Thank you for checking out our products! What we have here is our adjustable rear shock for the 2013-2023 Honda Grom or anything that can use a 240mm-260mm shock absorber. This is a well-built and beautiful shock. We have definitely put them through the paces before we released our version to the public. Everyone who ran them immediately could tell the difference between the stock shock and our adjustable shock. It was nice to be able to fine tune for the weight of the rider, riding environment,and / or if you have a passenger. This shock will definitely not let you down. We stand behind all of our parts. We don't bail after the sale. If for any reason you are not pleased with your purchase, reach out to us, and we will definitely make sure your experience is the best and expectations are met (within reason, of course). If you want to do the install yourself, we are here to help walk you through it. If you have any questions about our products, please feel free to reach out to us. If you are looking for a little bit more out of your rear suspension, we also carry a remote reservoir double adjustable rear shock for the rider wanting to squeeze every last ounce out of their suspension It is in a separate listing.
