Our Glass House Mountains Workshop
Our fully equipped mechanic workshop in the Glass House Mountains provides professional vehicle modification, certification, and maintenance services to owners across the Sunshine Coast, Moreton Bay, and North Brisbane. As a Queensland-accredited approved person, we carry out and certify a comprehensive range of light vehicle modifications under one roof — from mod plates and 4x4 accessory fitting to engine swaps and compliance work.
The workshop has been purpose-built with the space, tooling, and diagnostic equipment needed to handle complex mechanical projects safely and efficiently. Whether you are bringing in a daily driver for a simple modification or a 4x4 for a full build, our facilities allow us to manage every stage of the job on-site, including final inspection and mod plate issuance.
What We Do
We offer a broad range of mechanical and modification services, all performed and certified in-house by qualified professionals. Every modification that requires a modification plate is assessed and signed off by our accredited approved person in accordance with Queensland Department of Transport and Main Roads requirements.
Mod Plates for Light Vehicles
Our mechanic workshop is one of the leading providers of mod plates across the Sunshine Coast, Moreton Bay, and North Brisbane. We assess, perform, and certify light vehicle modifications, issuing official modification plates that confirm your vehicle meets all applicable Australian Design Rules and Queensland legislation. From straightforward seating changes to multi-stage engine conversions, every mod plate we issue is backed by a thorough hands-on inspection of the completed work.
4x4 Accessories & Parts Installation
We supply and fit a wide range of 4x4 accessories and aftermarket parts at our Glass House Mountains workshop. This includes bull bars, suspension lifts, snorkels, roof racks, long-range fuel tanks, dual battery systems, and lighting upgrades. Every installation is carried out to manufacturer specifications, and where a modification requires certification, we handle the mod plate process as part of the job.
Vehicle Modification Compliance
If your vehicle has been modified — either by a previous owner or at another workshop — and lacks proper certification, we can assess the work and bring it into compliance. Our approved person reviews the modification against the relevant codes of practice and, where the work meets the required standards, issues the appropriate mod plate. If rectification is needed before certification can be granted, we carry out the necessary corrections in-house.
Seating Changes & Reduction — LK1
Under modification code LK1, we perform and certify seating changes including seat removal, addition, and reconfiguration. This service is commonly required for campervan conversions, commercial vehicle fit-outs, and trade-specific builds. We verify that all retained seating positions have compliant seatbelt anchorage and that the vehicle's occupant capacity is accurately reflected on the modification plate.
Child Anchor Point Installation — LK6
Our mechanic workshop installs and certifies child anchor points under code LK6 for vehicles that were not originally fitted with child restraint anchorage, or for new seating positions created during a conversion. Every anchor point is load-tested and certified to meet Australian Standards, providing families across the Sunshine Coast, Moreton Bay, and North Brisbane with confidence in the safety of their child restraint system.
Fuel Tank Change — LM1
We certify fuel tank replacements and upgrades under modification code LM1. Long-range fuel tanks are a popular upgrade for 4x4 owners preparing for remote touring, and replacement tanks are frequently required during vehicle conversions. Our workshop ensures the new tank meets all safety, mounting, and venting requirements before issuing the mod plate.
Transmission Change — LB1
Transmission swaps — including manual to automatic, automatic to manual, and complete gearbox upgrades — are certified under code LB1. We assess drivetrain compatibility, verify correct mounting and alignment, and confirm that the new transmission integrates safely with the vehicle's braking, cooling, and electronic systems. This is a sought-after service among 4x4 owners in the Moreton Bay and North Brisbane regions looking to improve towing performance or off-road capability.
Differential Changes — LB2
Differential modifications certified under code LB2 include ratio changes, limited-slip differential conversions, and full differential replacements. These upgrades improve traction and durability in demanding off-road conditions. We verify compatibility with the vehicle's existing drivetrain components — axles, seals, CV joints, and mounting hardware — before issuing certification.
Equivalent Engine Change — LA1
An equivalent engine change under code LA1 involves fitting a replacement engine with the same or closely matching specifications as the original unit. This is typically carried out when an engine has reached the end of its usable life and a like-for-like replacement is the most practical option. We confirm that the replacement engine matches the vehicle's original power output, emission controls, and ancillary systems before the mod plate is issued.
Performance Engine Installation — LA2
For owners seeking increased power beyond factory specifications, we perform and certify performance engine installations under code LA2. This covers engine swaps where the replacement unit differs from the original in capacity, configuration, or output. Our approved person evaluates the full impact on the vehicle's braking, suspension, cooling, and exhaust systems to ensure the build is both safe and road-legal.
Turbo or Supercharger Installation — LA3
Fitting forced induction — whether a turbocharger or supercharger — to a naturally aspirated engine is certified under code LA3 at our mechanic workshop. This modification demands careful evaluation of the engine internals, fuelling system, intercooling, and exhaust routing. We certify turbo and supercharger builds for vehicle owners across the Sunshine Coast, Moreton Bay, and North Brisbane, ensuring every component is correctly integrated for reliable, road-legal performance.
Why Choose Our Mechanic Workshop
Our Glass House Mountains workshop combines hands-on mechanical expertise with approved person accreditation, giving you access to both the fitting and certification sides of vehicle modification in a single location. This eliminates the need to coordinate between a mechanic and a separate certifier — saving you time, reducing cost, and ensuring continuity of quality from start to finish. Whether you need child anchor points or a full performance engine installation, we handle it all.
We take a straightforward approach to every project: honest assessments, clear communication on timelines and costs, and no shortcuts during certification. Every modification that leaves our workshop carries a legitimate mod plate issued after a thorough physical inspection.
Workshop Tips & Maintenance Advice
Before committing to a vehicle modification, take the time to research whether the change requires a mod plate in Queensland. Driving a modified vehicle without the required certification can result in defect notices, registration issues, and insurance claim rejections. If you are unsure, an obligation-free conversation with an accredited approved person can save you significant hassle down the line. You can also browse our mod code reference guide or use our vehicle modification checklist to determine what certification your modification requires.
For 4x4 owners, regular inspection of aftermarket accessories — particularly suspension components, bull bars, and long-range fuel tanks — is essential to maintaining both safety and compliance.
