RACING has developed a drive system that takes all the worry out of driving essential engine components and the fear of power steering belts coming off and the old problem of standard oil pump failure causing super-expensive engine repair bills.

This picture shows our set of ROSS RACING HTD toothed pulleys mounted to a common drive on the front of the Harmonic balancer. The belt is retained using a taper sided washer on the front of the drive.

Both the external oil pump and the power steering pump are running at ½ engine speed, this is especially helpful in the prevention of the belts flying off the engine.

By the way this is the same drive ratio as the cam shafts.

Also shown in the picture is our Crank trigger and CAS replacement Housing for use with the kit when using our hall sensors.

This is a 2000 hp Harmonic balancer we have for use on serious race engines.

Our bonded Balancers never need rebuilding or pulling apart for a service. So with regard to the rubber side of things they are held together and dampened with a high quality, high tensile natural rubber.

The rest of the balancer is made from 2 materials, the hubs are made from a 40 tonne tensile carbon steel for turbo or N/A engines, we have an option for blown applications, this can be either 4340 steel, or Titanium.

The next feature is for accessory mounting. The front of all our balancers are also drilled with 6 x M8 which take a direct fit of one of our external oil pump drives or fuel pump drives . In some cases 6 x 3/8” UNF threads and either an external or internal spigot for location of other pullies . This 1UZFE  balancer has both allowing a 2 inch adaptor to drive a roots or PSI blower.

Ross Performance Parts Produces a number of Harmonic Balancers

Heavy Duty Harmonic Balancers

ROSS TUFFBOND HEAVY DUTY reconditioned harmonic balancers / crank pulley dampers are manufactured using traditional dampening materials and assembly methods are prone to breakdown through heat and vibration. The twisting forces applied to the harmonic balancers / damper particularly in performance applications causes spinning and loss of timing accuracy.

The unique TUFFBOND process used on every ROSS harmonic balancers /crank damper eliminates these common problems by creating an intermolecular bond between the special formula dampening rubber and the metal housing.

All Harmonic Balancers/ Dampners now SFI Compliant.

Street Performance Harmonic Balancers

ROSS TUFFBOND Street Performer Series Reconditioned Harmonic Balancers / Crank Pulley Dampers are manufactured for over 100 engine types and offer excellent upgrade in reliability and dampening performance for standard or street performance engines.
All Street Performer Series Harmonic Balancers / Crank Pulley Dampers are unconditionally guaranteed against failure for unlimited kilometres up to 12 months from purchase. Street Performer Series Harmonic Balancers / Crank Pulley Dampers sare sold on the exchange basis with deposit charged until core return.

NEXUS Series Harmonic Balancers

NEXUS! The exciting new range of harmonic balancers within the ROSS TUFFBOND group aimed at satisfying the needs of those who realise and appreciate the enduring reliability of ROSS TUFFBOND Harmonic Balancers / Crank Pulley Dampers but don’t need all of the refinements of the MetalJacket Harmonic balancer range.
NEXUS Harmonic Balancers / Crank Pulley Dampers 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.

METAL JACKET Harmonic Balancers

Introducing a revolutionary development in torsional dampening technology. Utilising the ROSS Tuffbond original elastrometric bonding process to produce the ROSS Metaljacket® series harmonic balancers / crank pulley dampers.Metaljacket Harmonic Balancers/Crank Dampers designed and manufactured by ROSS.
Metaljacket use the highest spec. 6000 series alloys along with aerospace 7075 hard anodised crankshaft hubs.
Metaljacket is designed to be used on race machines that are driven by enthusiasts on the street, strip,circuit or on the water.
The accessary drive pulley ratios are standard unless requested.

MJ RACE Harmonic Balancers

MJRace balancers/dampers are made from the highest grades of materials that don’t break.

For Naturally aspirated and turbo engines the crank hubs are made from 7075 aerospace alloy.

But in the case of supercharged engines 4340 alloy steel is used for the crank hubs.

The accessory drive pulley ratios are mostly between 10% and 25% underdrive.

This prevents engine overheating , alternator and power steering failures due to overspeed.These harmonic balancers / crank pulley dampers are made to suit ANDRA requirements and meets sfi rules If your engine regularly sees RPM between 10% and 20% more than standard and you are racing on the track doing multi lap events, using fuel cuts and rev limiters in the programming of your engine, as well as rapid accelleration and decelleration then you will need a race series balancer / damper.

You might be wary of hanging a heavy hunk of metal on the front of your crankshaft, but a quality racing crank damper will actually produce horsepower and help your engine live longer.

What Does A Crank Damper do?

Crank dampers absorb (damp) the torsional vibration of the crankshaft to prevent the failure of the crankshaft by fatigue.

Crank dampers improve the Noise, Vibration, and Harshness (NVH) charartristics of the vehicle prodiving an overall enhanced driving experience.

Why Do your Need A Crank Damper?

A harmonic balancer (also called crank pulley damper, crank damper, crankshaft damper, torsional damper, or vibration damper) is a device connected to the crankshaft of an engine to reduce torsional vibration and serves as a pulley for drive belts.

Every time the cylinders fire, torque is imparted to the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torques imparted by the cylinders are in synch with the vibrations in the crankshaft, which results in a phenomenon called resonance. This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure. A crank damper helps to prevent this

To prevent this vibration, a Crank Damper is attached to the front part of the crankshaft. The crank damper is composed of two elements: a mass and an energy dissipating element. The mass resists the acceleration of the vibration and the energy dissipating (rubber/clutch/fluid) element absorbs the vibrations.

Additionally the energy transferred from the piston to the crankshaft can induce as much as 2 degrees of twist in the crankshaft, which has many follow-on effects on all engine elements that require adequate timing such as valve opening, cam timing, ignition timing etc.

Over time, the energy dissipating (rubber/clutch/fluid) element can deteriorate from age, heat, cold, or exposure to oil or chemicals. Unless rebuilt or replaced, this can cause the crankshaft to develop cracks, resulting in crankshaft failure.

New cam sensor kit for RB Nissan engine. Using a Hall effect sensor Ross has created a revolutionary cam sensor kit for RB Nissan engine package a with a single cutout trigger. This will allow for more positive mapping when used along with the already successful crank angle sensor and trigger wheel kit.

The completed kits will be anodised black with engraved 1 degree intervals around the adjustment slots for easy adjustment recording. The single cutout trigger mounts to the face of the cam and locates into the dowel hole in the cam pulley. The trigger has been accurately balanced to prevent any out of balance that may cause cam bearing problems.

“At ROSS we think of everything”.

This is a Fiat F600 balancer. From std theses engines had an oil pump incorporated in the front of a cast iron pulley hub.

We have redesigned the original part to suit one of our MetalJacket S.F.I. Dampers consisting of a 1045 steel hub, 6061 alloy dampening hub and Steel dampening cover held together with our tried and proven TUFFBOND process. In their std trim these engines were harsh as they had no dampening at all.
