Take Out LDK/LNF Piston(s) and Rod(s)
These are brand new, never run, take outs from assembled engines. This includes 4 new pistons/rings and rods. They come assembled and ready to drop in. They are a direct drop in replacement for the 07+ LNF (Cobalt/HHR/Sky/Solstice) and '11+LHU (Regal/Verano), but they can be installed in an LSJ however with the different piston top we recommend adding about 4-5° of timing to your tune.
Since they are new take outs, we do recommend replacing the rod bolts, however the included bolts can be reused if torqued properly. We recommend using plastigage to determine the perfect torque spec. If you order new rod bolts from the dealer, the GM part # is 90537293.
Rod bearings must be purchased separately.
