4x4 accessories

ATW have designed and developed a range of off road performance accessories for the 4x4 Japanese truck range.

Parabolic Springs

A Parabolic Spring is a spring that consists of two or more tapered leaves. Each leaf represents a complete spring in itself and will act as such. To enable this the leaf is tapered, from the centre (thick) to the outer ends (thin). This tapering is parabolic, which means that every centimetre (or inch) the thickness of the leaf decreases in amount that relates to the square function of it’s length. This is where the thickest part of the spring is mounted to the axle and tapers out to the ends of the spring that mount to the chassis. In between these two points the leaves do not touch each other as they do with conventional springs.This allows each leaf to perform individually rather then one pack of conventional springs.

ATW Parabolic springs increases the vehicle height around 40-50mm (1 1/2-2 inch). You will feel a transformation in the ride quality with a more comfortable, controlled ride. 

The parabolic springs are designed to bolt on to the existing spring mounts of the chassis. Parabolic suspension upgrade kits are available for Isuzu and Mitsubishi / Fuso models.

The design of ATW springs increases the vehicle height around 40-50mm (1 1/2-2 inch) lift and will transform the ride from very harsh to a more comfortable, controlled ride. The parabolic springs are designed to bolt on to the existing spring mounts of the chassis.

ATW have developed a single wheel conversion that is simple yet extremely effective way to improve the ride, look and handling characteristics of a 4x4 truck.

To enhance the capabilities on and off road the ATW single wheel conversion replaces the OEM wheels with ATW rims and tyres which are larger in diametre, wider in width and a larger load capacity. The rims have a offset suited to each vehicle manufacturer.

ATW have developed a single wheel conversion that is simple yet extremely effective way to improve the ride, look and handling characteristics of a 4x4 truck. From factory all of the Japanese 4x4 truck chassis’ come out with dual rear wheels. This means you have 4 tyres on the rear axle and 2 tyres on the front. This is not ideal when traversing through sand, mud and rocky environments.

Auto Torque front Diff centre

Our ATB diff lock is fully automatic and progressive in operation.

Unlike conventional diff locks and LSD’s , ATW’s will never lock. They will seamlessly and progressively transfer power and torque away from a spinning wheel to the one with the most traction. 

Our ATB diff lock is fully automatic and progressive in operation. Unlike conventional diff locks and LSD’s , ATW’s will never lock but will seamlessly and progressively transfer power and torque away from a spinning wheel to the one with the most traction. This is the opposite action of an OEM ‘open’ diff which in soft or loose conditions will promote wheel spin and loss of drive. In off road situations, the ATB diff significantly reduces torque steer, under steer and steering ‘snatch’ associated with common clutched type LSD’s and air or electric diff locks.

When off-road, this translates into reduced wheel spin (improved tyre life), virtually no torque steer and less under steer during cornering.

The ATW Auto Torque Biasing (ATB) Helical Gear Limited Slip Differential (LSD) is a direct replacement for the front axle OEM factory ‘open’ differential centres on all Fuso FG Canters and Isuzu NPS.

Front Bullbar with winch

ATW has developed a range of bullbars that suit various manufacturers and models.

Our most popular is the winch bullbar which is set up to house a recovery winch at the front of the vehicle.

The winch cradle is fabricated out of steel but the main Bullbar component is Aluminium, this helps to reduce the weight over the front axle while still very strong and durable.

Where applicable all winch bars are tested and approved for fitment on airbag vehicles.
