SPRINT CARS

To the finish line with flying colors

KING'S TECHLAB - EXCEED AND EXCEL

TechLab is our starting point for exploring and developing new technologies. It’s where our new products and features are designed, tested and validated.

Our TechLab R&D culture focuses on constant analysis of what can be done to support ever increasing race engine loads, and how to improve bearing durability.

One of those technologies is pMax-Black™.

pMaxBlack™ combines a unique tri-metal structure with advanced surface processes to deliver superior load capacity.

RACING WITH EXTREME LOAD CAPACITY

Sprint cars are very high powered, open wheel race cars designed primarily for racing on short oval dirt and paved tracks. They’re popular world-wide, and reach speeds in excess of 160mph depending on track size. Sprint cars can be either winged or non-winged. They have a very high horsepower to weight ratio, with weights approx. 1400 pounds and power output over 900 horsepower. This is comparable to a F1 car. Sprint cars don’t have transmissions or flywheels. They use an in-or-out gear box and a quick change rear differential to adjust gearing to the track size. Also, they’re not equipped with electric starters, and can only be started by pushing them off.

Due to this direct drive set up, sprint car speeds are a function of engine RPM’s and rear gearing. This produces very high stresses and loads on all engine components, especially engine bearings.

King’s GPC line of coated engine bearings is designed to withstand the grueling on-and-off loading produced by this form of racing where RPM’s are up and down and the loads are very high. King GPC bearings are 30% stronger than any other tri-metal bearings. Thrust bearings in the GPC Sprint Car line utilize a three piece design preventing thrust surface fracturing and thrust bearing failures.
