Manley Performance parts here are engine internals. The listings are mostly pin bushings, both wrist pin and rod pin bushings, sold singly and in the sizes the titles state. Beyond that you will find intake and exhaust valve sets and connecting rods. These are parts for an engine rebuild, not bolt-on parts.
Read the title for the application and for the size. The valves named include a Duramax intake valve kit with the head diameter, overall length and stem diameter stated, and exhaust valves for the Toyota Land Cruiser 1FZ-FE sold as a set of twelve. The connecting rods listed are Pro Series I beam rods for the 7.3L Powerstroke, with the centre-to-centre length in the title. Bushings are listed by outside diameter, inside diameter and overall length, so measure your pin and rod before you order.
Some bushing listings point to a part number they were made to replace, so check that number first. Each product page lists the years, makes and models it fits.
