HKS Step 3 Stroker Kit RB26 2.8L

The HKS Step 3 Stroker Kit is a high-strength capacity upgrade designed for the RB26DETT engine, increasing displacement to 2.8 liters. This kit is engineered for serious enthusiasts seeking enhanced torque and power, capable of handling up to 1,200 horsepower while maintaining reliability under high tuning levels.

Featuring an 87.0mm bore and a 77.7mm stroke, the kit achieves a compression ratio of 8.7 (at t=1.2) and supports a maximum engine speed of 9,000 rpm. The kit includes a fully counterweighted billet crankshaft made from ion plasma treated nitrided steel for increased surface strength and toughness, along with high-strength I-beam connecting rods that offer 36% greater buckling strength and a longer shaft distance for durability under high torque conditions. The pistons are machined two-piece designs with nickel coating for anti-knock properties and incorporate cooling channels to manage heat effectively. This stroker kit is a direct fit for the RB26 engine block, optimized for high output and response.
