NEXUS! The exciting range of Harmonic Balancers
ROSS BALANCERS, WE TELL YOU WHAT OUR PRODUCT IS MADE FROM, THE CHAMPIONS WHO USE OUR PRODUCT TELL YOU HOW GOOD IT IS.
NEXUS! The exciting range of Harmonic Balancers in the ROSS brand aimed at satisfying the needs of those who realise and appreciate the enduring reliability of ROSS Harmonic Balancers but don’t need all of the refinements of the MetalJacket Harmonic Balancer range.
NEXUS Harmonic Balancers are machined on our own CNC machines in Australia, from 1045 grade carbon steel and bonded using the super reliable TUFFBOND molecular bonding process developed by ROSS and used continuously since 1981.
The NEXUS Harmonic Balancers range are all balanced in our factory and are made to exceed A.N.D.R.A. requirements for drag racing in AUSTRALIA.
Each NEXUS Harmonic Balancers is chemically treated to provide a long rust free life in service and after treatment they are Laser engraved with Logo, part number and radially engraved timing marks.
Race series have been designed to suit the extreme conditions and harshest racing environments in the world. They are used in the middle east in 4wd drag racing 1/8 mile in the sand, to blown alcohol race boats and even Hillman Imps running in Historical series around the tracks of Australia.
This balancer is made from high tensile carbon steel and Billet aluminium and bonded together with the trusted Tuffbond process. We have catalogued these products from all the special needs of racers across Australia. Mostly now they carry the 360 degree timing marks and anodised aluminum pulleys. Mostly they will not suit all the factory accessories as they are designed for racing.
Metaljacket is a world class uniquely designed product made completely in Australia and fit all the O.E.M. pulleys.
The aluminium Metaljackets of the products are anodised and laser engraved for accuracy a full 360 degrees for engine set up. This means no more degree wheel.
The only components from outside Australia are the raw materials. This balancer is made from high tensile carbon steel and Billet aluminum and bonded together with the trusted Tuffbond process as well, Metaljacket has a unique “dead cushioning” dampening feature where the Metaljacket has dampening between the safety cell and the outer dampening ring of the balancer.
The Balancer is designed so as the Metaljacket retains the outer ring of the balancer. All of these race and street balancers meet A.N.D.R.A. and SFI specs.
