Frequently Asked Questions

Do I get both front and rear cylinders in this order?

No — this is a single cylinder. You must order two (one for each side) plus matching pistons to complete a set.

Can I use this with my existing pistons?

No — the cylinder must be finish honed and matched to new pistons for proper fit. Pistons are sold separately.

Is this ready to install out of the box?

No — finish honing and piston matching are required before installation to ensure compression and ring seal.

Will this work on stock 80-inch Shovelheads?

Yes, as a replacement cylinder. It also supports bigger bore upgrades if you use larger-diameter pistons.
