering feel with no unusual play, binding or noise when turning lock to lock, and have a workshop check the geometry and mounting quality rather than relying on how it feels on a short test drive.

Brake pedal box and master cylinder

This is one of the more safety-critical parts of any conversion. A well-executed conversion should give a firm, consistent pedal with no sponginess or delay. Any hesitation, inconsistent bite point or unusual pedal travel warrants a proper inspection before purchase — this isn't a system to take on trust.

Dashboard, wiring and electronics

The dashboard, instrument cluster and associated wiring loom are relocated as part of the conversion. Test every switch, gauge and warning light, along with any driver-assist features like adaptive cruise, lane-keep assist and blind-spot monitoring — these systems rely on sensors and wiring that can be affected by a lower-quality conversion. A dash full of warning lights or intermittently working features points to shortcuts in the electrical work.

Pedal box and driver ergonomics

Beyond the brake pedal specifically, check accelerator pedal feel, seating position relative to the new pedal box, and footwell clearance. Poorly executed conversions sometimes compromise these for the sake of getting components to fit, which affects comfort and, in some cases, safe pedal operation.

Get an independent pre-purchase inspection

The seller's own paperwork and word are a starting point, not a substitute for an independent check. A pre-purchase inspection by a workshop that regularly works on converted American trucks will pick up on conversion-specific issues that a general mechanic or standard used-car inspection may not know to look for. This applies whether you're buying from a dealer or privately, and is worth the cost regardless of how good the truck looks.

What else to check on a used American truck

Beyond the conversion itself, the usual used-truck checks still apply — engine and transmission health, service history, evidence of towing overloading, and tyre and suspension condition. Our general buying checklist covers these in more detail and complements the conversion-specific checks here.
