MONROE DEVELOPS SUSPENSION FOR NISSAN NAVARA N-TREK WARRIOR

The first units were delivered to customers in December

DRiV owned Monroe Shock Absorbers and Monroe Springs are reportedly integrally involved in an Australian engineered Nissan Navara 4WD model variant – the Nissan Navara N-TREK Warrior – which was launched in October of 2019.
Premcar is the Melbourne-based vehicle engineering company enlisted by Nissan to develop and manufacture the Navara N-TREK Warrior to OEM standards and this specially enhanced Navara model is being assembled at the company’s new 6,300 square-metre production facility located in Epping (Victoria).
Monroe Australia says its ride performance product engineers worked together with Premcar to locally design, develop and rigorously test this significantly enhanced suspension system.
Combined with several Warrior model exclusive additions, Nissan now has a formidable competitor in the lucrative Dual-Cab 4WD market, which accounts for 60 percent of all Utes sold in this country.
The Monroe Australia engineering team developed a new suspension set-up for this top of the range Nissan Navara with dual-rate springs and upgraded premium Rancho dampers that have been designed to improve handling, ride comfort, stability, steering response and ground clearance.
The Nissan Navara N-TREK Warrior is equipped with unique 17-inch wheels, (which are smaller than the N-TREK’s standard 18-inch wheels) to accommodate larger 32.2-inch 275/70 Cooper All Terrain Tyres.
These increase the ride height by 25mm and combined with a 15mm lift from the new springs and dampers, ground clearance has been increased by a total of 40mm (to 268mm).

‘Track’ has also been boosted to 1600mm across both the front and rear, giving the new Nissan Navara N-Trek Warrior an instantly visible taller, wider and tougher stance.
The Navara’s standard dampers were replaced by Monroe Australia’s specially developed Rancho 4WD shock absorbers which feature a larger outer tube diameter containing greater oil volume for better cooling and rough-road capability.
These locally developed 4WD shock absorbers include a thicker piston rod for increased strength, as can be found in all Monroe TDT Gas Magnum 4×4 and Rancho 4WD replacement shock absorbers, but with the added feature of a Premcar specified internal valve code to match the springs and tyres, including more compression damping for quicker response.
Jointly the Monroe Springs engineers worked closely with Premcar to design, develop and manufacture the front and rear coil springs to achieve the desired, fine-tuned ride performance for Nissan.
Building on the experience of over 90 years of designing and manufacturing springs in Australia to OE standards with expertise in both on and off road segments, namely with Rancho, Monroe says its springs were integral to meeting the project’s demanding timing and OEM quality standards.
Monroe says the end result was a softer primary spring rate to improve ride comfort and off-road articulation, coupled with a higher but more progressive secondary rate. This was done to maintain composure and performance for cornering, heavy duty off-roading and for towing.
The upgraded suspension set-up also reportedly improves the Navara’s off-road ability without reducing comfort, safety or its 3,500 kilogram towing capacity. The detailed suspension modifications also improve the vehicle’s approach, departure and rampover angles.

Development testing of this locally engineered Nissan Navara model took place on varied road surfaces at the Australian Automotive Research Centre (AARC) and on sandy tracks, gravel roads and rough Mallee terrain between Ouyen in Victoria and Pinnaroo on the South Australian border across several months.
The work that Monroe Australia and Premcar have done to enhance and develop this new model’s exclusive suspension has already gained wide acclaim from the Australian motoring media.
“The high riding Monroe developed suspension has big-bore shock absorbers and taller
springs, delivering an extra 40mm of ground clearance and an unmistakably tough stance,” News.com.au reported.
“A longer free-standing spring height achieves the required lift and is a much better way to go for an off-roading 4WD. You don’t want stiff springs as this ain’t no bitumen-bound race car. These are matched up by new dampers made by the same OEM supplier (Monroe),” reported CarAdvice.
“Revised spring rates and damper setting were developed with Adelaide-based Monroe to provide an improved progressive rate performance, raising the ability of the suspension to conform to the ground surface and not be subject to bounce, reducing the tyre contact patch pressure and thereby maintaining higher levels of control,” said Delivery Magazine.
“At the rear, the already (twice, over the years) stiffened up standard Navara coils have come in for their third harden-up session for the Warrior with the Navara’s OE suspension supplier Monroe tasking its Australian engineers with a solution that would improve both on and off-road manners. Nissan pulled up short of specifying the high-end, racing-derived by-pass dampers for the Warrior, but did ask Monroe for something matched to the new coils,” said Unsealed 4X4 / Pat Callinhan’s 4X4 Adventures.

“There is a bespoke spring and damper package, built locally by Monroe. The spring rates are reduced on both axles, both for greater wheel articulation off-road and more balanced handling on-road,” Chasingcars.com.au noted.
According to DRiV South East Asia Pacific Marketing Manager, Brydon Tweddell, this is an outstanding example of the skill and expertise of the Monroe Australia shock absorber and Monroe Springs engineering and manufacturing teams.
“Our engineers worked closely with Premcar to develop a 4WD suspension solution that is unrivalled in the Dual-Cab 4WD market in this country,” Brydon said.
“We are very proud to bring our Australian-based engineering and manufacturing expertise to the exciting new Nissan Navara N-TREK Warrior and look forward to the opportunity to contribute to other local development opportunities that come in the future.
“The market has shifted considerably in the last two years with Ute sales leading the way, but Ute buyers are looking for a higher grade with more features that make their vehicle stand out,” Nissan Australia Managing Director, Stephen Lester, said at the launch of this exciting new addition to Nissan’s Ute range.
“The Nissan Navara N-TREK Warrior is locally designed and engineered for Australian conditions and we expect this to be a strong addition to the Navara line-up.”
