Lifter and pushrod rack. This rack is designed to sit in the lifter valley once the blower comes off so all the lifters and pushrods can be dropped into there spot and kept in order. Nothing is more frustrating in between round maintenance and having parts laying all over the place and not being able to remember what hole the parts came out of. This rack has nice trays to catch the oil off the lifters and the bottom tray is anodized alum. for easy clean up.
