Go to "Seller's Store", there are a number of different ones. Actually, I didn't get the heavy duty, which is fine with me. Find the model number and go to Progressive's web site. Also have front springs for $10, alas, not for our bikes.
I was initially worried that these may be priced per piece, or each. Everything on there is plural, and it says "sold in pairs". The outfit has a huge feedback number, I'll be eagerly watching for the UPS man.
