Buying Guide
Choosing the right aftermarket lifters for your 5.7 Hemi can seem complicated, but here are a few key things to consider:
- MDS or Non-MDS? This is the most important question. Make sure the lifters you choose are compatible with your engine’s cylinder deactivation system (or lack thereof).
- Intended Use: Are you building a street car, a track car, or something in between? The type of lifter you need will depend on your intended use. Hydraulic roller lifters are generally suitable for street and mild track use, while solid roller lifters are better for high-RPM racing applications.
- Camshaft Compatibility: Make sure the lifters you choose are compatible with your camshaft profile. Some lifters are designed for more aggressive camshafts than others.
- Budget: Lifters can range in price from relatively affordable to quite expensive. Set a budget before you start shopping so you don’t overspend.
- Installation: Are you comfortable installing the lifters yourself, or will you need to hire a professional? Some lifters are easier to install than others.
Also, consider adjustable pushrods when upgrading lifters. They allow for precise valve train geometry adjustments, ensuring optimal performance and reducing the risk of valve train noise or damage. It’s an extra step, but it can pay off in the long run.
FAQs
Q: What is the “Hemi tick”?
A: The “Hemi tick” is a common noise associated with failing lifters in 5.7 Hemi engines. It sounds like a ticking or tapping noise coming from the engine.
Q: Can I install lifters myself?
A: If you have experience working on engines, you may be able to install lifters yourself. However, it’s a complex job that requires precision and attention to detail. If you’re not comfortable with the process, it’s best to hire a professional.
Q: Do I need to replace my camshaft when I replace my lifters?
A: It’s generally recommended to replace your camshaft when you replace your lifters, especially if your old lifters have failed. This is because the lifters and camshaft wear together over time, and using a new set of lifters with an old camshaft can cause premature wear.
