Veteran-owned & family-operated since 2010 — West Chester, PA
STR stands for what we do best: Steering, Transmission, and Rears. Founded in 2010 by a veteran with a passion for heavy-duty trucks, STR Rebuilders has grown from a small specialty shop into a trusted name for drivetrain rebuilding across Pennsylvania, New Jersey, Delaware, and Maryland.
We're a family-operated business with over 60 years of combined experience in the trade. Our team has rebuilt drivetrains for everything from fire trucks and municipal vehicles to construction equipment and over-the-road tractor trailers. If it has a transmission, a rear end, or a steering box — we rebuild it.
Every rebuild leaves our shop with a 2-year, unlimited-mile warranty because we stand behind the quality of our work. We use OEM and premium aftermarket parts, and we believe in honest pricing with no hidden fees. Your truck is your livelihood — we treat it that way.
Sheppard, TRW, and Ross steering gears rebuilt to OEM specs for all heavy-duty applications.
