This Stage 8 Locking Flexplate Bolt Kit is designed for a 1979-1995 Mustang GT, LX, or Cobra 5.0 V8 with automatic transmission.  No more worrying about the flexplate coming loose with these bolts.  We have used Stage 8 locking bolts for over 10 years and have never experienced a single bolt backing out.  Most factory bolts are designed to be used only one time, these Stage 8 bolts are hardened to be much stronger and can be reused over and over again.

Stage 8 manufactures the world’s best active mechanical locking systems.  Their locking fastener solutions are fail-safe when used and installed as directed.  They are removable and reusable and can be visually inspected; if the locking retainer and clip are present then no fastener rotation has occurred.  Their locking systems are used on the Space Shuttle, Caterpillar Tractors, Ford Racing, Armored Combat Vehicles and many other applications.  Their locking Header Bolts are easy to use and they are a real assurance against horsepower loss or gasket failure created by loose nuts or bolts.  The unique patented and trademarked functional design is just three pieces: a bolt (4130 Allow Steel), a locking retainer and a spring clip.  These header bolt kits are application specific hex head with a 3/16 recessed allen head.  All kits are sold with all the necessary hardware for your application
