The Nitto 4.0L kit retains the factory rotating assembly specifications and is a fantastic option. The kit includes custom Nitto/CP pistons available in both 92.5mm/+0.010” and 92.75mm/+0.020”, cut from CP’s Turbo HD forging in low silicon content 2618 material. The pistons are equipped with our custom crown specifications, PVD ring sets, full round skirt design, accumulator grooves and horizontal gas ports.

The connection between our crankshaft and piston is made possible by our I-beam connecting rod. Made from double melted forged billet 4340, this connecting rod features a stout I-beam design that has proven time and again to be capable of holding considerably high power without the added cost of the V2s. These connecting rods come with 7/16 ARP 2000 rod bolts as standard, with the option to upgrade to Custom Age 625+.

Completing the kit is the tested and proven 99.31mm stroke 4.0L crankshaft. This crankshaft has been purposely designed with strength and high power applications in mind. The crankshafts are an immaculate piece with precision manufactured knife edging to reduce weight and cut through crank case oil mist with ease. This enables the crankshaft to rev freely and easily. These kits are also available with aluminium connecting rods.
