Fel-Pro camshaft thrust plate ES 73115, OEM-fit for GM & Isuzu V8s, restores camshaft endplay

When an engine’s camshaft thrust surface wears or is damaged, endplay can shift, leading to timing problems and accelerated component wear. The Fel‑Pro ES 73115 camshaft thrust plate is a direct replacement designed to meet or exceed original equipment specifications, delivering an application‑specific fit and reliable performance for a range of Cadillac, Buick and Isuzu vehicles.

Which vehicles does this camshaft thrust plate fit?

This Fel‑Pro thrust plate is made for specific GM and Isuzu V8 platforms. It covers many model years across Cadillac Escalade (including ESV and EXT variants), Buick Rainier, Buick LaCrosse/Allure and the Isuzu Ascender. Always verify compatibility with your VIN or engine code before purchasing.

• 2003–2006 Isuzu Ascender
• 2004–2007 Buick Rainier
• 2008–2009 Buick LaCrosse / Allure
• 2002–2013 Cadillac Escalade ESV and EXT (model‑year specific)

How does this part ensure correct fit and sealing?

Fel‑Pro engineers design each thrust plate to match the original geometry and mounting points so installation aligns with factory tolerances. The material selection and machining process ensure consistent thickness and surface finish, which are critical to maintaining camshaft endplay and sealing adjacent components.

• Application‑specific design for precise bolt hole and surface alignment
• Validated for fit, form and function under simulated service conditions
• Manufactured to meet or exceed OEM specifications

What benefits does replacing a worn camshaft thrust plate provide?

Installing a new Fel‑Pro thrust plate restores proper camshaft endplay and prevents further wear to the cam and timing components. That stability helps maintain accurate valve timing and reduces the risk of secondary failures that arise from excessive axial shaft movement.

• Restores correct camshaft axial clearance
• Prevents uneven wear to cam lobes and bearings
• Supports consistent engine timing and component life

What should I expect during installation and inspection?

Replacement is straightforward for a trained technician with access to factory specifications and torque values. Inspect the camshaft journal and surrounding surfaces for scoring or damage; if wear is severe, additional repairs may be required. Use new fasteners where specified and follow torque sequence to maintain plate flatness and sealing.

• Check camshaft journals for scoring or excessive wear
• Confirm endplay to factory specification after installation
• Use correct torque and sequence to avoid distortion

Who is this for? The Fel‑Pro ES 73115 is intended for professional mechanics, experienced DIYers and restoration specialists working on compatible Buick, Cadillac and Isuzu V8 vehicles who need a dependable, OEM‑level camshaft thrust plate. It’s a practical part for scheduled engine rebuilds, camshaft replacements, or whenever axial movement and sealing integrity must be restored to factory standards.
