Description

This precision CNC-machined valley plate by Lokar replaces the stock 11-bolt valley pan on Gen IV LS engines. Constructed from 3/8-inch billet aluminum, it features a high-efficiency breather assembly and an external port, allowing the Gen IV LS engine to breathe more effectively. The design incorporates integral O-ring bosses that block off Displacement on Demand (DOD) passages, negating the need for a separate DOD delete kit. Installation requires relocating the oil pressure sender, for which a billet aluminum remote mount is included. The GMLS2004M comes with a machined finish and includes all necessary O-rings, seals, and stainless steel fasteners for a complete installation. It's important to note that this valley plate does not include provisions for oil filling. Made in the USA, this product comes with a lifetime warranty.
