Description

Nissan Navara NP300 Pedders Super Heavy Duty Load Carrying & Towing Complete Front & Rear Suspension Kit – 300kg Constant Load

Upgrade your pickup with the complete Nissan Navara NP300 Pedders Super Heavy Duty Load Carrying & Towing Suspension Kit.

Designed for the Nissan Navara D23, also known as the NP300, this complete front and rear suspension package combines fully assembled Pedders TrakRyder Ezi-Fit front struts with a Super Heavy Duty constant-load rear suspension setup.

This kit is specifically designed for permanently laden vehicles carrying a minimum constant rear load of 300kg at all times.

It is suitable for heavily equipped commercial vehicles, overland builds, touring pickups and working Navaras carrying substantial permanent accessories or equipment.

Complete Front and Rear Suspension Upgrade

This Pedders package provides a matched suspension upgrade for the front and rear of the Nissan Navara NP300.

The front suspension is supplied as two fully assembled TrakRyder Ezi-Fit struts. Each assembly combines a foam-cell shock absorber, matched raised coil spring and upper strut mount.

The rear suspension uses Super Heavy Duty constant-load springs designed to support a permanent load of at least 300kg.

Together, the components help improve ride height, load support, suspension control and vehicle stability when the Navara is carrying substantial permanent weight.

Kit Includes

• Two fully assembled Pedders TrakRyder Ezi-Fit front struts
• TrakRyder foam-cell front shock absorbers
• Matched raised front coil springs
• New upper front strut mounts
• Pedders Super Heavy Duty rear suspension components
• Constant-load rear springs
• Rear suspension setup for a minimum permanent 300kg load
• Raised front and rear suspension configuration
• Vehicle-specific components for the Nissan Navara D23 NP300

Exact package contents may vary according to the vehicle year, model and selected suspension application. Please confirm the final kit specification before ordering.

Fully Assembled Pedders TrakRyder Ezi-Fit Front Struts

The front suspension includes two complete Pedders TrakRyder Ezi-Fit Spring and Shock assemblies.

These units are designed to provide precise suspension control while maintaining suitable ride comfort for a heavily equipped vehicle.

Each front strut is supplied fully assembled with:

• Pedders TrakRyder foam-cell shock absorber
• Matched raised coil spring
• New upper strut mount
• Vehicle-specific mounting components

The complete assembly removes the need to dismantle the original struts or transfer old springs and top mounts.

It also eliminates the need to assemble the new front struts using a spring compressor, reducing installation time and ensuring the main components are correctly matched.

Direct-Fit Front Suspension

The Pedders Ezi-Fit front struts are supplied ready for direct installation.

Benefits include:

• Faster installation
• No front strut assembly required
• No need to reuse worn original top mounts
• No spring compressor required during assembly
• Matched springs and shock absorbers
• Consistent suspension performance
• Ready for professional installation

Pedders Foam-Cell Shock Absorber Technology

The TrakRyder front struts use Pedders foam-cell shock absorber technology to deliver controlled and dependable damping.

The large internal oil capacity and increased cooling area help manage temperatures during demanding use.

The foam-cell construction also helps reduce the mixing of air and oil inside the shock absorber. This supports consistent damping during towing, heavy load carrying, rough-road driving and repeated off-road suspension movement.

The front assemblies are designed for demanding conditions ranging from daily road use to severe off-road tracks.

Pedders Super Heavy Duty Load Carrying & Towing Rear Suspension

The rear of this kit uses the Pedders Super Heavy Duty Load Carrying & Towing Suspension Kit specification.

This rear suspension is specifically designed for Nissan Navara NP300 vehicles carrying a substantial permanent load.

A constant minimum load of 300kg must remain in the vehicle at all times for the suspension to operate within its intended application.

The additional weight may come from permanently fitted equipment, accessories or commercial load carried over the rear axle.

Minimum 300kg Constant Load Requirement

This is not a general-purpose heavy-duty suspension kit for vehicles that regularly travel empty.

The Super Heavy Duty rear springs are engineered around a permanently laden vehicle. They require at least 300kg of constant additional weight to achieve the intended ride height, suspension movement and ride characteristics.

Suitable permanent equipment may include:

• Heavy commercial canopy
• Permanently fitted drawer systems
• Tool storage and workshop equipment
• Recovery equipment
• Auxiliary fuel tanks
• Water tanks
• Overland equipment
• Camping systems
• Heavy roof or tub-mounted accessories
• Permanently carried commercial equipment

The permanent load should be accurately calculated before ordering.

DNA4x4 can help assess the accessories and equipment fitted to your Navara to determine whether this Super Heavy Duty specification is suitable.

Important Unladen Ride Warning

This suspension kit is not recommended for vehicles that are normally operated empty.

Without the required minimum 300kg constant load, the rear suspension will be very firm.

An unladen vehicle may also sit higher than intended and provide reduced suspension compliance over bumps and uneven surfaces.

Customers should select this kit only when the vehicle will remain permanently loaded with at least 300kg.

For Navaras that regularly travel unladen or carry only moderate weight, a lighter progressive or heavy-duty suspension option will usually be more appropriate.

Designed for Permanently Laden Vehicles

This Super Heavy Duty suspension package is suitable for vehicles used for:

• Permanent commercial load carrying
• Heavy canopy installations
• Fully equipped overland builds
• Permanently loaded touring vehicles
• Mobile workshop conversions
• Utility and service vehicles
• Heavy tool storage
• Regular towing with substantial permanent equipment
• Vehicles carrying at least 300kg at all times
• Demanding road and off-road applications

Improved Load Support

Standard suspension can sag when substantial permanent weight is added to the rear of the vehicle.

This can reduce ground clearance, suspension travel and vehicle stability.

The Pedders Super Heavy Duty rear suspension is designed to provide increased support for permanently laden vehicles, helping reduce:

• Excessive rear suspension sag
• Loss of ride height
• Reduced suspension travel
• Excessive body movement
• Poor stability
• Uncontrolled pitching
• A wallowing or unsettled ride
• Poor control over uneven roads

Towing Performance

The additional rear suspension support can help improve control when towing a trailer or caravan.

It may help the Navara remain more stable when permanent accessories and towing loads place additional pressure on the rear suspension.

The suspension kit does not increase the vehicle manufacturer’s legal towing capacity, payload, axle ratings or gross vehicle weight.

All loads must remain within the original manufacturer limits.

Raised Suspension Height

The raised suspension setup can increase front and rear ride height while helping restore height lost through permanent accessory weight.

The final height increase will depend on:

• Permanent load
• Load position
• Vehicle specification
• Engine configuration
• Existing suspension condition
• Fuel level
• Accessories
• Selected spring specification

The Super Heavy Duty springs must be fitted to a correctly loaded vehicle to achieve the intended ride height and suspension performance.

Improved Ride and Handling Under Load

When correctly matched to a permanently laden vehicle, this Pedders suspension kit can help improve:

• Load support
• Ride-height consistency
• Body control
• Steering response
• Braking stability
• Suspension recovery over bumps
• Towing stability
• Rough-road control
• Ground clearance
• Overall driving confidence

The suspension is designed to perform with substantial permanent weight. It is not intended to provide a soft ride when the vehicle is empty.
