When changing to these do you need a different length belt? Thanks

Changing only the damper will require a shorter belt.

If installing a small diameter damper and a large WP pulley the stock belt will work but is a bit long. I recommend a 1" shorter belt with this combo.

Changing the damper, WP and alt pulley will also require a shorter belt.

Changing the damper, wp/alt and hydraboost pulleys will require a 1" longer belt.
