LT4 Billet Supercharger Lid
We all know arriving fashionably late to the party comes with risks, but in the world of aftermarket performance parts, that’s not always a bad thing. In fact, it can be the perfect opportunity to step back, observe the competition—what works, what doesn’t—and then innovate where others fall short. And that’s exactly what Matt and the team at DMS did with this stunning blend of engineering and ingenuity.
Let’s face it: Many of the current options for the LT4 lid are… lackluster, at best. Too often, aftermarket solutions are either overly simplistic or downright unattractive, with little to no measurable performance gains. All relevant client feedback that DMS took into account, knowing they could do better.
Instead of aiming low and breaking the lowest price barrier, they aimed high, and set their sights on breaking the mold. The mission? To create a lid with one clear goal: optimized airflow. That’s where Verus Engineering’s genius came into play.
With all of the knowledge and high tech equipment on hand, Verus’s airflow simulations quickly revealed that if this lid was going to outperform the competition, it needed more than just a tweak here and there—it needed an entirely unique, sculpted design that catered to the needs of airflow dynamics, not one that catered to being simple and flat. The lid needed a design that would only be possible with an upgraded process and equipment. And so, they cut Verus loose to utilize their amazing $650K DMG Mori 5-axis CNC machine to bring this vision to life. The result? A complex, yet beautiful shape designed to channel and balance nearly perfect airflow into each intake runner, providing smoother air distribution.
What you will quickly notice once you receive your LID is the extra height. Approx. .25” taller than OEM and nearly 1/2” taller than the leading competition which results in approximately 25% more plenum volume which provided Verus the space needed to create that elegant curved profile. For those of you with port-plates, I tested hood clearance using my GMS High Flow Hood Bracket and I still had 1.2” of clearance. Although this is not the lightest lid on the market, it does save you more than 1 pound over the OEM lid.
While many competitors take the easy route, using flat designs cut on simpler 3-axis machines to keep costs low, the DMS lid takes a more refined approach. It’s crafted from a solid 70lb piece of 6061 aluminum bar stock, meticulously machined on a state-of-the-art, 5-axis CNC machine, demanding more time, more material, and, of course, more performance. The payoff? A stronger, larger, and higher-performing part that adds just the right amount of supercharger whine, while delivering an eye-catching, show stopping design like nothing else on the market. This lid was designed for those who want to stand out from the crowd by putting the very best on there car.
Preliminary testing results speak for themselves: On a stock 2018 CTS-V, DMS saw a healthy 20hp gain across the entire RPM range—proof that innovation pays off, and a strong focus on form, can transform into improved function. Which is why the DMS Billet Lid, is the Griffin Motorsports LT4 Lid of choice. Stay tuned for more testing results on our 900hp ZL1.
Fitment: 16+ CTS-V + 17+ ZL1 Camaro + C7 Z06 + Cadillac CT5 Blackwing
*Will not work with CTS-V or ZL1 strut bar without spacers.
*C7 Z06 may need to modify or remove the hood liner to fit..
*New lid hardware included. Reuses GM green o-ring around the perimeter.

Note: The finish in the top of the LID shown is slightly more matte than comes out of the box. After test fitting my lid, I saw a few small blemishes so I decided to buff out the entire lid with a polish compound. The lid comes a little more reflective than you see in the photos. Although you can’t really tell from the photos, I wanted to be transparent.
Long story short, you will LOVE this lid, as it is easily the best looking lid currently available for the LT4 engine.
