The LS Oil Accumulator Adapter Body is a precision-machined solution designed for GM LS-based engines, allowing seamless integration of an oil accumulator into your build. By providing a dedicated connection point for -10 AN plumbing, this adapter makes it easy to route pressurized oil to and from an accumulator system. 

Built from billet aluminum and machined to precise tolerances, this adapter delivers long-term durability and leak-free performance in high-stress environments. It’s a critical upgrade for performance engines that see hard acceleration, steep angles, or sustained high-RPM operation where oil pressure stability is essential.

Includes:

  • (1) LS Oil Accumulator Body
  • (1) Gasket
  • (2) 1/8" NPT Plugs
  • (1) Selected Adapter (Straight or 90°)

Tech Insight 

 Oil starvation is one of the leading causes of engine failure in high-performance and off-road applications. During hard acceleration, braking, or extreme angles, oil can move away from the pickup, causing a momentary loss of pressure. An accumulator system solves this by storing pressurized oil and delivering it instantly when needed.

Using a properly designed adapter body ensures consistent oil flow and reliable sealing under pressure. Pairing this with quality AN plumbing and proper system setup is key to maximizing engine protection and longevity.
