2.5″ GM Truck “Triangle” Flange


This 1/2″ thick flange is made from 1018 MS and fully CNC cut to fit the “triangle” style manifolds (passenger) for the Gen III/GenIV trucks (4.8L, 5.3L, 6.0L, 6.2L). With 2.5″ ID it can be used for 2.5″ exhaust, or making up-pipes for turbo setups that mate to truck manifolds.
