• Premium Total Seal AP ring set included (Comes standard with 1.5mm x 1.5mm x 3.0mm ring pack that consists of 440B Stainless Steel Tops with a C33 Face Coating, Taper Hook Groove Napier second rings and a 3-piece soft-nitrided rail flex vent oils, specially designed for severe duty applications such as nitrous blowers and turbo engines.)

  Note on rod small end widths - These piston forgings have a minimum pin boss span of 1.060, this is because they also use a 2.250 long wrist pin, to this gives the wrist pin .595 of engagement In the pin bore. Many aftermarket rods including BTR's 6.125 LS rod set (BTRROD6125H1-8) have a small end width of 1.060 or more and will need to have the small end narrowed by a respectable machine shop by .080-.100" for proper fitment. Carrillo & Bullet rods use a .900-1.000 wide small end, so there is no need for additional small end clearancing.
