Strengthen your engine's cylinder architecture with the Supertech Block Guard, specifically engineered for the Nissan 350 VQ35DET. This kit includes both the left and right side guards to provide critical reinforcement for the factory open-deck block, bridging the gap between the cylinder walls and the outer block casting.

Designed for high-performance and forced induction builds, these guards effectively convert an open-deck block into a semi-closed deck. This significantly reduces cylinder sleeve walk and bore distortion under high boost or extreme RPM, protecting against head gasket failure and cracked bores. Each guard is CNC-machined for a precise press-fit and features integrated coolant passages to maintain efficient thermal management and prevent hotspots.

  • Fits Nissan 350 VQ35DET engines
  • Includes Left and Right side block guards
  • Precision CNC-machined from high-strength aluminum
  • Reinforces cylinder walls to prevent sleeve movement and cracking
  • Strategically placed coolant ports preserve factory cooling flow
  • Manufacturer Part Number: BG-VQ35-DET
