Fitment Notes

• Set of 16 covers all exhaust valve guide positions for one complete VK56 V8 engine (16 exhaust guides total across both cylinder banks).
• Covers both VK56DE (port injection, 2004-2015) and VK56VD (direct injection / VVEL, 2010-present) variants - verify guide boss diameter and stem clearance with your specific engine build specs before installation.
• Traditional smooth-style guide (no stopper) - seating depth must be measured and verified during installation.
• Standard OD sizing; light honing of the guide boss may be required depending on head condition and target clearance specification.
• Oversized OD options (+0.001" and +0.003") are available individually for heads requiring bore service.

Features

• Manufactured from true C67410 Manganese Bronze for superior lubricity, heat dissipation, and long-term wear resistance over OEM cast iron guides.
• CNC-turned on dedicated precision turning centers to maintain the tightest OD-to-ID concentricity tolerances in the aftermarket.
• Traditional smooth profile for direct compatibility with standard VK56 head configurations without modification.
• True-to-size OD minimizes guide boss honing on heads that don't require bore service, reducing overall installation time.
• Set of 16 provides a complete exhaust guide set for both cylinder banks in a single purchase.
• Compatible with GSC VK56 exhaust valves, valve stem seals, and spring kits for a complete matched valvetrain rebuild.

Product Description

The GSC Power Division 3047-16 is a complete set of sixteen traditional smooth-style Manganese Bronze exhaust valve guides for the Nissan VK56 5.6L V8 engine, covering both the VK56DE (port injection) and VK56VD (direct injection / VVEL) variants used across the Titan, Armada, Patrol, QX56, QX80, Pathfinder, and NV commercial vans. The VK56's 32-valve DOHC V8 layout requires 16 exhaust guides total across both cylinder banks, so this single set covers the complete exhaust side for one engine. Made from true C67410 Manganese Bronze, these guides deliver improved lubricity, better thermal conductivity, and significantly longer wear life compared to OEM cast iron - particularly valuable in high-displacement engines where guide wear directly impacts long-term seal integrity and combustion efficiency.

Precision CNC-turned to the tightest OD-to-ID concentricity tolerances available in the aftermarket, the 3047-16 requires minimal honing on undamaged guide bosses and installs directly into standard VK56 head configurations. The smooth profile requires the installer to manually measure and verify seating depth during installation - no stopper collar is included. For heads requiring bore service, +0.001" and +0.003" oversized individual guides are available separately.

A straightforward upgrade for any VK56 head rebuild - whether refreshing a high-mileage Titan or building a performance VK56 for track or drag applications - the 3047-16 pairs directly with GSC VK56 exhaust valves and valve stem seals for a properly matched exhaust-side valvetrain.
