Customers appreciate the high-quality and perfect fit of our U-bolts, particularly when used with 2-inch wide springs for vehicle suspensions. Noted as better than original parts, users have found our U-bolts superior to cleaning and reusing old ones, even if they're in good condition. Customers had to modify their setups slightly due to the bolts being shorter than original Chevy versions. Additionally, users suggested that included washers could be upgraded to hardened SAE versions for enhanced performance. Successful applications include classic Chevy models and the product is confirmed as an effective local replacement solution.

Works great for 2 inch wide springs
Used these to replace stock u bolts on 1957 Chevy 3100. Worked fine but uses lock nuts and flat washers vs stock lock washer with nuts. Wondering if the lock nuts are single use. May clean up the stock nuts and washers for spares.

Good
These u-bolts are about an inch shorter than the original Chevy u-bolts. They will barely accommodate the stock leaf spring pack, forget about adding lift blocks unless you take a couple leafs out, there isn't enough thread length.

They fit perfectly, much better than dealing with cleaning the stock ones as much as I'm for using stock parts if they are in good condition.
