A clear answer.
For your next build decision.
Tell us what the vehicle needs to do. We review suitable options, check the available evidence and explain the trade-offs in writing, including when the right choice is to buy less.
We agree the scope and price before work begins.
You’ll probably enjoy working with us if…
- You want a 4WD that suits the trips you actually take.
- You appreciate an honest “you don’t need that”, even when you had your heart set on it.
- You want to understand why something suits your vehicle before spending your money.
- You’re happy to build in stages when that makes better use of your budget.
- You value advice that takes your plans seriously and is willing to challenge your assumptions.
You don’t need to arrive with all the answers. Knowing what you want your vehicle to do is a good place to start.

And a clear next step
Advice you can come back to as your build takes shape.
A question we agree on
Your vehicle, your plans and a clear scope, with the price agreed up front.
The reasoning in writing
Suitable options, the trade-offs and why the recommendation fits your situation.
What to do next
Practical next steps, with assumptions and checks still needed before you buy.

Illustrative advice output
What a written answer contains.
Synthetic demonstration only. No customer, completed engagement, measurement or exact product recommendation is represented.
The question
“I have been quoted for a heavy front-protection package. Do I need it for weekend camping and daily driving?”
Vehicle and use
An illustrative dual-cab 4WD used for commuting and weekend trips. Exact year, engine, configuration, current axle masses and towing requirements still need confirmation.
Options considered
- Keep the current setup: adds no new accessory mass or purchase cost; assess whether it meets the intended use.
- Investigate a lighter assembly: compare protection requirements, fitment restrictions and the complete installed mass.
- Investigate a heavier winch-compatible package: justify the recovery requirement and confirm all mounts, sensors, cooling and winch components.
Recommendation and reasoning
Defer ordering until the intended function, exact fitment and available axle capacity are established. If the current setup meets the use case, retain it. Otherwise compare the lightest evidenced option that meets the confirmed requirement; price alone cannot answer this question.
Weight consequence
Illustrative arithmetic: a complete 70 kg assembly replacing 25 kg of original equipment adds 45 kg net. These are invented demonstration inputs, not weights for a real vehicle or SKU. Unknown removed mass means the net addition remains unknown.
Before a final recommendation
- Confirm the exact vehicle identity and manufacturer application guide.
- Obtain full assembly mass and the original-equipment mass being removed.
- Measure the loaded vehicle and individual axles; compare the applicable ratings.
- Check compatible mounts, recovery points, driver-assistance sensors and installation instructions.
- Confirm any modification approval, insurer or warranty questions with the responsible provider.
Evidence and limits
A real report links the exact vehicle specification, SKU/application guide and instructions. None is asserted here. General modification process: Australian Government VSB 14; administration remains jurisdiction-specific. Source checked 13 September 2026.
Your next actions
Send the vehicle details, quoted part numbers, intended use and any existing weight tickets. We confirm the scope and quote, then complete the research. No purchase or installation is booked by this enquiry.

Compare the scope before choosing. Every package produces a written answer or report; it does not book an installation or certify a modification.

Target turnaround starts once the scope is accepted and the necessary information and any deposit are received. Supplier delays and the agreed delivery date are confirmed with your quote.
Articles, comparisons, calculators and account Garage are free in the Launch Edition. Optional membership requires a later approved release after the audience threshold is met. Personal advice is a separate, quoted service.
Built around the job.
Ready for the next decision.
Independent vehicle planning for contractors, mine-spec light vehicles and working fleets. Turn your site requirements into a clear build specification, weight assessment and scope your fitters can quote against.
From requirements to a quote-ready scope
Specify the vehicle
Match the vehicle and equipment to the work, site requirements and intended loads.
Understand the limits
Review payload, axle and towing figures, with assumptions and outstanding checks clearly recorded.
Compare like-for-like quotes
Give fitters a consistent written scope so you can compare the same proposed build.
Scope, deliverables and fees agreed before work starts. Independent planning and research; installation and engineering certification are arranged separately.
Independent research
Research that remains accountable to you.
Recommendations follow your needs and the available evidence. We explain the reasoning, identify material commercial interests and retain editorial control. Commercial support cannot buy a favourable technical conclusion.
FitFourby may later offer optional paid services or commercial collaborations. Any paid visibility would be labelled and kept distinct from ordinary directory results and technical recommendations. Payments, affiliate interests, gifts, loans, discounts and co-produced content would be disclosed beside the relevant content or recommendation, including support involving products, services, events or vehicles. No such arrangement is being announced here.
Standard directory listings and referrals are free at launch. After your filters, current directory results are grouped by state, then ordered by postcode. Installer status and authorised-dealer status are distinct; confirm current scope and authorisation directly with the business.
The catalogue covers the vehicles and products researched so far. Catalogue presence does not establish exact fitment, current publication approval or supplier stock. No verified match does not mean no compatible product exists.
When quote research is included
Any negotiated saving is yours. A discount is not guaranteed and does not change our fee or a workshop’s position in the directory. You decide whether to accept a supplier’s quote and contract with them directly. Read the scope and service terms →
Advice supports product and build decisions. It does not certify safety, legality or compliance.
Limits of this advice
Important: FitFourby's advisory work addresses the vehicle, intended use and question agreed in your proposal. It is not engineering certification, legal advice, insurance advice, roadworthiness approval, or a guarantee of compliance. 4WD modifications may affect road legality, insurance cover, factory warranty, GVM, towing capacity, ESC systems, payload, and other vehicle specifications. Customers should confirm legality, insurance implications, warranty impacts, and certification requirements with the relevant manufacturer, installer, engineer, insurer, and state transport authority before proceeding with any modification.
