Ironman 4x4 NitroGas 50mm Suspension Lift Kit – Mitsubishi L200 1996–2005

The Ironman 4x4 NitroGas Suspension Lift Kit is a complete suspension upgrade for the Mitsubishi L200 1996–2005, combining Ironman 4x4 NitroGas shock absorbers, heavy-duty front torsion bars, rear leaf springs and the supporting hardware required for a comprehensive suspension upgrade.

Designed around an approximately 50mm suspension lift compared with factory-standard ride height, this NitroGas package is an excellent all-round suspension solution for L200s used for everyday driving, towing, carrying equipment, green laning, overlanding, working applications and medium off-road use.

Unlike a basic lift consisting only of replacement shock absorbers, this package upgrades the key front and rear suspension components. The front uses Heavy Duty torsion bars, while the rear uses replacement Ironman 4x4 leaf springs together with new bushes, shackles, U-bolts and mounting bolts.

Complete Ironman 4x4 NitroGas Suspension System

This package combines the main suspension components required to upgrade the Mitsubishi L200 rather than simply replacing the original shock absorbers.

The configuration includes:

• 2 × 12087GR – Front Ironman 4x4 NitroGas shock absorbers for 0–50mm lift
• 2 × 12698GR – Rear Ironman 4x4 NitroGas shock absorbers for 0–50mm lift

• 1 × 715TUK – Complete greaseable polyurethane bush kit for both rear Ironman 4x4 leaf springs
• 2 × 795 – Greaseable rear spring shackles
• 2 × 387-1 – Non-greaseable spring bolts

Spring selection: where multiple compatible spring specifications are offered on this product, select the appropriate option according to the vehicle's actual permanent load and intended use.

Ironman 4x4 NitroGas Shock Absorbers

This suspension package uses Ironman 4x4 NitroGas shock absorbers at the front and rear.

The kit uses:

• 12087GR – Front NitroGas shock absorber
• 12698GR – Rear NitroGas shock absorber

Both shock applications are suitable for suspension configurations from standard height through to approximately 50mm lift.

Ironman 4x4 positions these NitroGas shocks for medium off-road use, making this version particularly suitable for owners who need a capable suspension system that can combine normal road driving with towing, load carrying, green laning, touring and recreational off-road use.

Why Choose NitroGas?

The NitroGas configuration provides a strong all-round suspension solution for Mitsubishi L200 owners who use their vehicle across a mixture of road and off-road conditions.

It is particularly relevant for vehicles used for:

• Daily road driving
• Towing
• Commercial and work use
• Green laning
• Recreational off-road driving
• Touring
• Overlanding
• Vehicles carrying permanent accessories or equipment

For vehicles regularly subjected to more intensive off-road conditions and prolonged operation over demanding terrain, an Ironman 4x4 FoamCell version of this complete suspension package is also available.

Heavy Duty Front Torsion Bars – MITS015C

The Mitsubishi L200 1996–2005 uses a torsion-bar front suspension system rather than conventional front coil springs.

The kit therefore includes a complete MITS015C set of two Heavy Duty torsion bars.

These replace the original front torsion bars and work together with the NitroGas shock absorbers to provide the required front suspension support and ride-height setup.

Heavy Duty torsion bars are particularly useful on vehicles carrying additional permanent front accessories or operating regularly in demanding conditions.

The final front ride height is established during installation by correctly setting the torsion bars rather than by fitting a fixed-height front coil spring.

Rear Ironman 4x4 Leaf Springs

The rear suspension is upgraded with Ironman 4x4 leaf springs designed to provide increased ride height and improved support compared with worn factory suspension.

Where different compatible rear spring specifications are available, the appropriate spring should be selected according to the actual permanent weight carried by the vehicle and its intended use.

Permanent load can include equipment such as:

• Hard tops and canopies
• Drawer systems
• Tool storage
• Recovery equipment
• Auxiliary batteries
• Camping equipment
• Overland equipment
• Commercial equipment permanently carried in the load bed

Choosing the correct spring specification is important. A spring intended for substantially more permanent weight than the vehicle actually carries can result in an unnecessarily firm ride, while a spring that is too light for a permanently loaded vehicle may not provide the required support.

Complete Rear Spring Installation Hardware

The package includes the supporting components required for installation of the Ironman 4x4 rear leaf springs.

715TUK Greaseable Polyurethane Bush Kit

The supplied 715TUK is a complete greaseable polyurethane bush kit designed for both rear Ironman 4x4 leaf springs.

This bush kit is specifically intended for use with Ironman 4x4 L200 rear springs.

795 Greaseable Shackles

The kit contains 2 × 795 greaseable shackles, providing serviceable rear leaf-spring mounting points that can be lubricated as part of routine suspension maintenance.

451UBK U-Bolt Kits

The package includes 2 × 451UBK U-bolt kits, providing one kit for each rear leaf spring.

U-bolts are critical suspension fasteners responsible for securely clamping the rear axle and leaf spring assemblies together.

387-1 Spring Bolts

The suspension package also contains 2 × 387-1 non-greaseable bolts for the rear spring installation.

NitroGas vs FoamCell

Ironman 4x4 offers both NitroGas and FoamCell suspension configurations for this Mitsubishi L200 application.

The principal difference between these two complete kits is the shock absorber technology.

The NitroGas version is an excellent all-round choice for mixed road use, towing, load carrying and medium off-road driving.

For L200s regularly subjected to more intensive off-road use, prolonged rough terrain or demanding overland conditions, consider the Ironman 4x4 FoamCell 50mm Suspension Lift Kit – Mitsubishi L200 1996–2005.

Kit Contents & Part Numbers

Approximately 50mm Suspension Lift

The suspension package is designed around an approximately 50mm increase in ride height compared with factory-standard suspension.

Actual final vehicle height can vary depending on:

• Vehicle specification
• Existing suspension condition
• Selected rear spring specification
• Permanent accessory weight
• Vehicle payload
• Front torsion-bar adjustment

The quoted lift should therefore be treated as an approximate comparison with original factory ride height rather than a guaranteed increase measured against the vehicle's existing suspension.

Benefits of a Complete Suspension Upgrade

Replacing shock absorbers alone does not restore or increase the spring support of an ageing suspension system.

This complete Ironman 4x4 package upgrades the major suspension components together and can provide benefits including:

• Increased ride height
• Improved ground clearance
• Improved suspension control
• Better support for permanent accessories
• Reduced suspension sag
• Improved control over rough roads and tracks
• Heavy Duty front torsion bars
• New rear leaf springs
• Renewed rear spring mounting components
• NitroGas shock absorbers for mixed road and off-road use

Suitable Applications

The Ironman 4x4 NitroGas suspension package is particularly suitable for Mitsubishi L200 vehicles used for:

• Daily road driving
• Towing
• Commercial and work use
• Green laning
• Medium off-road driving
• Overlanding and touring
• Vehicles carrying permanent accessories
• Camping and recreational use
• Vehicles requiring increased ground clearance

Installation & Suspension Setup

Suspension components are safety-critical, and correct installation and setup are essential.

During installation:

• Inspect chassis and suspension mounting points for corrosion or damage
• Install the Heavy Duty torsion bars correctly
• Set front torsion-bar preload and ride height
• Install the selected rear leaf springs
• Fit the supplied polyurethane bushes and mounting components
• Lubricate greaseable bushes and shackles correctly
• Torque all suspension hardware to the appropriate specification
• Correctly torque the rear U-bolts
• Check brake hoses, ABS wiring and other components throughout suspension travel
• Carry out a complete wheel alignment after installation
• Recheck U-bolts and suspension fasteners after the initial bedding-in period

Professional installation and suspension geometry setup are recommended.

Selecting the Correct Spring Option

Where this product is offered with multiple compatible Ironman 4x4 spring options, choose the spring specification according to the vehicle's actual permanent load and intended use.

Consider equipment that remains permanently fitted to or carried by the vehicle, including canopies, drawer systems, tools, recovery equipment, auxiliary batteries and overland accessories.

Do not automatically select the heaviest available spring. Correct spring selection should balance load support, suspension travel, ride height and ride quality.
