Frequently Asked Questions

Why are these bolts better than OEM?

S&S bolts use rolled threads (30% stronger), chromoly steel, and reusable design. OEM bolts are torque-to-yield and must be discarded after one use.

Can I reuse these bolts after engine rebuilds?

Yes — unlike OEM, these maintain strength and integrity across multiple installations, saving cost and downtime.

Will these fit my 2008 or older Big Twin?

This kit is for 2009-2025 model years. Verify your engine year before ordering.

What makes rolled threads stronger?

Rolling threads improves grain flow and eliminates sharp stress risers that initiate fatigue cracks, resulting in 30% greater fatigue resistance than cut threads.
