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 other fail near 100k miles, it just seems to be a matter of time.
Katech saw the issue early on, and was eager to deploy their in-house Mechanical Engineer’s leveraging their 45 years of racing experiance 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.
Once they did, R&D started in mid 2020, with the formal release in February 2021. Katech’s solution was somewhat simple. Replace all of the powdered metal pump internals with steel billet, design the pump with tighter tolerances, blueprint each one for the highest quality pump on the market. Something they have been doing on the LS platform since 1997 when those pumps started to fail due to tolerance issues.
Although the LT pumps are failing for a different reason, Katech identified the issue yet again, and implemented there engineering team to solve the issue once again, and create another gold standard for our LT oil pump upgrades.
Now just about four years and 2,500 units later, Katech has yet to see one failed Katech unit with a broken billet vein gear or loss in oil pressure, which why so many of us consider this the “no brainer” upgrade, when it comes time to upgrade your camshaft.
Key Benefits;
Superior peace of mind for all builds from mild to wild.
Installs using existing GM OEM process and procedure.
Consistent oil pressure at all RPM’s and all applications.
No tuning, Alignment or Special Installation tools required.
Billet Steel internals replace the OEM powdered metal parts.
If you are like us, and enjoy wrenching on your car, as much as you do driving them, then I am sure you are already mulling the idea of doing this yourself, and saving the $4-5k many shops will charge to replace your oil pump and some common bolt-ons while the engine is out of the car. Considering the labor involved to replace an oil pump, it has been a common practice to combine this upgrade along with a typically head and cam package install, as it utilizes most of the necessary labor to achieve. That is exactly what we did to our in-house 2022 ZL1 when we pulled the motor at 2,000 miles in order to replace our pump. We not only have alot of resources that we can share for the DIY builder, but we can build you a custom parts bundle that will simplify your build, save you money, and can even help with recommending a remote tuner providing you more control for those of you that live in a performance shop desert like me.

Katech Wet Sump Billet LT Pump KAT-A7502.
Installation Hardware & Installation Instructions.
Note; although not yet available through the website, because we are a proud dealer for Katech parts, we can put together a turn-key head and cam package for your build from mild to wild, helping you take advantage of the labor needed to replace the OEM ticking time bomb. Email us at info@griffin-motorsports.com and lets discuss your build goals, and let us help you create a custom bundle for maximum savings!
Not yet ready to replace your pump? Worried about how to monitor your pressure and perhaps catch a drop in pressure before you spin a bearing? Than you need to look no further than our Banks iDash gauges. Although there a over a dozen benefits to these beauties, one key feature for us LT4 users is the high and low alert functions, that will give you the piece of mind driving after you set a “low pressure” alert at around the 28psi level which is already several PSI less than a target hot idle of 33psi… and will give you the real-time notification that there may be a problem, giving you the critical time to shut down, before severe damage can be done.
Food for thought, none the less.
What you need to provide;
Patience and attention to detail for installation if you are doing this DIY style like we did... or, someone like that, who you trust with your beloved, adorned, magnificent, earth shaking, alarm sounding LT4 powered beast!
A lot of supplemental parts to install, and several parts to consider upgrading while replacing this pump. Email us at info@griffin-motorsports.com and lets discuss your build goals, and let us help you create a custom bundle for maximum savings!
