Nitto - 2.8 Wide Journal Stroker kit to suit RB25 / RB26 Block

NITTO's RB26DETT 2.8Ltr Wide Journal Stroker Kit consist of Nitto/CP pistons, available in a variety of sizes, cut from the Turbo HD forging, PVD Turbo ring set for the ultimate sealing capabilities and, of course, the CP 9310 wrist pins. Nitto 121.50mm I-beam in V2 configuration connecting rods are both available for the stroker kits and come with 7/16 ARP 2000 rod bolts as standard. The option to purchase Custom Age 625 rod bolts is also available on purchase. Finally, the Nitto RB26 2.8L 4340 wide connecting rod journal stroker crank is also included in the kit.

The most significant difference between this stroker kit and the standard connecting rod journal stroker kit is the extra width added to the connecting rod bearing journal. The journal has been widened by in excess of 20% from standard. The wider journal and bearing then enables the load to be dissipated over a larger area, increasing the life of the bearing and adding to the ability to produce more power. This eliminates the need for tuners to "tune to the bearing", allowing for more aggressive introduction of power without having to worry about the life of the bearing.

Not only does this benefit the life of the connecting rod bearing and journal on the crankshaft, it also benefits reliability via the connecting rod. In making the connecting rod bearing wider, the connecting rod itself also must be widened, and by virtue of adding more material to the big end journal of the connecting rod, increased power and reliability are among the benefits enjoyed.

Engine capacity is also increased from 2.5/2.6Ltr to 2.8Ltr which provides more power and torque. Much like our RB32 Wide Journal kits, these are a game changer for the RB26 market, employing a wider rod journal bearing. This wider rod journal bearing enables energy and force to be dissipated over a larger area than the standard journal size, enabling tuners to be more aggressive in their approach to power delivery to ultimately produce greater power. The connecting rod bearing has also been made larger in diameter to aid in greater strength. Additionally, we have upgraded the rod bolt size to a 7/16, making the rod wider, stronger and capable of even more reliable power and higher revs. See the fourth image for a comparison between the regular RB26 journal connecting rod against the Wide Journal connecting rod! The crankshaft itself also features a straight shot oiling system to ensure efficient oiling to the bearings.
