Steering Coupler 911/912
The last Steering Coupler your 911/912 will ever need; completely and totally fail-safe, fits early and late applications without any modification at all.
For reasons understandable when our cars were new, the factory bought steering gear couplers of elastomeric ‘discs’ or ‘tubes’ with bonded metal fastening inserts.
The metal parts tended to last forever while the elastomers failed, with the possibility of leaving scant or no connection between the steering wheel and the front wheels. It is axiomatic that any elastic elements, even those reinforced with cord (like 20-year-old tires), and even the parts in our Precision Matters product, fail long before any metal does.
When the cars were new(er), the factory properly assumed the cars got inspections on a regular basis and any deterioration would be noted and corrected at that time. Most of our cars no longer get those regular inspections. Precision Matters’ Steering Coupler means irregular inspections won’t have you sawing wildly at the wheel under any circumstances.
The Precision Matters design maintains the desired compliance by passing the steering inputs and reactions through elastic elements. But instead of capturing metal inserts in an elastic disc, ours safely encapsulate the elastic elements; radially, between two aluminum discs and axially, by metallic fasteners (See “Schematic” on Details page).
As a result, steering wheel/linkage connection is guaranteed under complete failure of the elastomers. Under that complete failure, the steering wheel would gain ~1″ radial ‘slack’ at the rim and ~.03″ axial movement. You would remain entirely in control of your car. And when they fail, sometimes in the future, you can buy replacement inserts at a local bearing dealer; they are “square O-rings”.
