These springs were exact replacements for the springs I am replacing after they started spreading and broke due to driving dirt roads.These are heavy and not easy to install but is much more manageable with a second set of hand. Keep in mind the hardware used for these are single use and should always be replaced with the springs. Also, I would highly recommend the use of impact wrench. This job would have sucked if by ratchet.

If I didn't need this boat trailer to be functional immediately, I would have sent this junk back. NONE of the hangers fit correctly. Everyone of them needed to be reworked to fit the springs. What should have been about a 2 hour job turned into 5 plus hours. Not that I needed printed instructions, but there were no instructions included. Reading the reviews, some were good, some were not. This tells me there is zero quality control at the manufacturer. This is typical with all the Chinese made items that I've purchased on Amazon. I will not purchase from this vendor again. I will be removing and replacing these springs/hangers at my earliest convenience and will purchase locally. Hopefully they stay together until then. Trying to save money on Amazon backfires sometimes.
