Ecotec Upper Timing Guide Rail Stepped Shoulder Bolt – Billet Fix for Common Factory Failure

Eliminate the risk of catastrophic failure with the BK Racing Ecotec Stepped Shoulder Bolt Replacement — the best upgraded shoulder bolt for GM Ecotec 2.0L, 2.2L, and 2.4L engines, specifically engineered to replace the notoriously weak factory stepped bolt that frequently shears off, often damaging the cylinder head in the process. This billet upgrade is an absolute must-have for every Ecotec owner — preventing expensive repairs and downtime in Cobalt SS, Ion Redline, HHR SS, Solstice GXP, Saab 9-3, and all Ecotec builds.

Precision CNC-machined from high-strength materials with superior tensile properties and precise geometry, this bolt far exceeds OEM durability — resisting breakage under high loads, vibration, or heat cycles where the stock bolt fails. No more worrying about head damage from a snapped factory piece — install once and forget it.

Key Features:

• Billet construction for unmatched strength and fatigue resistance
• Exact dimensions for direct, drop-in replacement — no modifications needed
• Corrosion-resistant finish for long-term reliability
• Critical fix for the common Ecotec shoulder bolt failure point

Performance Benefits:

• Prevents bolt shear that can destroy the cylinder head and require costly replacement
