This guide is for trailer owners and mechanics who need secure fastening for single parabolic leaf springs, offering a high-tensile solution for critical load-bearing areas. The key benefit is enhanced safety and durability for trailer suspensions. A potential caveat is its specific suitability for Ifor Williams trailers with single parabolic leaf springs. This product is a pack of 8 high-tensile U-bolts designed for single parabolic leaf springs, commonly found on Ifor Williams trailers, and includes 16 M12 nyloc nuts.

These U-bolts are specifically designed for single parabolic leaf springs.
They are particularly suitable for Ifor Williams trailers that use single parabolic leaf springs.
The internal width is 55mm, the internal height to the thread end is 115mm, and the thread size is M12 with a 70mm thread length.
Yes, the pack of 8 U-bolts comes with 16 M12 nyloc nuts.
No, these U-bolts are specifically designed for single parabolic leaf springs and may not fit or provide adequate support for double parabolic springs.
It is recommended to check the tightness of the U-bolts after initial installation, after the first use, and then periodically as part of regular trailer maintenance.
High tensile steel is a type of steel that has been treated to have a higher tensile strength, meaning it can withstand greater stress before deforming or breaking. This makes it ideal for load-bearing applications.
Ensure the U-bolt is correctly seated around the axle and spring. Check that the threads on the U-bolt and the nuts are clean and undamaged. If threads are damaged, the U-bolt may need replacement.
Verify that you have the correct U-bolt size for your specific leaf spring and axle diameter. These U-bolts have specific internal dimensions (55mm width, 115mm height) and may not fit all applications.
Ensure you are using the provided nyloc nuts. Make sure they are tightened sufficiently but not excessively. Re-check tightness after a short period of use and periodically as part of regular maintenance.
Light surface rust can be cleaned and treated with a rust inhibitor. Significant corrosion or pitting indicates the U-bolt should be replaced for safety reasons.
