My 1993 gl1500 Aspencade has 100,000 miles knit and needed shocks. After a failed atte.it fireplace them with used airshocks I purchased these and getting for of the air shock. This was the best money I've ever spent on motorcycle parts ever. I weigh 250# and my wife weighs 180# and adding heavy cargo on the bike and a heavily loaded trailer I set the suspension on level 3. And in over a thousand mi!es of road now it never bottomed the suspension one time. It was perfection. The bike handled like an eager young athlete. I would recommendations to everyone.
