Toyota's Tacoma 2RZ and RZ engines are capable of great power! Wiseco's K642 series piston gives you net 8.8:1 compression in the 2RZ and 8.25:1 compression in the 3RZ. We've designed it specifically for high boost applications.
You know the run-down of Wiseco's standard features and benefits. Well, these pistons have them all! It's made from a dedicated forging made in our Ohio forge shop for light weight and superior strength. We've designed it to give you maximum ring seal, compression, and control with a pressure seal groove and dedicated rings. Our ArmorGlide™ skirt coating reduces friction and wear. Brush deburred on the dome and valve beliefs to prevent detonation, Wiseco's Toyota Tacoma piston is the best choice for you.
It is offered in 95mm, 95.5mm, and 96mm bore sizes with a -10cc dome volume. All kits come complete with 1mm x 1.2mm x 2.8mm XX rings (stainless steel, gas nitride top ring; cast iron Napier hook second ring; and flex-vent oil ring with gas nitride scraper rails).
