Review on 🚀 Unleash Your Ride with the SUPERIOR 18 1901 Rubber Spring Booster by Adrian Hayes

Bought four they seem poor quality I drilled 5 zip tie holes in each ring yes I put two donuts on each rear spool yes it has the tail and an inch lifted but that's definitely when I've tightened the compression I can carry over 150lbs of gear on my back and hardly see any drop, riding on my back is stiff which isn't unexpected. Great price, very easy to drill and install on my 2006 Prius. Raise, remove tires, spray with soap if necessary. Then simply insert the donut and feed it from the widest spread around the coil. Maybe an hour for all the work in the driveway.
