CSF is one of the premier cooling product specialists available on the market today. One item that is often overlooked is the oil cooler. Luckily CSF has taken up the task of upgrading the oil cooler as well. If the oil runs too hot, it can lead to a reduction in wear protection and damage to the head, block, or the turbo system. This unit has 17 cooling tubes in the front with anther 6 in the rear of the cooler and still fits in the stock location without any issues.

The M50/M52/S50/S52 engines are notorious for their well-documented problems stemming from harmonics. The vibration leads to the oil pump shaft becoming weak, causing it to either break or the oil pump nut to loosen and fall off, resulting in an immediate loss of oil pressure. Worry no more! 5150 has the solution! At the core of this kit is a hardened Chromoly shaft, meticulously centerless ground to guarantee absolute precision. This shaft is designed with an exclusive square key lock system, which not only prevents the gear from ever rotating on the shaft but also reinforces the mounting area, adding additional strength. Furthermore, we replaced the problematic oil pump nut with an extended-length bolt, which is EDM drilled to accommodate safety wire for a secure fit in all conditions. Don't wait until your oil pump fails, leaving you facing expensive engine repairs! Key Features: Centerless ground shaft made from hardened Chromoly. Bolt with EDM drilling, including safety wire. Grade 8 extended-length hardware for secure gear attachment. Left-hand threaded to prevent unexpected loosening. Double-D keyed shaft and drive gear. Fully serviceable and rebuildable without the need for grinding.
