The E-Z-GO Medalist TXT Heavy Duty U-Bolt is a part that you might think you could get away with without upgrading. You would be wrong. Think about what this golf cart u-bolt supports. You are talking about significant suspension pieces. These components directly secure the leaf springs to the frame of the cart. Once you add heavy-duty springs so you can carry heavy loads, it means replacing the bolts that support them with heavy-duty hardware.This is the stress point for all the weight the spring supports. The last thing you need is an OEM u-bolt to sheer and slam the brand new heavy-duty leaf spring you just installed into the pavement. This is not something you want to experience. Imagine it happening at high speed while towing a heavy load; because that's when it's going to fail. Now you have a down golf cart and a load that has to be rescued.
