The LT Accumulator Body is a precision machined oil adapter designed specifically for GM LT-based engines, allowing you to integrate an oil accumulator into your build for serious engine protection.

An oil accumulator stores pressurized oil and instantly releases it when oil pressure drops — protecting your engine during hard acceleration, braking, off-camber angles, rock crawling, drifting, autocross, or track use.

-10 AN Integration
Designed to work with -10 AN plumbing for secure, leak-free oil routing.

Modern LT engines are incredibly capable — but like any performance engine, they rely on consistent oil pressure for survival.

In off-road applications especially, vehicles often operate at severe angles where oil can momentarily move away from the pickup. An oil accumulator provides an immediate buffer during these moments. If you’re investing in a quality LT swap, protecting that investment with proper oil management isn’t optional — it’s smart.
