Dalton billet 35 deg helix
TD recommended helix for all TD tunes.
Très satisfait du résultat avec deux ressorts d'embrayage.
High quality if you have a sidewinder this is a must puts rollers on secondary in contact at all three rollers and upshift and backshift is 100% better road 400 miles last weekend on trail at speeds of 80mph to speeds of 126mph all day with powertrail tune and turboforce muffler and cold air intake very hard riding and my belt temps were way down , I reamend to put new bushing in the back of secondary and the DALTON HELIX I am no longer blowing belts well worth the money !!
