Lowell is approximately 26 minutes from our Stoneham shop on Pine Street. We see customers from Lowell, Chelmsford, Tewksbury, Dracut, Tyngsborough, and the wider Middlesex County area every week. Most Lowell driving runs through Gorham Street, Bridge Street, and the Lowell Connector to I-495, which shapes the wear pattern on the vehicles we service.

Lowell is dense urban with rough streets. We replace more sway-bar end links and lower control-arm bushings on Lowell vehicles than on any other city in our area.
