Review on Progressive Suspension 412 4079B Anodized Replacement by Tim Surridge

These shock absorbers are 100 times better than factory air shock absorbers. That should be standard on the Street Glide. No more speed wobbles, no more drawdowns and feeling like the bike is about to die beneath you. I have standard weight springs as I'm 160 and my girlfriend and I are only around 280 on the bike. I set the shock absorbers to position three and it's perfect. If you're 250 or older and riding alone, you can get a high-performance spring rating or set it to Ultra. Highly recommend, especially for this price.
