Product Description

The Revolution Gear & Axle T8IFS-488TR is a high-performance ring and pinion gear set engineered for Toyota vehicles equipped with the 8.0" IFS front axle. With a 4.88 numerical ratio and a thick reverse-cut ring gear tailored to 3.73-and-down carrier breaks, this upgrade offers enhanced torque multiplication, improved off-road traction, and robust drivetrain strength.

Manufactured from premium 8620 steel and precision heat-treated to OEM specifications, the T8IFS-488TR delivers durability and smooth operation under demanding conditions. Ideal for lifted trucks, heavier tires, or those seeking improved front axle performance, it supports enthusiasts who push their rigs. Installation should be performed by a qualified differential technician, with correct backlash and preload setup required.

While this gear set is compatible with a range of Toyota models - including Tacoma, 4Runner, and FJ Cruiser years listed above - full engine/trim/drivetrain/year breakdown through 2025 is unconfirmed at the time of listing. Buyers must verify fitment with their axle carrier, spline count, and vehicle setup before purchase.
