Harvick keeps championship crew chief Childers in the fold with extension at Stewart-Haas

Stewart-Haas Racing has signed the crew chief for reigning NASCAR champion Kevin Harvick to a multi-year contract extension.

Rodney Childers helped lead Harvick to five wins and eight poles during the 2014 championship season. He was rewarded Friday with a deal that will maintain the successful pairing for a few more seasons. Exact terms were not disclosed.

Harvick and Childers lead the points standings this season, with two wins and 12 top-10 finishes. They've led 1,123 laps this season heading into Sunday's race at Pocono Raceway.

SHR co-owner Tony Stewart says keeping Harvick and Childers together was a "high priority" because of the high standard of excellence they have set in the No. 4 Chevrolet.
