As you can see there are other weights listed as well. Now for the really good part, when I researched Edelbrock #5263 Coil Springs I found this page:

As you see the price is $87.95, that sounds good as it beats the best price I found elsewhere $30…however as Ron Popiel would say, “But WAIT there’s MORE!” When you click the link to it you will find that this is NOT for two springs, but rather a set of 4, bringing the cost for a set of Eibach springs in at $45 vs. $120 (the other best price I found for a quality spring). Of course you will either have a spare set, or go in with a friend and go half-zies.
