Genuine set of GM/ACDELCO lifters made by DELPHI in the USA.

8 x Performance GM LS7 Lifters (upgrade over factory with gold circlip!) (non-AFM)
8 x AFM GM Lifters.

Suits the L77 engines found in the 6.0L Holden VE and VF Holden Commodore.

We always recommend doing a DOD delete but for those wanting a drop-in replacement, these will suit.

These have a limited warranty due to factory issues with AFM lifters.
 
Genuine LS7 Delphi Lifters, made in the USA with Gold Circlip. These are a genuine lifter, however you must soak in oil 24 hours before use. You must check preload, lifter bore etc. before install. These do not come with any warranty due to too many variables that can affect lifter install.
