Jeff got into motorsports at an early age following his father to work on the #27 Shea ISMA Super at the age of 16. By 1998, he followed his dream of working for a cup series team and moved to North Carolina to work for Bessey Motorsports as a mechanic for Geoffrey Bodine’s team. In 2001 he made the move to TN to work with Tony Lambert at Team Bristol with Kevin Grubb. He gained invaluable experience working under Tony, who previously won several races with Mark Martin.
When Team Bristol closed its doors 2003, Jeff went on to work for Brewco Motorsports on the #37 of David Green, where he continued to work as a mechanic and front tire changer. The team placed 2nd in Busch Series Points that year with 4 wins. 2004 brought many changes to the teams including a move for Jeff to the #27 of Johnny Sauter and crew chief Newt Moore. The team had a successful year with multiple top 5 finishes. In 2005, Jeff was promoted to car chief for the #27 Duraflame car of Greg Biffle. After an amazing year working with Newt and Greg, getting his first win as car chief in Phoenix, and getting the first ever Busch Series pole in Mexico with Jorge Goeters, Jeff decided to move home to NH to pursue his own racing dreams.
In 2006, with the support of his sponsor Locke Crane Services, LLC, Jeff acquired a 10 year old supermodified that he completely rebuilt. With the help of his crew chief Richard Witkum, his hard working crew members, and sponsor Locke Crane Services, LLC Jeff managed 5 wins and took home 4th place his first year in competitive racing at Lee Motor Speedway in 2007. In 2008, Jeff won 2 features before an unfortunate accident sent him over the wall at Lee, completely totaling his car.
2009 was Jeff’s first year in the ISMA Supermodified Series. As an unkown to those who weren’t aware of his past career manning the wrenches on cars in the Busch Series,Locke surprised many when he began showing up at ISMA shows with a new Brian Allegresso build No. 37 big block. Surprise turned to shock when Jeff held off seven-time ISMA champ Russ Wood to win a feature at Ontario’s Delaware Speedway in only his sixth ISMA start.
Jeff and his crew had a lot of success in the ISMA series. Jeff won two features, one at Sunset Speedway and one at Delaware Speedway. He finished top 10 in points for the year 3 times and top 5 in points for the year 3 times.
In 2017 Jeff made the decision to retire from racing and focus his efforts on Ryan and Chase.
