Some kits are specifically designed for MDS-enabled engines, retaining the cylinder deactivation feature for fuel economy, while others are non-MDS kits, often referred to as MDS delete kits, which aim to provide consistent 8-cylinder performance and eliminate common MDS-related failures like lifter tick. Knowing whether you want to keep or remove MDS is foundational to your choice.
Next, consider the scope of the kit. A “top end kit” can range from just gaskets to a complete overhaul including camshafts, lifters, valves, and even pistons. Assess your engine’s needs: Are you just replacing worn gaskets, addressing a specific issue like a bad lifter, or undertaking a full engine refresh? Kits that include new camshafts and lifters are crucial for addressing the dreaded Hemi tick. More comprehensive kits might also include timing components, oil pumps, and water pumps, offering a more complete solution for a tired engine. Always check the specific components included in any kit.
Material quality and manufacturing processes are also paramount. For instance, Cometic’s MLS gaskets are renowned for their durability and sealing capabilities. For internal components like camshafts and lifters, look for reputable manufacturers known for precise machining and quality control. Aftermarket kits can offer significant savings, but carefully review customer feedback regarding component integrity and fitment. Finally, ensure the kit’s year and model compatibility with your specific 5.7L Hemi vehicle. Minor variations between model years (e.g., 2009-2017 vs. 2009-2015 Rams) can mean the difference between a perfect fit and significant installation headaches.
Budget Planning
Your budget will significantly influence the type of 5.7 Hemi top end kit you can afford. Basic gasket kits are the least expensive, typically ranging from a few hundred dollars. Comprehensive camshaft and lifter kits fall in the mid-range, often costing between $800 to $1,500, depending on the brand and additional components like head gaskets. Full overhaul or rebuild kits, which include pistons, timing chains, and pumps, are the most expensive, often starting from $1,500 and going upwards, especially if they include high-performance components.
Beyond the kit itself, remember to factor in installation costs. A 5.7 Hemi top end rebuild is a labor-intensive job. Professional installation can easily add $1,000 to $3,000 or more, depending on your shop’s rates and the complexity of the kit. If you’re a DIY enthusiast, you’ll save on labor but still need to account for specialized tools (e.g., spring compressor, torque wrench, engine stand), shop supplies (cleaners, lubricants), and potentially ancillary parts not included in the kit (e.g., new head bolts, specific sealants, fresh oil and coolant). Sometimes, a seemingly cheaper kit might require you to purchase several missing but critical parts separately, eroding any initial savings. Always compare the total cost, including all necessary components and labor, before making a final decision.
Final Thoughts
Investing in a quality 5.7 Hemi top end kit is a proactive step towards maintaining or restoring the powerful performance of your engine. Whether you’re addressing an existing issue like the infamous Hemi tick or planning a performance enhancement, the right kit can make all the difference.
