Chrysler owners and mechanics, if you're doing valve work on your engine, this genuine Mopar push rod is exactly what you need for a proper repair. The part number 5045515AA is the real OEM deal - not some aftermarket copy that might not fit perfectly. This is specifically for intake valves and measures 7.042 inches in length with a 0.563 inch diameter. You'll typically need 8 of these for a complete set when doing a valve job. The quality of Mopar OEM parts is just superior to most aftermarket options - the precise dimensions, proper heat treatment, and exact specifications mean they'll perform exactly like your original equipment. The part has been superseded by number 53021556BB, so if you're looking up older references, that's the same part. Installation is straightforward if you're familiar with engine work - just make sure you're replacing them during proper valve service intervals or when you notice wear. I've used these in several Chrysler engine rebuilds, and they always fit perfectly and perform exactly as expected. The manufacturing consistency is what you're paying for with OEM parts - no guessing about quality or compatibility. Whether you're a professional mechanic or a skilled DIYer working on your own vehicle, using genuine Mopar push rods ensures your engine will run smoothly and quietly with proper valve operation. Don't risk engine damage with cheap imitation parts - these OEM push rods are worth the investment for reliable, long-lasting performance.
