U-Bolt Services
Bud's Spring delivers precision U-bolt fabrication, replacement, and torque services for heavy-duty truck and trailer suspensions. We supply and install premium U-bolts from trusted manufacturers including Dayton Parts, Hendrickson, Meritor, and Ridewell, guaranteeing secure axle-to-spring attachment, vibration-free performance, and maximum safety under heavy loads.
Our U-Bolt Services Include:
- Custom U-bolt fabrication – bent to exact specifications (round, square, semi-round) using high-strength Grade 8 or 10 rod stock
- U-bolt replacement kits – complete with nuts, hardened washers, and lock washers from Dayton Parts and Meritor
- Thread repair and chasing – restoring damaged or stripped threads for perfect fit and torque retention
- Precision torque verification – using calibrated tools to meet OEM and TMC recommended practices
- Re-bending and straightening – correcting deformed U-bolts or fabricating replacements on-site
- Corrosion-resistant coatings – hot-dip galvanizing, zinc plating, or powder coating for severe-duty applications
- Inspection and measurement – checking for stretch, cracks, or wear with digital calipers and dye penetrant testing
- Integration with suspension overhauls – paired with leaf spring, axle, or trunnion services for complete repairs
- Bulk and fleet orders – fast production of matched sets for multiple vehicles
Our in-house bending machines, threaders, and extensive rod stock inventory allow same-day service on most U-bolt jobs. All work follows SAE J429 strength standards and includes final torque checks before release.
