Specs At A Glance

Good To Know

Q: Do these bolts fit every LS engine? A: They are listed for LS1, LS2, LS3, and 4.8L, 5.3L, and 6.0L variants, but thread and length requirements can vary by flexplate, so verify before ordering. A: Check your flexplate and crankshaft flange specs first.

Q: Can these bolts be reused from an old install? A: Torque-to-yield and stretched fasteners should be replaced, which is why a full kit is the safer choice for a flexplate job. A: Always follow the engine's torque sequence and spec.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
