Good price!! Great quality!!
Put these on my roadrunner pro and completely changed how it rides in a good way. I’m 240lb and these helped stiffen the rear and stop from bottoming out. Also the build quality feels very solid and were easy to install. There was no alignment issues what so ever just take the old ones out and slide these right in. I highly recommend these!!! They also look really nice which is a plus!!

Decent shocks for the money! Would buy again.
The packaging was nice, the appearance of the shocks is really nice, and the adjustability and ride of them is great on my Harley. Only draw back is I had to pull the bushings and use the metal inner spacers from my Harley shocks to fit the bolts for the shocks. The metal ones that came with these didn’t fit my Harley bolts, they’re all too small inner diameter. Other than that, awesome shocks! Worth the money I spent! Install was a breeze, and adjustment of the preload and air pressure was super simple. I ride 2 up on my Harley, and we’re not small. These are great for that!

Good Shock Absorbers, but Not Perfect for Every Bike
I recently installed the GZYF 13.5" 340mm Universal Motorcycle Rear Shock Absorbers on my bike, and while they offer decent performance, there are a few things to consider before making a purchase.

Cost-effective rear shock absorber, simple installation and good effect!
This motorcycle rear shock absorber has a delicate appearance and a black and silver color scheme. The installation is very smooth, the shock absorption effect is obvious, and the ride is more stable and comfortable. It is highly adaptable and suitable for a variety of models. The price is reasonable, and it is recommended!

Poor Quality Air Chambers Are Useless
No durability whatsoever. The left shock leaked the first time I used it and by the third use the right one was leaking. Now neither of them hold air. Unfortunately I didn't install them or use them right away and its been about 6mos so the return period has run out. I contacted the seller about a warranty and they just told me to contact a professional installer about putting nitrogen in them or get a new set from Amazon's stock. Not sure how nitrogen is going to help if they dont hold air. They do have some absorption without air in the chambers and they fit well on my 1992 EZGO golf cart. But they just bottom out with two people in the rear seat. Even the old saying "you get what you pay for" isn't true here

Too stiff for japanese bikes
I have a Honda cb750 and these are way too stiff. I have the preload on the softest setting.
