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.\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePrevent 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes:\u003cbr\u003e\u003c\/strong\u003e1x Set of 7 Billet Steel Main Caps\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetails:\u003cbr\u003e\u003c\/strong\u003e- Manufactured in Australia from ultra-durable solid billet steel \u003cbr\u003e- Replaces fragile factory cast-iron main caps to prevent catastrophic breakage \u003cbr\u003e- Eliminates main cap walk and minimizes crankshaft tunnel distortion \u003cbr\u003e- Vital upgrade for high-horsepower, high-boost performance diesel engines\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003e\u003cspan style=\"text-decoration: underline;\"\u003eTechnical Specifications:\u003cbr\u003e\u003c\/span\u003e\u003c\/u\u003e\u003c\/strong\u003e- Supplier SKU: EMPNI131B \u003cbr\u003e- Brand: DPP (from Engine Australia) \u003cbr\u003e- Quantity: Set of 7 Caps \u003cbr\u003e- Material: High-Tensile Billet Steel \u003cbr\u003e- Machining Required: Mandatorily requires line-boring\/honing\u003c\/p\u003e","brand":"Engine Australia","offers":[{"title":"Default Title","offer_id":48918953001210,"sku":"EMPNI131B-TD42","price":1650.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/3979\/files\/ea3ecbe6-c074-404e-8c2c-78b5d1f2c97a.jpg?v=1779309474","url":"https:\/\/trundlesautomotive.co.nz\/products\/dpp-billet-steel-main-cap-set-to-suit-nissan-td42-engines","provider":"Trundles Automotive","version":"1.0","type":"link"}
