Has anyone done this modification to their trucks? I used the ASP Pulleys on a 2000 Mustang and it did make a bid difference of about 10hp at the wheels. It made the engine rev so much easier I thought. I know the mod doesn't add more horsepower or torgue but it lets more through to the rear wheels! ASP seems to be about the best company for Pulleys so what does everyone think?

  I have a 2018 Silverado Custom with 156k on the odometer. In the last month I've replaced the plugs, wires and the driver side engine mount. My wife just returned from a trip of about 1500 miles and told me the brakes are making a grinding noise when applied. I drove it and looked it over and this is what I found with the driver's side rear rotor. I'm going to order new pads and check about having the rotor resurfaced. Hopefully this is easier than the last 2 jobs. Peace

  Any update if the new valve cover help with the oil consumption? I have a 2014 GMC sierra and my truck is consuming a lot of oil so I’m wondering if replacing the driver side valve cover will stop some of the oil consumption. Thanks

  I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time. They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites. Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible. If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.
