TJM XGS Suspension

For more than 50 years, TJM and its products have been a leading manufacturer of 4WD chassis in Australia. The XGS suspension components are manufactured in Thailand in TJM's own factories. Over that time, TJM has gained valuable expertise in the design, testing, manufacture and installation of undercarriages for 4WD vehicles and light commercial vehicles. A given is the rigorous testing of XGS components on vehicles under heavy loads driving on Fraser Island, the immensity of the Simpson Desert, Cape York, the Canning Stock Route and the High Country of Victoria. The TJM XGS chassis also withstand the very high loads in deserts such as the Sahara, Empty Quarter (Saudi Arabia) or Dash De Lut (Persia). Many customers will probably never encounter the extreme conditions experienced during our testing, but it is important to know that TJM XGS suspension is designed and manufactured to withstand some of the toughest conditions encountered in vehicle operation around the world. We believe the results speak for themselves. XGS chassis offer the highest ride quality and driving stability, high possible payload, improvements when towing a trailer. This results in a high level of safety and more comfort when driving the 4WD. That's why choosing a TJM XGS chassis is a wise choice for the 4WD driver who cares about optimal driving performance on the road, track or off-road. In Switzerland, the chassis are offered with a declaration of suitability or a DTC report with a 3.5t load increase (Hilux, Prado, Ranger, Amarok).

Four reasons for installing an XGS 4WD suspension

Improvement of the road situation and damping of unevenness
Sufficient ground clearance and the wheel suspensions are critical sizes for 4WD vehicles, which justify the installation of an XGS suspension. The suspension thus retains the necessary travel and the XGS shock absorbers reduce the spring vibrations, so that the wheels keep the ground contact.
Improves ride comfort and handling of the vehicle
The incorporation of XGS springs and shocks significantly improves ride comfort and handling, loaded and unloaded on the road, runway and off-road.
Improved handling when heavily loaded or when towing a trailer
Supports driving in heavy payload or pulling trailers without sacrificing good ride comfort.
Safer driving
A well-designed and tuned chassis provides the highest level of vehicle safety for drivers, passengers and other road users.

COIL SPRINGS

XGS Suspension linear and progressive rate coils are manufactured to TJM’s exact specifications on computer controlled coiling machines, then shot peened, load tested and powder coated. Designed to provide a smooth comfortable ride when the vehicle is empty and improved stability and load carrying ability when the vehicle is loaded. Choose from standard height, raised, heavy duty or extra heavy duty hi-lift kits with XGS Series 4000 Coil Springs.

LEAF SPRINGS

Leaf springs are considered by some to be harsh riding, and often sag with age or when under constant load. XGS resolves these problems with heavy duty springs of multi-leaf design. Ride comfort is improved by the integrated glider pads. Australian and Thailand made, using high grade BHP steel, each spring is pre-stressed to eliminate the possibility of sagging. These springs are available in either medium, heavy duty or extra heavy duty load rating.

U-BOLTS

XGS U-Bolts are matched in length to the increased stack height of the XGS Leaf Spring range and should be used when installing XGS Leaf Springs.

POLY BUSHES

XGS Polyurethane Bushes are a high grade component manufactured specifically for 4WD applications and offer a far longer life than rubber bushes.

GREASEABLE SHACKLES AND PINS

Available for most leaf spring vehicles, XGS Greaseable Spring Hangers and Pins are are standard heavy duty components, made to exact tolerances and nickel plated for long service life.

TORSION BARS

Torsion bars are the spring design used on the front of many two and four wheel drive vehicles. While providing excellent ride quality, some vehicles fitted with torsion bars may suffer in their ability to carry loads, and nose-dive under braking which results in loss of ground clearance. XGS front torsion bars are available as an upgrade to improve a vehicle’s load carrying ability and stability. XGS heavy duty torsion bars are usually supplied in larger diameter than the original unit, increasing spring rate which ensures ride height ismaintained and vehicle handling both on and off road is improved.

STEERING DAMPERS

An ideal replacement for the original damper when worn out or damaged. Available in 35 mm, with improved quality components, larger piston and bore diameters and up to 100% increase in oil capacity over most original units. This 35 mm big bore steering damper offers awesome control in harsh conditions, but is available for a limited range of vehicles only. This damper this unit is installed in place of the original damper.

PANHARD RODS

Adjustable Panhard Rods are used when a vehicles suspension is raised to re-centre the differential and balance the vehicle back to original specifications

UPPER CONTROL ARM

The Upper Control Arms are made to be installed in combination with a raised offroad TJM Suspension kit with a lift from +35 to +50mm such as Series4000, XGS or Remote/Pace. The integrated 3° castor correction allows now a correct wheel alignment following the car manufcturer's settings.

Strait driving and no wear of tires is a result.
