HEIGHT ABOVE SEA LEVEL

What's silver, drinks diesel, whistles while it works and casts shadows on road trains?

Words by Glenn Wright, photography by Robb Cox

Mathew and Tina Zammit's high-riding 80 Series LandCruiser is built like a house in a flood zone, sitting 8in higher than Toyota's engineers ever signed off on. While this allows the oversized oiler to get over the odd boulder or three, the downside is that as the Zammit family's only form of transport, it is employed full-time as a daily driver, shopping cart and school bus. The laughs flow thick and fast when Tina hops down from this skyscraper to kiss her kids goodbye outside the local school. You see, Tina tops the height chart at a massive 5ft 1in. This means that the only time Mum gets to see the top of the bonnet is while keeping the driver’s seat warm, but she wouldn't have it any other way.

When the lofty LandCruiser has finished all its domestic duties, it’s rewarded with hardcore trips to Mathew's favourite haunts in the Watagans, Hampton and Yalwal to stretch its weary springs. Mathew spotted the bog-stock Toyota in a used-car yard and chose it over the Patrol because of Toyota's habit of dotting the Is and crossing the Ts when it comes to build quality and creature comforts. It’s a decision he doesn't regret after receiving many SOS calls from mate Peter over the UHF to come and drag his Patrol out of trouble.

Peter Noone, from Xtreme 4X4 Services, shares Mathew's passion for doing it in the dirt. The two put their heads and talents together - when they weren't locking horns over the Nissan vs Toyota debate - to successfully create the tall Toyota over six months, completely ‘in house’, under the Zammit's carport in Sydney. Mathew would like to thank his wife Tina for turning a blind eye in relation to the expense and time spent getting it right. Maybe Tina should thank you, Mathew, seeing as she gets to enjoy the fruits of your labour five days a week.

SUSPENSION
The ‘Cruiser that towers over you in the car park today is the result of 12 months of work. What started out as a 4in lift to accommodate a set of 33s blew out, as all good projects do, to an 8in suspension lift with all the necessary geometry changes to keep the truck stable on 35in MTRs. Searching through the ads in 4WD Action, Mathew came across a set of Dobinsons coil springs, which provide the massive jump in ride height. Because the body retains its standard height above the chassis, all the lift is taken care of by the springs and their extended mounts on the diffs.

Once you stray from the original design of a truck's suspension, as any hardcore 4WD addict does, you open up a Pandora's box. Fitting much longer coils means that longer everything must also be added to maintain necessary suspension travel and steering geometry. Longer fabricated mounts hold in place Rancho 5000-series shocks that were necessary to replace lost suspension droop.
Care must be taken when choosing shock lengths to avoid too long a shock absorber, which will limit your travel in the upward direction. A tip here is to choose shock absorbers last, after moving your modified suspension up and down through its desired range of travel. Measure the total closed length and maximum extended length of your shocks to see which will suit best. Longer Panhard rods were fitted to allow the diffs to remain central to both wheel arches, and the swaybar links were also lengthened.

The only real ‘oops’ in this extreme makeover was noticed in the steering. A common mistake in lifted trucks with solid front axles is that when the front diff is ‘twisted’ to allow for steeper tail-shaft angles, the castor is reduced. Mathew noticed the wandering, boat-like steering on his maiden voyage in the lifted LandCruiser and soon relocated the front lower arms to increase the castor angle.

DRIVELINE
Other casualties resulting from the suspension lift were the replacement of the front and rear propshafts. The custom-made front shaft incorporates a double cardan joint (basically two uni-joints in sequence) to allow the shaft to operate through a greater angle. Both propshafts were remade using thicker-walled tube than the originals. The rest of the manual transmission and 4WD system got away scot-free, save for the diffs.

The standard front diff cried enough several years ago, which led to the fitment of front and rear ARB Air Lockers. Mathew reckons his Toyota owes a lot of its off-road ability to these proven gizmos, having towed far too many vehicles out of sticky situations that weren’t fitted with these must-haves. The standard 4.2L turbo-diesel has proved reliable over the past 235,000km, so Mathew set out to test its pulling power by hooking it up to his new 23ft, 3t Whitley cruise boat. He was surprised at how well the diesel hairdryer combo coped, but as we are learning, Mathew always wants more.

This saw the truck's turbo tweaked for more boost (he won't tell how much) and bigger injector nozzles along with some pump work. The Safari Snorkel keeps this tall customer in constant supply of clean, dry air, though because of the air filter's height above sea level, I doubt much water could get near the airbox anyway. The gasses left over after the engine's done with them are fed rearwards via a twin-pipe 2.5in mandrel-bent exhaust system.

EXTERIOR
Wrapped in an ARB steel winch bar complete with side and sill bars, the ‘Cruiser's body panels remain fairly standard in silver livery. Beneath the smooth exterior body panels hides a sad tale. While enjoying a boys’ weekend away at Oberon, Mathew thought it wise to take off down a steep incline in the ‘Cruiser with the shocks set to fully soft. I can't say what spurred him on; you can make up your own mind. Anyway, waiting at the bottom of the hill was a deep ‘V’ gutter, which the 4WD, complete with Mathew inside, bounced out of. It was then that a large tree jumped out in front of them causing $12,000 damage to the vehicle. The upside to this was that the vehicle received a complete respray and now looks 100-percent.

EXTRAS
Electrically speaking, all the airwaves are covered, with an AM GMC TX835, UHF GMC TX4400 radio and a Pioneer stereo. Casting light on the subject is a pair of Narva bull lights and two Hella spread beams. Mathew and Tina have a short wish-list for this tall truck. It includes a twin-battery set-up, possibly a winch, oh, and a set of 37s. Otherwise, they love their daily driver, as it does everything asked of it and comes back for more.
They are very appreciative of the help from Global Auto Electrical (02) 9623 4878, St Marys Prestige for the panel work, and their good friend Peter Noone from Xtrem 4X4 Services 0410 865 004.
