Overview

BTR Delphi Gen V Hydraulic Roller Lifter Sets

BTR Delphi Gen V hydraulic roller lifter sets are designed for GM's Gen V (LT) and many Gen III/IV LS-series V8 engines to improve valvetrain reliability, particularly for performance builds or AFM/DOD conversions. These lifters are a high-quality upgrade from stock, offering greater durability and a roller wheel that rides on the camshaft, reducing friction and wear to allow for more aggressive camshaft profiles.

Additional details:

* A great service kit for your worn-out LT AFM lifter set on that AFM conversion
* Lifters will also work with Gen III and Gen IV LS engines by using a .025 - .050 longer pushrod
* Comes with BTR-exclusive handy soaking and storage trays
* Hydraulic Roller Design: They feature a roller on their base that follows the camshaft lobe, reducing friction and wear compared to older flat-tappet designs.
* Engine Compatibility: While branded as "Gen V," these are widely used in Gen III (LS1, LS6) and Gen IV (LS2, LS3) LS engines, as well as Gen V (LT) engines, often for performance builds or when deleting the Active Fuel Management (AFM)/DOD system.
* High-Quality: Delphi lifters are considered a reliable and durable component, and the BTR version includes upgrades like a high-strength tool steel body and upgraded axle.
* Installation Assistance: BTR's trays help with the necessary step of removing the stiff packing grease and soaking the lifters in oil before installation.
* Benefits:
-- Improved Durability: They offer increased strength and durability for high-performance applications
-- Reduced Friction: The roller design minimizes wear on the valvetrain and camshaft
-- Valvetrain Overhauls: They are ideal for cam swaps, top-end rebuilds, or replacing worn AFM/DOD lifters
