GM LS WELSH PLUG KIT & BILLET BARBELL AF64-2125

Suit GM LS Series

The Aeroflow Performance LS series welsh plug kit is a necessity when rebuilding your ls series engine. The kit includes all brass welsh plugs required, including a new barbell which is now made from 6061 aluminium. The new billet barbell replaces the factory plastic barbell which can become brittle and fatigue over time.
