DPP Billet Steel Main Cap Set to suit Nissan TD42 Engines

DPP Billet Steel Main Cap Set to suit Nissan TD42 Engines

Please note: This billet steel main cap set is a high-performance competition-grade component. Installing these caps requires advanced automotive machining; your engine block MUST be line-bored and line-honed after fitting to ensure absolute roundness and perfect crankshaft tunnel alignment. These caps should strictly be installed using high-tensile heavy-duty main studs or high-strength fasteners (such as ARP). Failure to line-bore the block will cause immediate engine seizure upon startup.

Prevent bottom-end failure and eliminate main cap flex under high load with this premium race-spec upgrade. Engineered and manufactured in Australia, the EMPNI131B kit replaces the fragile factory cast-iron main caps with high-tensile CNC-machined billet steel units. Designed explicitly for performance diesel builds subjected to extreme boost, high torque, and endurance demands, these caps offer an immense increase in structural rigidity over OEM components. By dramatically reducing cap movement ("cap walk"), they safeguard your main bearings from uneven wear and protect the crankshaft from destructive harmonics. Each cap is precisely profiled for optimal weight and clamping force distribution, making this set the definitive choice for professional engine builders pushing their power limits.
