Introducing the all new ProRam 58 for 12-valve and 24-valve VP44 trucks used for daily driving and towing applications. This turbo the perfect replacement for the worn out high mileage HX35 and offers great drivability and towing performance for the 300-425hp market. Based off the original Borg Warner S300G platform, the ProRam 58 uses an all new Borg Warner Forged Mill Wheel and a 360-degree thrust bearing for increased strength and durability for truck owners that expect only the best. Paired with a 65mm turbine wheel and 14cm internally gated T3 exhaust housing, the ProRam 58 will spool great, while offering better EGT control under the rigors of heavy towing.
