The Curb Agajanian Performance Group is a NASCAR Busch Series team. It is owned by record executive Mike Curb and racing personality Cary Agajanian. It currently fields the #43 Curb Records Dodge Charger for Kertus Davis. The team also recieves engines from Evernham Motorsports.
Curb Agajanian made its debut in 1998 at the GM Goodwrench Service Plus 200, as the #96 Big A Auto Parts Pontiac Grand Prix driven by Mike Stefanik. Stefanik qualifed 43rd and finished 35th, one lap down. He ran the next race for the team at Las Vegas Motor Speedway, where he finished 32nd. After missing the next four races, Stefanik was released, and Kyle Petty took over at the Coca-Cola 300, where he finished 12th. Brad Loney was the last driver to run with them that season, finishing 36th at Talladega Superspeedway.
In 1999, the team purchased Stegall Motorsports, switched to #43, got sponsorship from Central Tractor, and hired Shane Hall as their driver. Hall had a fourth-place finish at Myrtle Beach Speedway, and finished 24th in points. Rookie Jay Sauter replaced Hall in 2000, nailing eight top-tens and finishing seventeenth in points. He returned in 2001, and grabbed a pole at Kentucky Speedway, and finished ninteenth in points. Ron Hornaday climbed aboard to relieve Sauter in two races during the season
In 2002, the team lost sponsorship and cut back to a limited schedule, running three races late in the season with Hermie Sadler driving. The team continued to run part-time with Sauter's brother Johnny in 2003 with sponsorship from Channellock. They picked up their first win as a team at the Funai 250, and finished 30th in owner's points.
For 2004, the team switched to Dodge and signed Aaron Fike as the driver. Fike ran thirteen races, his best finish a seventeenth at Dover. In 2005, Fike switched between the 43 and Brewco Motorsports, with his younger brother A.J. filling in. A.J. was not able to crack the top 20, and was released at the end of the season. Aaron returned to the ride full-time.
