4LT GS Roadster
HAMPTON, Ga. – A $250 part can be worth millions in misery and aggravation.
That’s roughly the cost of a rear axle used in Sprint Cup cars, the kind every team purchases and builds into machines worth hundreds of thousands and that represent sponsorships worth millions.
One of those $250 axles went bad on Dale Earnhardt Jr.’s No. 88 Chevrolet at Fontana, CA, a few weeks ago, knocking him out of the race and sending a wave of anxiety through Hendrick Motorsports engineers, who had built identical parts into the team’s other three cars. Jimmie Johnson’s rear axle showed extreme wear, team officials said, but survived long enough to take him to Victory Lane.
