Fits 1985-1995 Ford Mustang GT (5.0L).

Ford Racing M-6500-R302H hydraulic roller lifters are engineered to provide the same durability and performance as the original equipment found in 5.0L High Output EFI engines. These high-performance lifters are designed as direct replacements for factory units or for use when converting a vintage non-roller engine block to a modern roller camshaft setup. When used in retrofit applications, custom-length pushrods and minor clearancing of the engine block may be required for proper operation.

• Manufactured to Ford original equipment standards for 5.0L HO EFI engines
• Direct replacement for OE hydraulic roller lifters
• 50-state emissions legal
• Suitable for non-roller to roller block conversions
• Manufacturer Part Number: M-6500-R302H

The Fleece Performance OE Replacement Rocker Arm Assembly provides a high-quality alternative to factory valvetrain components for 24-valve Cummins engines. Engineered to meet or exceed original equipment specifications, this assembly is a critical component for maintaining proper valve timing and lift. Whether you are performing a top-end refresh or replacing a worn factory unit, this direct-fit assembly restores valvetrain reliability without the premium cost of dealership parts.

• Direct-fit replacement for 24v 5.9L and 6.7L Cummins engines
• Meets or exceeds original equipment (OE) specifications
• Precision-manufactured for consistent performance and longevity
• Replaces Cummins P/N: 4995602

Fits Audi 2.0T FSI DOHC 16-valve engines.

Ferrea Racing Components lifter shims are engineered to provide precise valvetrain adjustments for high-performance Audi 2.0T FSI builds. These components are essential for tuners and engine builders who need to maintain exact valve lash and proper valvetrain geometry, especially when installing aftermarket camshafts or performance valves.

Manufactured to extremely tight tolerances, these shims ensure consistent seat pressure and timing across the entire cylinder head. This complete set provides the necessary hardware for a full 16-valve refresh or upgrade, replacing worn components with Ferrea's proven racing-grade materials.

• Designed specifically for Audi 2.0T FSI DOHC 16V valvetrains
• Ensures accurate valve lash and optimal geometry

Fits select 1987-2019 GM vehicles equipped with Small Block Chevrolet (SBC), LT, or LS-series engines originally designed for roller cams.

COMP Cams OE-Type Hydraulic Roller Lifters are engineered as a high-performance replacement for stock hydraulic roller lifters. These lifters provide a significant upgrade over traditional flat tappet configurations by decreasing internal friction and increasing valvetrain longevity. The full-travel hydraulic design allows your engine to handle much more aggressive camshaft profiles than flat tappet lifters permit, while maintaining reliable operation.

Designed for use in engine blocks originally equipped with roller cams, these lifters do not require a link bar and are compatible with factory-style lifter trays or guides. They are an essential component for performance builds or refreshes where factory-style fitment is required but improved durability is desired.

• Direct performance replacement for stock hydraulic roller lifters
• Full-travel design supports aggressive camshaft profiles
• Reduces friction and improves longevity compared to flat tappet alternatives
• Designed for OE roller cam equipped blocks
• Includes a full set of 16 lifters
• Manufacturer Part Number: 850-16

Fits select 1992-2011 Ford, Lincoln, and Mercury vehicles equipped with 4.6L and 5.4L SOHC Modular engines.

Factory lash adjusters in Ford Modular engines are susceptible to leaking down under high RPM and heavy load conditions. This bleed-down causes a loss in valve lift and duration, leading to inconsistent performance and increased valvetrain wear. COMP Cams Performance Lash Adjusters are specifically engineered with a slower bleed-down rate to ensure the valvetrain more accurately follows the camshaft profile at high engine speeds.

By maintaining more consistent contact between components, these adjusters improve overall valvetrain stability and durability. Each adjuster features a black oxide finish to provide superior resistance against rust and corrosion, ensuring long-term reliability in high-performance applications.

• Engineered for a slower bleed-down rate to maintain lift and duration
• Provides superior valvetrain stability at high RPM
• Black oxide finish protects against corrosion and wear
• Designed as a high-performance replacement for OE lash adjusters
