New hybrid OME nitrocharger sport shocks

Are these in the States yet? They sound like a big improvement over an already great shock, but are around $50(AU) more per corner. I find it amusing how they refer to the term R&D(and we get charged accordingly) when "camping in the Outback for a few weeks" is probably more accurate. I know its more involved than what I let on, but who wouldn't want to do a this type of R&D?

Old Man Emu has been at the forefront of suspension innovation and design since 1979, and now we are thrilled to announce the release of Nitrocharger Sport, the most finely tuned 4×4 shock absorber Australia has ever seen.

Despite its namesake, Nitrocharger Sport does not rely solely on knowledge gained from OME’s trusted Nitrocharger shock absorbers. Instead, a team of OME ride control engineers launched an exhaustive vehicle specific development program –
involving new valving techniques and components, scientific data logging, and comprehensive field testing – to ensure Nitrocharger Sport delivers even greater control, durability and a comfortable ride over all terrain.

Nitrocharger Sport’s fine tuning is directly related to the three individual tuning points within the shock absorber, which incorporate a total of twenty-six deflective discs. Each disc can be altered in thickness and diameter, offering almost infinite tuning options. In real driving terms, this translates to precise tuning truly matched to specific vehicles and their requirements.

“The process was incredibly involved,” says Stuart Fooks, one of the OME ride control engineers behind the development project. “We would fit the shocks onto a vehicle, say the 100 Series, and find that while they may show a marked improvement in corrugations, highway travel might feel somewhat hard or cause the vehicle to wallow. So we’d take the shocks back into the lab and run simulations on how each shock would react after the replacement of a disc with perhaps a thicker or smaller one. Once we were satisfied with the data, we’d implement it on the real shock absorbers and head out for field testing once again.”

One vehicle alone required 64 different valving configurations before the ride control engineers were satisfied with the improvements in ride, handling, and control of heavy loads.

The discs themselves are separated into three individual stacks. The compression stack located in the base of the shock absorber noticeably softens impacts with road imperfections for a less harsh, more rounded feel, while the new high flow piston incorporates both a rebound and a compression stack. The piston compression stack ensures there is no lag in the valving response time when uneven terrain is encountered, giving a refined, comfortable and well controlled ride. Meanwhile, the piston rebound stack allows initial control over small road imperfections and a heavier and more commanding control when demanding conditions are encountered.

Combined, these three stacks offer the most cohesive, balanced and finely tuned valving system on the market, translating into a smooth ride and optimum control uniquely tailored to both on road driving and off road touring.

“We wanted a shock absorber engineered for all driving situations,” Fooks says. “The multi disc stack tuning allows this.”

To complement the new valving system, a new high flow piston has been engineered with a less restrictive design and open apertures to ensure a more uniform oil flow through the disc stacks, reducing heat generation and oil aeration which can lead to shock absorber fade. The oil itself is a petroleum based, high performance formula designed to resist fade and aeration, further extending shock absorber durability and performance in harsh conditions.

A large rod guide incorporates a new triple lip oil seal capable of handling greater internal pressures and higher temperatures for long lasting durability. The seal also features a new gas retention check valve design to virtually eliminate contaminant damage and provide outstanding gas and oil retention. And to ensure a consistent and uniform performance across the shock absorber range, a Teflon infused bronze slip ring has also been incorporated into the new rod guide to guarantee tight manufacturing tolerances are maintained.

The 1.6mm heavy gauge steel reserve tube protects internal components from stone damage, and has been further enhanced with an impact resistant polyethylene dirt shield for additional protection.

Final testing of Nitrocharger Sport took place in real Outback conditions beyond Broken Hill, NSW, and involved multiple vehicles, multiple suspension system designs, and a complex Motec data acquisition system to accurately and impartially assess the shock absorber’s capabilities in differing terrain. After three years of engineering and development, the results reveal that Nitrocharger Sport delivers better control, more comfort, and faster reaction times than both our trusted Nitrocharger shock absorbers and competitor brands. The extensive travel across extreme corrugations further revealed that Nitrocharger Sport has outstanding resistance to high operating temperatures that is superior to both Nitrocharger and our competitors. And most importantly, Nitrocharger Sport’s precision tuning means that these benefits are individually tailored to your vehicle and are immediately felt across all road surfaces.

The team at ARB is very excited about the new shock absorber. OME Product Manager Syd Groves states, “Nitrocharger Sport raises the bar in 4×4 shock absorbers, with performance and durability that other brands will not be able to match. And despite all this, the price is extremely competitive – our customers will be thrilled.”

Nitrocharger Sport comes with a three year, 60,000km warranty, and is available now for a range of 4WDs. Contact ARB for details on the latest OME suspension options for your vehicle.

IMO, not worth the money. I've actually never been impressed with the OME shocks. When you break it down, it's really just a twin tube shock with an elevated price.

Sounds like they have finally embraced deflective disc valving. That 3rd stack is intriguing. Seems like there are more cost effective ways to do low speed damping (I'm assuming that is it's purpose), but at least they're moving forwards in product design.
