Suspension

Suspensions

Suspension is not something you often see when you first look at a vehicle. 

But when you need it suspension is the single most important upgrade you can make to your vehicle.

Original equipment suspension is set up to support your vehicle for on-road conditions with a reasonable amount of weight. When you start to add vehicle accessories, attach a trailer or caravan and increase your load, the way the suspension handles the load changes. Couple that with uneven surfaces and off-road conditions, the OEM suspension can no longer take the additional strain.

Suspension Kits

Ironman 4×4 offer a complete integrated range of suspension kits, designs which have evolved over 50 years of suspension experience.

Ironman 4×4 recognise that there is no single solution practical for the varying needs of 4×4 owners and different driving conditions, therefore Ironman 4×4 offer a wide selection of matched components, once fitted will transform the vehicle around the drivers needs.

WHAT DO YOU GET?

ALL LEAF SPRING KITS CONTAIN: Springs, Shock Absorbers, Ubolts and Bushes. 

ALL COIL SPRING KITS CONTAIN: Springs and Shock Absorbers.

Ironman 4x4 also offer various optional components further enhancing suspension performance or geometry correction purposes. Such components include Greasable Shackles & Pins, Steering Damper, Caster Correction, Trim Packers, Suspension Arms.

Coil Springs

Ironman 4x4 produce a wide range of coil springs to suit a range of load ratings, all designed to maintain optimum ride height.

Coils springs produced by Ironman 4x4 undergo class leading manufacturing processes to ensure the highest possible quality, including:

CNC COLD COILED -

All Ironman 4x4 coil springs are CNC Cold coiled to ensure perfect consistency and accuracy. The result of cold coiling means that springs are subjected to less heat during the manufacturing process to help maintain the materials properties and resulting in longer life.

BAR PEELED –

Bar peeling is the process of forming the material to an exact size before coiling. This ensures the diameter remains constant and free of flaws along its entire length.

SHOT PEENED –

Manipulates material surface tension to reduce stress, greatly enhances spring life.

TRIPLE SCRAGGED –

Each coil is fully compressed to a solid state 3 times to minimise coil settling.

PROGRESSIVE AND LINEAR RATE –

Used in accordance to original vehicle manufacturers preference, progressive springs increase rate as the spring compresses, linear springs maintain a consistent rate throughout its range.

POWDER COATED –

All springs are electro-static powdercoated for a durable finish.

Leaf Springs

Ironman 4x4 produce a wide range of Leaf Springs to suit a range of load ratings, all designed to maintain optimum ride height.

Leaf Springs produced by Ironman 4x4 undergo class leading manufacturing processes to ensure the highest possible quality including:

INTER-LEAF LINERS –

Used in some applications to lower friction between leaves reducing noise and improving comfort.

LINED BOLT CLAMPS –

All Ironman springs feature bolted guide clamps for greater flex, the addition of anti-friction liners ensures noise free smooth operation.

SHOT PEENED –

Shot peening manipulates the spring materials surface tension to reduce stress and will enhance the springs life.

DIAMOND CUT LEAVES –

Distributes load at the leaf tip and reduces interleaf friction.

MILITARY WRAP –

Where applicable, an additional wrap around the leaf eye protects from failure in case of damage.

Pro-Forge Upper Control Arms

Ironman 4x4 Pro Forge Upper Control Arms allow installation of larger tyres and further increased ride height by providing corrected wheel alignment and greater operating clearance around the arm as is often the limitation when using the OEM upper control arms.

The Pro-Forge Upper Control Arms, are manufactured from 6082 T6 alloy with silver anodised corrosion protection. Ultimate strength is achieved using a drop forged method of construction that hammers the arm into shape using a precise die. During this process the grain structure of the alloy is aligned with the new shape and any imperfections are removed.

This results in a much stronger and more durable product than a cast, machined or fabricated arm.

Low maintenance components which follow the OEM philosophy ensure durability is not compromised.

Bushes and ball joint are replaceable with OEM compatible or Genuine components.

All fixtures including brake wire provision are integrated within the arm.

ADR compliant with a 3 Year 60,000km warranty.

  • Optimise Wheel Alignment at Raised Ride Height
  • More Clearance for Larger Tyres and Increased Lift

Tomcar Australia

Tomcar Australia

Since 2011, Ironman 4x4 was the official suspension supplier to Tomcar Australia. However, in 2017 the off-road all-terrain vehicle manufacturer Tomcar Australia went into voluntary administration, closing its Melbourne based production facility.

Following Tomcar Australia's shutdown, Ironman 4x4 is releasing the remaining stock of genuine suspension components for sale as spare parts for the existing Tomcar population around the country.

Stock is made available via the Ironman 4x4 distribution network.

The current stock of suspension / shock absorbers is the latest generation, and can be retro-fitted to all Tomcar Australia built vehicles.

GVM Upgrades

The usable payload of many 4x4 vehicles today is minimal. Additional basic optional equipment along with two or three adult occupants will bring the vehicle close to its legal maximum weight (GVM) in many cases. Add long range fuel tanks, bull bars, winches, side steps, roof racks, recovery gear and a payload of camping equipment or an industrial type custom body and the vehicle will ultimately exceed the Original Equipment allowable Gross Vehicle Mass.

Original Equipment suspension is designed for comfort above all other considerations, thus load carrying and performance can be compromised. Whereas, Ironman 4x4 GVM upgraded suspension systems come with matched components for the ultimate in performance, load carrying and handling.

Ironman 4x4 products are extensively tested in real world conditions, both in-house and by independent automotive engineers to ensure conformity and operator comfort.

Ironman 4x4 regularly maintains and reviews its own internal processes and procedures as part of our ISO 9001 Quality Management System certification.

Formal testing verifies product safety and performance through official certifications issued by independent testing agencies and Government departments, including DOTARS, TÜV Nord and KBA.

Adjustable Trailing Arms

Trailing arms are some of the most exposed suspension components on a lifted 4x4 and are prone to bending and breaking. Ironman 4x4 has resolved this common problem by producing heavy duty ADR approved, adjustable upper and lower trailing arms to suit GQ/ GU Patrols and 80/105 Series Landcruisers.

Providing radically stronger arms that can also correct driveline and pinion angles, the control arms feature over 5” of adjustment to suit a range of lifts and applications. The arms are on-vehicle adjustable, providing ease of adjustment once on the vehicle to ensure diff alignment is spot on!

Oh and did we mention they were tough? Featuring a solid 32mm centre, 60% increase in the thickness of the eyes surrounding the bushes and deeper penetrating welds to ensure maximum strength and structural integrity.
