JR Motorsports has announced its crew chief lineup for the 2026 O’Reilly Auto Parts Series season. The most notable change is Andrew Overstreet moving from the No. 1 car to call the shots for 2024 series champion Justin Allgaier.
Cory Shea has been promoted from the part time No. 9 entry to Sammy Smith’s full-time crew chief. Rodney Childers was announced as the No. 1 crew chief in late September, leading the way for Carson Kvapil and Connor Zilisch.
After winning 11 races as a crew chief in 2025, Mardy Lindley returns to the No. 88 car, which will run Rajah Caruth on a part-time schedule. Phillip Bell will join the team’s No. 9 car, with drivers Shane van Gisbergen and Ross Chastain announced for partial schedules.
