When building or upgrading a high-performance GM LS or LT engine, one critical component often determines whether your engine thrives or fails: oil pressure stability. Whether you are putting down quarter-mile passes, carving up track days, or running a high-horsepower street build, your factory oiling system faces extreme stress at elevated RPMs and sustained high loads.
We are excited to announce that we are now carrying Katech Performance Oil Pumps for GM LS and LT platforms—giving your build the ultimate insurance policy in high-efficiency engine lubrication.
Why Oiling is the Weak Link in High-Performance LS & LT Builds
Factory LS and LT oil pumps perform fine under stock conditions, but as horsepower, valve springs, RPM limits, and oil temperatures rise, the OEM pumps hit their limit:
-
Oil Cavitation: At high RPM, standard rotor pumps can cavitate, causing severe pressure drops precisely when your bearings and valve train need protection most.
-
Housing Deflection: Factory cast housings can flex under extreme load, leading to internal wear and inconsistent pressure delivery.
-
Volume Shortages: High-lift camshafts, upgraded pushrods, and forced induction setups demand precise oil flow that stock pumps struggle to maintain steadily.
Katech engineered their billet oil pumps specifically to resolve these issues on the track and dyno.
The Katech Difference: Engineered for Maximum Pressure & Reliability
Katech isn't just an aftermarket brand—they are legendary motorsports engineers with decades of Corvette Racing and GM factory powertrain heritage. Their oil pumps are widely recognized as the industry standard for a reason:
1. Precision CNC-Machined Billet Housings
Unlike cast OEM units, Katech pumps are precision CNC-machined from solid billet aluminum. This eliminates housing flex and ensures tight tolerances under intense heat and mechanical stress.
2. Ported & Anodized Internal Flow Passages
Every Katech pump features ported oil passages to maximize fluid dynamics, reduce restriction, and minimize cavitation at high RPMs. The hard-anodized coating prevents internal wear for maximum durability over the life of your engine.
3. Optimized Port Scavenging & Pressure Control
Whether you run a wet-sump or dry-sump setup, Katech pumps deliver consistent oil pressure without parasitic drag, preserving horsepower while protecting your crank, rods, and main bearings.
Applications: Finding the Right Pump for Your Build
We now stock Katech oil pumps for both wet-sump and dry-sump configurations across the entire LS and LT engine families:
| Engine Family | Typical Applications | Highlights |
| GM LS (Wet Sump) | LS1, LS2, LS3, LS6, 4.8L/5.3L/6.0L Truck Engines | Ported design, anti-cavitation rotor set, direct bolt-on replacement. |
| GM LS (Dry Sump) | LS7, LS9, Grand Sport Corvette | Enhanced scavenge capacity, high-volume pressure stage for high-g cornering. |
| GM LT (Wet & Dry) | LT1, LT4, L83, L86 | Variable displacement optimization, billet housing durability for supercharged and high-revving N/A setups. |
Ready to Protect Your Engine Investment?
Don't let a weak oil pump destroy thousands of dollars in engine parts. Upgrading to a Katech oil pump during your next cam swap, head build, or complete engine overhaul is one of the smartest upgrades you can make.
