Frequently Asked Questions

Will these work with my factory Harley ACR (automatic compression release)?

No. S&S compression releases are controlled by starter relay, but stock HD ACRs use the ECM — they do not work together. Do not attempt to wire them together.

Can I use S&S compression releases with these heads if my bike already has factory ACRs?

No. Installing S&S compression releases alongside existing HD ACRs will damage the heads and engine. The systems are incompatible.

What engine displacement range do these heads support?

Designed for stock displacement or mildly modified engines up to 110 cubic inches.

Will these fit my 2006-2007 Touring?

This part is engineered for 2008-2016 Touring models. Check with S&S or your dealer about compatibility with 2006-2007 models.
