Katech Oil Pump LT4
At Griffin Motorsports, we don’t just supply parts—we build with them. We run Katech components in our own high-performance projects because they work. From street-tuned ZL1s to full-blown track builds, we’ve tested these parts where it counts. When we offer a product like the Katech oil pump, it’s because we know what it can do, and we trust it to protect the engines we depend on.
Katech LT4 Oil Pump
As everyone knows by now, the critical weak link in LT engine platform is the oil pump. Specifically the powdered metal vane housing that will crack and break apart over time creating a loss in oil pressure and catastrophic engine failure if not caught early enough. Based on owner reports, it seems to be a matter of “when”, not “if” the pump will fail, as we have seen some pumps fail at 6k miles or less, and others fail near 100k miles.
Katech saw the issue early on, and was eager to deploy their in-house Mechanical Engineer’s, 45 years of racing experience to start working on a solution immediately, but actually had a hard time getting their hands on a failed unit, because most of them ended up at dealerships for a warranty replacement.

Why The LT4 Platform Needs An Oil Pump Upgrade
The LT4 engine is a powerhouse—but like any high-output platform, it comes with demands. Originally designed for street and light track use, the factory oil pump isn't always up to the task when you're pushing more power or spending more time in the upper RPM range. Pressure stability and flow capacity can become limiting factors, especially in performance builds or aggressive driving scenarios.
Whether you're running a ZL1, CTS-V, C7 Z06 or Blackwing… or swapping an LT4 into a custom project, oil control is critical, and the OEM pump simply cannot be trusted. Cavitation, pressure drop, and insufficient volume can affect engine health under load. This is where an upgraded solution, like the Katech Oil Pump for LT4, makes all the difference. Designed to support high-RPM performance and deliver consistent pressure, it's a necessary step for anyone taking the LT4 beyond stock limits.
What Makes The Katech Oil Pump For LT4 Stand Out
When you're building for power, the details matter—and oil delivery is one detail you can’t afford to overlook. The Katech oil pump upgrade for the LT4 engine is built with performance in mind, and it solves key limitations found in the factory design. Here's what separates it from the rest:
Precision Engineering For Demanding Builds
Every Katech LT4 oil pump is precision-machined for consistency and reliability. The upgraded design helps maintain proper oil pressure across a wide RPM range—critical for high-horsepower street cars and track builds alike.
Improved Rotor And Housing Design
Katech revised the rotor profile to reduce cavitation, one of the most common issues with factory pumps under high load. Combined with a tighter, more efficient housing, this design promotes smoother oil flow and better long-term durability.
Stable Pressure, Even At High RPM
At high speeds, factory pumps can struggle to keep pressure consistent. Katech’s pump regulates oil delivery more effectively, reducing the risk of pressure drops during aggressive driving or rapid gear changes.
Built For LT4 Power Levels And Beyond
Whether you're lightly modded or going all-in with upgrades like a Kong X Port Package, and Katech Billet Front Covers, the Katech pump is built to support high-performance applications. It’s an essential component for anyone pushing the LT4 platform harder than GM originally intended.
High-Performance Benefits Of The Katech LT4 Oil Pump
Upgrading to a high flow oil pump for LT4 engines isn’t just about fixing weaknesses—it's about unlocking performance potential and protecting your investment. The Katech LT4 oil pump delivers several key benefits that make it a must-have for serious builds:
Increased Oil Volume And Flow
Higher flow means more oil gets to critical engine components, especially during hard acceleration or extended high-RPM driving. This added volume helps prevent oil starvation, a common risk in aggressive driving conditions.
Enhanced Engine Longevity
Stable pressure and reduced cavitation translate into less wear on engine internals. With the Katech pump, you’re helping to extend the life of your LT4 by keeping everything properly lubricated, no matter how hard you push it.
Consistency Under Stress
Track days, drag passes, or boosted street builds put enormous stress on the oiling system. The Katech pump delivers consistent performance under demanding conditions—giving you peace of mind when it counts.
Supports Other Power Mods
Adding power means more heat and stress on the engine. Paired with other upgrades like the GMS Stage.II Supercharger Cooling Package, this oil pump helps your setup stay balanced and reliable.
How The Katech LT4 Oil Pump Handles Real-World Performance
It’s one thing for a part to look good on paper—and another for it to perform reliably under pressure. The Katech LT4 oil pump was built for exactly that. Here's how it holds up across the kinds of real-world conditions LT4 owners face every day:
Reliable Street Performance With High Power Builds
Even in street-driven LT4s pushing well beyond stock numbers, the Katech pump keeps pressure consistent across daily driving, spirited runs, and long-haul conditions. Whether you’re stuck in traffic or hitting a backroad, stable oil flow means no pressure dips or startup clatter.
Consistency During Track And Strip Use
Extended high RPM operation can overwhelm stock pumps, but the Katech pump stays locked in. It handles the oiling demands of aggressive launches, quick shifts, and sustained throttle without cavitation or loss of flow—ideal for drag and road course setups.
Supports Forced Induction And Heat-Heavy Environments
Adding more boost means more heat and more demand on your oiling system. The Katech pump is built for high-output environments and pairs especially well with cooling upgrades like zl1 cooling mods, helping to maintain oil pressure even under heavy thermal load.
LT4 Oil Pump Replacement: What To Know Before You Install
Swapping out the factory unit for a Katech oil pump upgrade is one of the smartest moves you can make for long-term performance. But like any precision part, proper installation is key to getting the most out of it. Here's what to keep in mind before starting your LT4 oil pump replacement:
Proper Fitment Is Crucial
The Katech pump is designed as a direct-fit upgrade for LT4 engines, but verifying compatibility with your specific build—Camaro ZL1, CTS-V, or crate engine swap—is a smart first step. Check clearances and tolerances before buttoning everything up.
Pair With The Right Hardware
Consider replacing or inspecting your timing cover gasket, oil pickup tube O-ring, and crankshaft bolt during installation. These small components play a big role in preventing future leaks or pressure issues.
Don’t Skip The Break-In And Testing
Once installed, monitor oil pressure and engine behavior during initial startup. This is where having tools like Banks iDash becomes especially useful. You’ll want real-time feedback to ensure the pump is performing as it should.
Professional Installation Is Recommended
If you're not familiar with internal engine components, we recommend having a qualified performance shop handle the install. It’s a straightforward job for someone experienced, but attention to detail matters—especially when dealing with high-performance engines like the LT4.
When To Upgrade Your LT4 Oil Pump
Not every build starts with an oil pump upgrade—but there are certain moments when it becomes the smart next step. Knowing when to replace your LT4 oil pump can prevent costly engine damage and keep your build performing at its best. Here’s when to make the move:
During A Camshaft Or Timing Set Install
If you’re already opening the front of the engine for a camshaft swap or timing components, that’s the perfect time to install a high-flow oil pump. You’re saving labor and giving your new components the pressure and flow they need to operate safely.
After Noticing Oil Pressure Instability
Fluctuating pressure readings—especially at idle or under load—are signs the factory pump might be struggling. Replacing it with a performance oil pump for LT4 engines like the one from Katech helps resolve pressure drop issues before they turn into bearing damage.
As Preventive Maintenance On High-Mileage Engines
Even if your LT4 is still running fine, high mileage can mean wear on the oil pump’s internals. Upgrading now—before failure—adds confidence and longevity to your build, especially when paired with other camaro zl1 parts for a full refresh.
