Fel-Pro camshaft thrust plate ES73115 for GM & Isuzu V8s — direct-fit, OEM-spec replacement

Fel-Pro ES 73115 is a precision-engineered camshaft thrust plate designed to restore proper cam endplay and reliable sealing on compatible GM and Isuzu V8 engines.

When a camshaft thrust plate is worn or damaged it can allow excessive endplay and metal-to-metal contact that accelerates wear. The Fel-Pro ES 73115 camshaft thrust plate is manufactured to meet or exceed original equipment specifications, using application-specific materials and validated dimensions to ensure a direct, durable replacement. This part is intended for use in the engine sealing and repair environment and is tested for fit, form and function so technicians and DIYers can install with confidence.

What vehicles and engines is this thrust plate compatible with?

This thrust plate fits a range of GM- and Isuzu-based V8 applications from the early 2000s through later model years. Fitment covers multiple Cadillac, Buick, and Isuzu platforms where the factory camshaft-retaining design matches Fel-Pro’s specifications. Always cross-check your VIN or engine code to confirm compatibility before ordering.

• Compatible applications include 2003–2006 Isuzu Ascender and select GM SUVs and sedans
• Covers Buick Rainier (2004–2007), LaCrosse (2008–2009), and Allure (2008–2009)
• Fits Cadillac Escalade and Escalade EXT/ESV variants across multiple model years listed
• Designed to match original equipment mounting and alignment points

How does the ES 73115 restore engine function?

By replacing a worn thrust plate, the camshaft’s axial movement (endplay) is controlled, preventing contact with adjacent components and uneven wear. Proper endplay preserves valve timing geometry and helps maintain consistent engine operation. The Fel-Pro plate uses materials chosen for durability in the sealing and mechanical environment of the camshaft area.

• Restores correct camshaft endplay to factory tolerances
• Prevents metal-to-metal contact that causes premature wear
• Helps maintain stable valve timing and engine performance
• Manufactured to resist the oil and heat conditions of the cylinder head

What makes Fel-Pro’s design reliable for repair shops and DIYers?

Fel-Pro validates each part for fit, form, and function relative to original equipment standards, reducing trial-and-error during installation. The ES 73115 is built with application-specific design features so mounting holes, bearing surfaces, and sealing edges align correctly. That consistency minimizes installation time and the chance of leaks or misalignment after service.

• Meets or exceeds original equipment specifications for quality and dimensions
• Application-specific engineering ensures accurate fitment without modification
• Validated on actual engine assemblies for reliable installation results
• Backed by Fel-Pro’s reputation for sealing components used by professionals

How should I install and inspect the thrust plate?

Installation requires standard engine-disassembly access to the cylinder head and camshaft area; follow vehicle service manual torque sequences and specifications. Inspect the camshaft thrust surface and adjacent components for scoring or excessive wear—replace any parts that show damage. Use proper torque and alignment tools to ensure the plate seats correctly and verify camshaft endplay meets factory limits after assembly.

• Follow the vehicle manufacturer’s service manual for disassembly and torque specs
• Check camshaft surfaces and adjacent bearings for wear before installing
• Torque bolts in the specified sequence and re-measure cam endplay
• Replace related seals or fasteners as needed for a complete repair

Who is this for: The Fel-Pro ES 73115 camshaft thrust plate is aimed at professional technicians and experienced DIY mechanics servicing compatible Cadillac, Buick, and Isuzu V8 engines. It’s particularly useful when restoring correct camshaft endplay during cylinder head repairs, rebuilds, or when addressing timing-related wear. If you need a direct-fit, OE-quality replacement that’s validated for fit and durability, this part is designed for that purpose.
