U-Bolts
Our U-Bolt division manufactures square, semi-round, and round U-Bolts from 1/2″ diameter bar up to 1-1/2″ diameter. Remember to never re-use U-Bolts. Used U-Bolts have been stretched while under torque, which is what they are designed to do, and will not hold the proper torque if re-used. Instead, re-torque U-Bolts after 500 miles or replace with new U-Bolts.
We can help you find the right U-Bolt for your needs. We have a good selection in stock and ready to order.
