Red Line Big Twin PowerPack For Harley

If you've got a Big Twin in your machine, the Red Line Power Pack is an easy purchase to make. It's easy because it's everything you need in one box in terms of fluids - just add a filter and go. Redline oils have a cult-like following because of the amazing amount of protection they provide to large, air-cooled V-twins.

Includes:

5 quarts motorcycle oil
1 quart V-twin transmission oil with ShockProof
1 quart primary chaincase oil
1 bottle fuel system cleaner
Long-necked funnel
Embroidered hat
Sticker kit
