Upgrade your GT500 timing set with these Heavy Duty Secondary chains. The factory secondary chains have been known to fail and are made with very small links. These Heavy Duty Chains are designed with link sets that will support 1500+ HP! These fit all 2007-2014 Shelby GT500 Mustangs with 5.4L & 5.8L Ford Modular engines. Will work on other 4V applications as well. JDM Engineering uses these chains on all of their Cobra Jet race cars as well as in house built GT500 Mustang engines.
Direct fit no modification required for 2007-2014 model GT500 Mustangs.
