Fuso FG649-637 TM Suspension Fitted F & R Upgrade Multi Leaf+ Remote Cs

The AAV4x4 Trackmaster Suspension Upgrade is a premium heavy-duty suspension package developed specifically for Fuso FG637, FG649 and compatible Canter 4x4 models that spend their lives carrying serious loads and travelling long distances on Australia's toughest roads and tracks.

Professionally supplied and fitted by AAV4x4, this complete front and rear suspension upgrade combines heavy-duty multi-leaf spring packs with premium Trackmaster three-way adjustable remote reservoir shock absorbers. The result is improved vehicle control, increased load carrying confidence, better ride quality over corrugations and greater suspension durability for demanding touring and expedition applications.

Unlike generic replacement suspension, the Trackmaster system has been developed specifically for heavy 4x4 light trucks where reliability, suspension control and serviceability are critical. The package is the result of extensive real-world testing across remote Australian conditions and forms part of many AAV4x4 expedition vehicle builds.

Trackmaster Remote Reservoir Shock Absorbers

The heart of the system is the Trackmaster remote reservoir shock absorber package. These premium dampers are fully rebuildable and feature independent adjustment of high-speed compression, low-speed compression and rebound damping, allowing the suspension to be tuned to suit vehicle weight, terrain and driving style.

• 10-stage high-speed compression adjustment
• 20-stage low-speed compression adjustment
• 15-stage rebound adjustment
• Remote reservoir design for increased oil capacity and cooling
• Fully rebuildable for long-term serviceability

Premium Shock Construction

Trackmaster shock absorbers are built using high-quality internal components designed for demanding off-road use and heavy vehicle applications.

• 50/60mm CNC-machined high-flow billet aluminium race piston
• 3mm heavy-duty DOM seamless shock body
• Precision honed internal bore
• Lightweight machined low-friction piston
• Three-stage FKM-HNBR sealing system
• High-quality natural rubber bearings
• Parker braided high-pressure hoses
• 5140 HV900 hard chrome plated, heat-treated shock shaft
• 6061 aluminium height-adjustable spring seat
• Carbon fibre/PTFE/disulphide low-friction wear band
• CNC TIG welded body end mounts
• EDP surface protection for corrosion resistance
• Direct bolt-on design

Why Three-Way Adjustment Matters

Independent damping adjustment allows the suspension to be tuned for the way your vehicle is actually used.

• High-speed compression helps control sharp impacts from corrugations, potholes, washouts and rough tracks.
• Low-speed compression manages body roll, braking dive, acceleration squat and vehicle stability while carrying heavy loads.
• Rebound adjustment controls how quickly the suspension extends after compression, improving tyre contact and overall vehicle control.

Heavy-Duty Spring Upgrade

The upgraded multi-leaf spring packs are engineered to provide improved load support while maintaining suspension articulation and vehicle control. Combined with the Trackmaster dampers, they deliver a more controlled ride on corrugated roads, gravel tracks and uneven terrain than standard suspension.

Premium Nolathane Bushes

Rather than conventional rubber bushes, the suspension package uses quality Nolathane synthetic bushes designed for improved durability and long service life under heavy loads and harsh operating conditions.

• Nolathane synthetic bushes
• Quality sleeves included
• Designed for long-term durability

Benefits

• Improved ride control on corrugations and rough tracks
• Better vehicle stability when carrying heavy loads
• Reduced body movement over uneven terrain
• Improved suspension control during touring and expedition travel
• Premium rebuildable shock absorbers for long-term serviceability
• Designed specifically for heavy-duty 4x4 light truck applications
• Professionally fitted by AAV4x4

Built for Australian Conditions

The AAV4x4 Trackmaster Suspension Upgrade is designed for owners who regularly travel corrugated outback roads, carry expedition equipment, tow heavy loads or simply want improved control and durability from their Fuso Canter. Developed around real-world Australian touring conditions, it provides a suspension system that delivers confidence, comfort and reliability where standard suspension reaches its limits.
