    Trailer spring with you bolt kit.

    Worked as it should.. except for the you bolt nuts. Had a hard time getting them to started. Than realized they wear lock nuts. All the years of changing springs. First time I've used a lock nut on a you bolt. Not to sure about that. I'd rather of used a casolated nut. For the fear of not getting the rite torque with the lock nut.

    Great product and customer service!

    Packages arrived and we were missing a spring. Product was shipped but one of the springs was lost in the mail. I called customer service and they immediately sent a replacement part. Great products and awesome customer service! Will be a returning customer in the future!
