What’s the first upgrade I should do to my 4WD?

By

Fuel. Then use the thing. The first real upgrade depends on where the standard vehicle lets you down—not what the loudest bloke in the car park fitted last Thursday.

Start with the trip, not the catalogue

A beach car may need a compressor, pressure gauge and recovery points before it needs suspension. A remote tourer may need communications, water and tyre reliability. A work ute may need load-rated suspension after the actual constant load is known. A daily driver that visits easy campsites may need nothing beyond good tyres and recovery basics.

Wheels and a lift are not a personality starter pack. Larger tyres alter gearing, braking and fuel use. A lift raises the centre of gravity and does not increase clearance under the differential.

A sensible first-spend order

  1. Maintenance and a baseline inspection.
  2. Training, tyre gauge, compressor and basic safety equipment.
  3. Rated recovery points and appropriate recovery equipment for the trips you take.
  4. Tyres when the originals are unsuitable or due for replacement.
  5. Only then, the modification that solves a demonstrated problem.

If you cannot say “I need this because…”, keep the money. The vehicle will eventually tell you what it needs, usually right after an accessory shop has told you it needs everything.

Choose the guide that matches the job

Camping · Touring · Overlanding · Towing · Trade · Hard wheeling

Check modification legality, insurance, warranty, payload and axle effects before buying.
