Good To Know

Q: Will this pin fit my 2001 LS1 engine? A: Yes, Gen 3 LS engines (including LS1) use this same dowel alignment pin. Confirm your block year and serial number for absolute fitment.

Q: Is this pin made of stainless steel? A: No, it is constructed from hardened steel for strength and corrosion resistance, not stainless steel.

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