Available Options:

• OE Replacement Bolts – High-quality OEM‑spec fasteners for factory-style rebuilds and stock power levels.
• Heavy Duty Upgrade (MR16DDT Bolt) – Popular performance choice using the MR16DDT‑spec bolt for higher and more consistent clamping under heat, load, and RPM.

Why choose the Heavy Duty MR16DDT bolts over OE?

Higher and more stable clamping load: The MR16DDT fastener profile and material spec deliver improved head‑to‑block clamp consistency, reducing the chance of head lift when cylinder pressures rise (high RPM, track abuse, or forced induction).

Important: Nissan VQ35HR & VQ37VHR head bolts are torque‑to‑yield and must be installed following the factory torque and angle specifications. Always replace head bolts during installation. Professional installation is strongly recommended.
