Are you looking for Viper Calipers?

That is a great price for late model Viper calipers. I usually send people to Archer Racing but it is nice to have another source.

The newer Viper calipers used to be fairly reasonable to purchase new over the counter but the bean counters raised the price a bunch. I think I used to be able to buy them for about $500 a pair brand new from the local Dodge dealer.
