AMS Racing V2 Lifters Review: Are They the Real Deal for Your Engine?
Alright, let's talk about something that might not always be front and center in every build discussion, but trust me, it's absolutely critical for your engine's health and performance: lifters. Specifically, we're diving deep into the world of AMS Racing V2 Lifters review. If you've been around the block a few times with performance engines, you know that a bad set of lifters can turn a dream build into a nightmare faster than you can say "valve float." So, when it came time for my own engine refresh, I did my homework, and the AMS Racing V2s kept popping up. Now, after spending some quality time with them, I'm ready to spill the beans on whether they're worth the investment.
Why Lifters Are a Bigger Deal Than You Might Think
Before we jump into the AMS Racing V2s, let's quickly underscore why these little guys are so important. Think of them as the unsung heroes translating the rotary motion of your camshaft into the linear motion that opens and closes your valves. They're constantly under immense pressure, dealing with heat, friction, and the relentless hammering of engine cycles. When lifters go bad – whether it's collapsing, ticking like a time bomb, or just generally wearing out – you're looking at lost power, excessive noise, and potentially catastrophic engine damage.
For performance applications, the stakes are even higher. High RPMs, aggressive cam profiles, and stiffer valve springs demand a lifter that can not only survive but thrive. You need consistency, excellent oiling, and the ability to maintain valve control without protest. This is where "racing" lifters come into play, promising better durability and performance characteristics than your average OEM replacement. And that's exactly the niche the AMS Racing V2 Lifters aim to fill.
Enter the AMS Racing V2 Lifters: First Impressions and Build Quality
So, the box arrives. You know that feeling, right? Like Christmas morning, but with more grease and less wrapping paper. Pulling out the AMS Racing V2 Lifters, the first thing that strikes you is their heft and precision. They just feel solid in your hand, not like some lightweight, cheap stamped component. You can immediately tell these aren't your grandpa's lifters.
AMS Racing has clearly put some thought into the "V2" aspect, indicating an evolution from an earlier design. While I don't have direct experience with their previous version, the improvements typically focus on better internal oiling, reduced mass for higher RPM stability, and enhanced materials for longevity. Visually, the machining is top-notch, with smooth surfaces where they should be and precisely machined oiling holes. The overall finish inspires confidence – something you definitely want when you're trusting these parts with your entire valvetrain. It's like comparing a budget screwdriver to a Snap-on; both do the job, but one just feels right.
Installation: No Surprises (Which is a Good Thing!)
Let's be honest, nobody enjoys an engine build where parts fight you every step of the way. Thankfully, the installation of the AMS Racing V2 Lifters was pretty straightforward. If you've installed lifters before, you won't encounter any curveballs here. They dropped right into place without any fuss in my LS-based block.
Of course, the usual precautions apply: make sure everything is scrupulously clean, pre-oil them properly (don't skip this step!), and ensure you follow your cam manufacturer's recommended break-in procedure. For me, that meant a proper soak in engine oil before installation and then adhering to the cam break-in with a quality zinc-rich oil. It's like priming a pump; you want them fully charged and ready to go from the first crank. This might sound obvious, but it's often overlooked, and with performance lifters, doing it right ensures you get the most out of them.
Performance on the Street & Track: Quiet Power
This is where the rubber meets the road, or more accurately, where the lifter meets the cam lobe. After the initial break-in, I immediately noticed a difference.
No More Ticking Time Bomb
My previous lifters (an older, tired set) had developed that infamous, annoying tick – not super loud, but enough to make me constantly paranoid. With the AMS Racing V2s, that tick is gone. The engine sounds significantly quieter and smoother at idle, which is a massive relief. It's like the engine is finally whispering instead of complaining. This isn't just about noise; it's an indicator of proper valve lash and stable operation.
Engine Smoothness and Rev-Happiness
On the road, the engine just feels happier. It revs incredibly smoothly through the entire RPM range, with no hesitation or perceived valve float even when pushing it hard. Whether I was just cruising on the highway or laying into the throttle for an aggressive pull, the valvetrain felt tight and responsive. For anyone running an aggressive cam, this stability is crucial. There's nothing worse than an engine that feels like it's fighting itself at high RPMs.
Did they add a ton of horsepower? Directly, probably not a noticeable amount. Lifters aren't designed to be power adders in themselves. However, by ensuring precise valve control and eliminating any potential for valvetrain instability, they allow your engine to realize its full potential from your cam and cylinder heads. It's like having a perfectly tuned orchestra; every instrument (component) plays its part flawlessly, allowing the whole symphony to sound incredible.
On track days, I pushed the engine hard, hitting the rev limiter numerous times. The AMS Racing V2 Lifters held up admirably. No signs of stress, no change in engine note, just consistent, reliable performance. This is where the "racing" in their name truly earns its stripes.
Durability & Long-Term Reliability: Built to Last?
One of the biggest concerns with any performance part is how it holds up over time. It's easy to make something perform well for a few dyno pulls, but real quality shines through after thousands of miles and countless heat cycles. So far, after a good chunk of miles and several oil changes, the AMS Racing V2 Lifters are holding strong.
I've been running a quality synthetic oil, and during my most recent oil change, I pulled a sample for analysis. No excessive metal particles indicative of abnormal lifter or valvetrain wear, which is a fantastic sign. The engine continues to run as quietly and smoothly as it did after the break-in. This speaks volumes about the materials and design choices AMS Racing has made. The "V2" isn't just a marketing gimmick; it truly seems to represent a refined, durable product. For me, knowing that my valvetrain is robust and won't be a weak link in the chain provides immense peace of mind.
