Gold Performance

The KING High Performance Problem Solvers

Meet Gold Performance, newest member of KING’S performance problem solvers. Load capacity is nearly double that of today’s performance bearings. Temperature threshold is over 50% higher than other trimetal bearings. 18,000 psi and 540°F open many possibilities…hey, the developmental playground just got a new toy.

So it’s time to make more power; time to try things you couldn’t try before.

Gold Performance is ready for all challenges and your imagination.

Gold Performance will put your engines up front and your name above the rest. It will

give you the winning edge and the get-go to tweak it ‘til it howls.

Load equals power. Too much kills bearings; not enough loses races.

Our three performance brands are all about power. From huge power that lasts for seconds, to high power that lasts for hours, KING has a race bearing that best suits your needs.

At KING, all we make is bearings; five decades of continuous investment, improvement, growth,

Don’t just take our word for it.

Xtreme Performance Problem:

• Your current OE or performance bearing is flaking or “chunking out” (trimetal/bimetal fatigue failure).

Causes:

• Engine load exceeds your bearing’s fatigue point.

Solution:

• Select KING Xtreme Performance bearings.

• The .0005” high performance overlay and trimetal construction offer 15% – 30% greater load capacity than conventional OE or bimetal bearings.

• Xtreme Performance bearings feature Securebond, KING’S enhanced adhesion process.

• This special surface preparation and heat treatment ensures superior adhesion between nickel dam and intermediate layer.

Problem #1:

• Your current trimetal bearing’s Babbitt overlay extrudes over the sides, migrates to one end, or gets physically removed by the crankshaft. The intermediate layer is exposed, damaging the crank journal, requiring expensive grinding or replacement.

Causes:

• Engine load and/or temperature exceed the limits of your bearing.

• Excessive engine load overcomes the hydrodynamic lubrication principle, allowing metal-to-metal contact between crank journal and bearing.

Problem #2:

• Contaminants entered the oil stream, scratching and damaging the crankshaft journals.

Causes:

• Difficult to eliminate residual machining particles from last rebuild.

Solutions:

• Select KING Pro Series bimetal HP bearings.

• The .015” thick top layer can be squeezed and worn up to .010” (vs trimetal .0005”) without damaging the crank journals.

• Its Vickers hardness of 40 withstands momentary high loads better than softer Babbitt’s Vickers hardness of 15-20.

• The thick top layer provides better macro-particle (>.00025”) embedability vs trimetal HP Babbitt (.015” thickness vs .0005”).

• Pro Series temperature threshold is almost 30% greater than trimetal (450ºF vs 350ºF).

Problem:

• Your bearings look like this:

Causes:

• Engine load exceeds your bearing’s fatigue point.

• Temperature exceeds your bearing’s temperature threshold.

Solution:

• Select KING Gold Performance bearings.

• The proprietary overlay withstands almost twice the load of other performance bearings (18,000 psi vs 10,000 psi).

• The temperature threshold is 50% greater than others (540ºF vs 350ºF).

“We tested KING Gold Performance against a competitor’s best performance bearings for a week on our dyno, in one of our 410 sprint car engines. These were punishing tests for 8 hours a day beginning with constant loads of 300 ft lbs to over 500 ft lbs – well beyond most race conditions.

After the first day, the other bearings already showed initial overlay fatigue while the Gold shells were perfect. From there we tested Gold – narrowed by 40% – against full width competitor shells. Every 2 hours we had to replace the competitor shells due to fatigue – but the same Gold bearings, narrowed by 40%, kept right on running to over 500 ft lbs constant load.

KING Gold is the new benchmark for me.”

For all performance applications using forged steel aftermarket crankshafts and producing high loads for extended periods.

Such applications include circle track, off-road and off-shore racing.

For those applications in which traditional high-performance trimetal bearings undergo overlay fatigue and failure due to extreme loading for extended periods of time.
