Are you looking to upgrade your factory steel spring retainers to stronger and lighter weight retainers? We here at JDM recommend the Crower Chromoly retainers and use them on all of our in house builds. Stronger than factory and also lighter weight for maximum performance. If you are racing your GT500, upgrading your cams, or just looking to make big power then upgrading your spring retainers is a step to not over look.
Fits 2007-2014 GT500 Mustangs
