The 3RZ Steel Flywheel is intended for use on vehicles with large tires. This flywheel weighs 35 lbs. The increase in flywheel weight causes the engine to remain higher in the power band when shifting. This decreases the amount of performance lost with larger wheel and tire combinations.
It is great for towing or hauling heavy loads and is ideal for double or lower geared transfer cases. The 3RZ Steel Flywheel is CNC machined out of solid billet steel with a steel flywheel ring gear welded on for maximum durability.
