This kit is specifically designed for users seeking maximum horsepower who require the largest possible shaft size.\u003c\/strong\u003e \u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe billet half-shafts are manufactured from the highest grade 4340 chromoly currently available on the market. With an increased size and spline count, these shafts are capable of withstanding high torque and torsional stress, supporting over 1,500 BHP.\u003c\/p\u003e\n\u003cp\u003eThese kits are available in your choice of 5-bolt or 6-bolt (GT-R style) flange shafts.\u003c\/p\u003e\n\u003cp\u003eDeveloped using 4140 chromoly billet material, they are machined to withstand high loads to ensure that the left and right wheels remain locked at all times. These are ideal for drag or drift applications where equal torque must be applied to both wheels to ensure optimal acceleration capability.\u003c\/p\u003e\n\u003cp\u003eWeighing less than 5kg, this lightweight unit offers performance benefits by reducing rotational mass, resulting in improved acceleration and reduced drivetrain wear and tear.\u003c\/p\u003e\n\u003cp\u003eFollowing machining, the unit undergoes a nitriding process to increase durability.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cb\u003eWhat is Nitriding? \u003cbr\u003e\u003c\/b\u003e\u003cspan\u003eA heat treatment process that diffuses nitrogen into the surface of metal to create a case-hardened surface.
