If you're working on an LS engine build or repair, you know that proper lifter alignment isn't just important—it's critical for engine longevity and performance. These LS lifter guide trays are engineered to solve one of the most common problems in LS engine assembly: lifter misalignment that can lead to premature wear, valve train noise, and even catastrophic engine failure.
These trays are designed as direct replacements for GM part number 12595365, meaning you get factory-perfect fit and function. Whether you're working on an LS1, LS2, LS3, LQ4, LQ9, L76, L99, or LSA engine, these trays provide the precise alignment needed to keep your lifters properly positioned throughout the entire RPM range.
Made from high-strength materials right here in the USA, these lifter trays can handle the extreme conditions inside a high-performance LS engine. From the brutal heat of a supercharged application to the constant reciprocating forces of a high-RPM build, these trays maintain their shape and function mile after mile.
One of the best things about these trays is how easy they are to install. As direct OEM replacements, they drop right into place without any modification needed. Whether you're a seasoned mechanic doing a complete engine rebuild or a DIY enthusiast tackling your first LS swap, you'll appreciate the straightforward installation process.
These trays shine in a variety of scenarios. They're perfect for stock engine replacements when the original trays are damaged or worn out. They excel in performance builds where maintaining proper valvetrain geometry is crucial for maximum power and reliability. And they're essential for high-mileage engine overhauls to ensure everything stays properly aligned for years to come.
When it comes to LS engine reliability, attention to detail matters. These lifter guide trays are the kind of component that you install and then forget about—until you hit 50,000 miles and realize your engine is still running as smoothly as the day it was built. That's the peace of mind you get with quality parts designed specifically for the demands of LS power.
