Fel-Pro engine cylinder head bolt set ES 72390 — OE-equivalent torque-to-yield replacement for GM V8s

Fel‑Pro ES 72390 is a complete, application‑specific cylinder head bolt set engineered to replace torque‑to‑yield fasteners with new, OE‑equivalent hardware for compatible GM V8 applications.

This bolt set provides the correct length, thread engagement and material properties to restore secure clamping of the cylinder head to the engine block after head service. Fel‑Pro designs these kits to meet or exceed original equipment standards and to simplify repairs on supported Cadillac and Chevrolet models from late‑2000s to mid‑2010s. Using a fresh, validated bolt kit avoids the reliability risks from reusing single‑use T‑T‑Y head bolts.

Which vehicles does this bolt set fit?

The ES 72390 kit targets a range of GM cars and trucks that used torque‑to‑yield head bolts. It covers late‑2000s through mid‑2010s Cadillac Escalade and CTS models, certain Chevrolet Suburban, Express and SS models, plus Escalade EXT and ESV variants. Always confirm fitment with your exact year, engine and trim before purchase.

• Compatible with 2009–2014 Cadillac Escalade ESV, Escalade, and Escalade EXT where specified
• Fits 2009–2015 Cadillac CTS and select 2010–2013 Escalade model years
• Includes coverage for 2014–2017 Chevrolet SS, 2016 Suburban, and 2010–2016 Express 4500 where applicable
• Check vehicle-specific notes using your VIN or year/make/model/engine details

Why replace torque‑to‑yield head bolts instead of reusing the originals?

Torque‑to‑yield bolts are designed to stretch within a precise range during installation; they become single‑use components. Reinstalling used T‑T‑Y fasteners risks loss of clamping force, head gasket failure, and uneven sealing. Installing new bolts restores the engineered clamp load and improves long‑term sealing reliability.

• Avoids permanent deformation and inconsistent torque readings from reused bolts
• Restores correct torque‑to‑spec clamping and head seal integrity
• Reduces the likelihood of head gasket and leak issues after head service

How does Fel‑Pro ensure fit and performance?

Fel‑Pro validates each kit for fit, form and function against original equipment requirements. The ES 72390 set is manufactured to meet or exceed OE specifications for thread, length, material grade and coating. That validation helps ensure a direct replacement without the fitment guesswork.

• Manufactured to OE tolerances for thread and length
• Material grade chosen for required stretch and strength characteristics
• Quality control testing for consistent performance and durability

What should I check before ordering to guarantee compatibility?

Confirming vehicle fit prevents returns and installation delays. Use your vehicle year, make, model, engine size and trim to verify compatibility, and review any additional notes listed in retailer fitment tools. If a fitment tool shows an information icon, read the supplemental notes carefully for exceptions.

• Enter complete vehicle details (year, make, model, engine, trim) in fitment checker
• Review any additional notes or qualifiers before purchase
• Compare part number ES 72390 to your service manual or dealer reference when in doubt
