The Ultimate Solution to Factory Head Bolt Failure

The M156 AMG engine is notorious for factory head bolt failure, but VRP H-13 Head Studs for the M156 provides a reliable solution. The factory head bolts often suffer from a critical design flaw. They are installed as “torque to yield,” meaning they stretch permanently when tightened. This stretching compromises their strength, leading to common snapping. When the head bolts snap, the head can lift, mixing oil, coolant, and air. This can cause severe damage to the engine internals.

To address this issue, we’ve developed the VRP H-13 Head Studs for the M156. Our head studs are a direct replacement for the problematic factory bolts. Unlike most aftermarket head studs made of mild steel, our VRP H-13 Head Studs are crafted from premium H-13 steel. This material is renowned for its strength and hardness, making our head studs the toughest on the market.

Key features:

• Superior Strength: Made from H-13 steel, offering unmatched durability.
• Reliable Performance: Prevents head bolt snapping and ensures a secure fit.
• Direct Replacement: Fits perfectly in place of factory head bolts.
