What is Stiff Ring?

Stiff Ring is simple in their shape and clever in their design. The material from which they are made is of a special formula aluminum which is commonly used in aircraft frame building.

The basic principle is one of chassis strengthening and rigidity without going overboard and compromising the cars inherent handling characteristics.

The Stiff Ring kit is simple to fit and low cost and it eases into position without affecting the basic geometry of the body.

Bolt holes through the chassis panel and sub frame are normally too big as they were designed for ease of production in the factory. 

When the car leaves the factory, everything is new and tight and the chassis hardly moves. After a while, the bolts become slightly looser and movement between the panels begins.

This is why an older vehicle fitted with new bushes, Shocks and springs, still doesn't behave like a new car. The car engine, transmission, suspension and the body shelf are mounted on the sub frame.

The Stiff Ring is an aluminum washer with a square outside Taper to increase adhesion on the Thinner flange portion in the middle. This fits between the moving panels and with a properly sized bolt (and Bolt Hole as part of the Stiff Ring) is crushed into place when tightened, joining the two panels and stopping movement forever.

Stiff Ring cures chassis movement, improve handling, reduce road noise, reduce vibration, improve braking and make the car safer in an accident.

With the Stiff Ring in proper place, the gap is filled up to stop the movement of the sub frame and the car body forever and provide ideal alignment between both, as a result of a perfect geometry setup.

Stiff Ring is also customizable for any car with a very affordable price, which makes the selection endless to whoever make of car on the road today.
