01 · Product gallery

Gear that works.

We stock ARB, Old Man Emu, Warn, Ironman 4x4 and Opposite Lock — nothing we would not bolt to our own rigs. Every product is fitted in our Kahikatea Drive workshop by qualified technicians.

02 · Vehicle compatibility

Does it fit?

We keep fitment templates for every common ute and 4WD sold in New Zealand. If your vehicle is not listed, ring us — we can usually source or fabricate brackets in-house.

05 · Fitment process

How we build.

  1. Consultation

    Walk-in or phone. We ask about your vehicle, what you use it for and your budget. You leave with a written quote — no pressure, no rush.

  2. Measurement & ordering

    We check your vehicle against our fitment database and confirm every bracket, bolt and trim piece. Parts from ARB, OME and Warn are usually in our warehouse; custom items take 10–14 working days.

  3. Fitting day

    Most bull bar and suspension jobs are a single day. Full builds (bar, lift, winch, canopy) typically take two days. We provide a courtesy vehicle for builds over four hours.

  4. Quality check

    Every bolt is torqued to spec and photographed. We do a 20-point alignment check after suspension work and a full electrical test after lighting and winch wiring.

  5. Handover

    Walkaround video, fitting certificate, warranty registration with the manufacturer and a 500 km re-torque reminder. Lifetime workmanship warranty begins today.

06 · Common questions

Straight answers.

What does the lifetime workmanship warranty cover?

It covers our labour and any fastener or bracket we supply for as long as you own the vehicle. It does not cover the product itself — that is covered by the manufacturer's warranty (ARB is five years, Warn is limited lifetime, OME is three years). If a bolt loosens or a bracket cracks because of how we fitted it, we fix it free.

How long does a bull bar fitting take?

A straightforward bull bar swap is three to four hours. If we are adding a winch at the same time, allow five to six hours. We book one vehicle per bay per day so yours gets our full attention.

Will a 2″ lift affect my warranty?

A well-engineered lift using quality components generally does not void your manufacturer's warranty. We use OME kits designed to maintain correct suspension geometry. We also provide a fitting certificate that your dealer can refer to if questions arise at service time.

Do you do WoF and cert work?

We do not issue WoFs ourselves, but we work with two VTNZ-certified inspectors in Hamilton who are familiar with our builds. If you need a Low Volume Vehicle certification for lifts over 2″ or non-standard lighting, we can arrange that as part of the build.

Can I supply my own parts?

We prefer to supply parts because we can guarantee compatibility and warranty coverage. If you have already purchased parts, we will fit them at our standard labour rates but cannot extend the workmanship warranty to components we did not source.

Do you ship nationwide?

We are a fitting workshop, not a parts retailer. For customers outside the Waikato we recommend visiting your nearest ARB or OME dealer. However, if you want to drive your rig to us for a full build, we can arrange accommodation at a partner motel in Frankton.
