Machined from 6061-T6 aluminum, the billet construction adds rigidity to the rear of the block, helping maintain proper sealing under high load, high RPM, and extreme horsepower conditions. This makes it an ideal upgrade for boosted, nitrous, and competition based builds where reliability is critical.\u003c\/p\u003e \u003cp\u003eEach kit includes all required components for installation, including an OE crankshaft seal, a high temperature O-ring, and stainless steel hardware. The O-ring material is resistant to methanol and ethanol fuels, eliminating the need for silicone sealant and reducing the risk of leaks caused by improper sealing practices. The billet design also improves durability and sealing consistency through repeated heat cycles.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003eCompatibility covers both sensor styles. \u003c\/p\u003e \u003cp\u003e2-wire VR (Gen1-2): 11-17GT, 15-20 GT350, 11-17 F-150\u003c\/p\u003e \u003cp\u003e3-wire Hall Effect (Gen 3): 18-26 GT, 18-20 F-150, 20-22 GT500\u003c\/p\u003e \u003cp\u003e3-wire Hall Effect (Gen 4): 21+ F-150\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eBPS part numbers:\u003c\/strong\u003e EN042-1117, EN042-18, EN042-21\u003c\/p\u003e \u003cp\u003eOrder against the \u003cstrong\u003ecrank sensor and reluctor the engine actually has\u003c\/strong\u003e, not the year on the registration — on a swap or a used long block those are often not the same answer.
