With the parts included it give the options to set the oil pressure either stock or higher. That's a great way to account for thinner oils, lack of oil coolers, hot lapping at the track, etc.. This kit will fit ANY GM timing cover that uses the "METRIC" labeled filter adapter except the aftermarket HV covers. I've you're running a Chinese cover with the longer gears these pump gears will be too short.These are the exact same parts I use on my "earlbrown timing covers/oil systems". This is everything needed to freshen up the oil system minus the actual timing cover casting and the timing cover gasket kit. You'll notice in the image, there's a GM part number 25524990 on the filter adapter. This is not Chinese crap that's been flooding the market. These are top notch parts with excellent machining finishes and NOT covered in casting flash! Check my other listings for some cool Grand National bolt kits and MAFs!
