1999-2010 Ford F150 Motive 4.30 Rear End Gears (9.75 inch Rear Ends) | F9.75-430

Excellent Gears for Very Aggressive Street Trucks and Big Tires

Upgrading to 4.30 gears over stock drive ratios is a good choice for both street trucks that need improved acceleration and off the line performance over stock, as well as for F150s rocking 33" tires to get back performance and a more effective power band. While 4.30 gears have a pretty significant impact on fuel economy, the brutal amounts of acceleration on F150s with stock sized tires, street tires, or F150s built for the drag strip is often worth it. 4.30 gears are a great medium between 4.10 gears and even more aggressive (and borderline unstreetable) 4.56 gears. Each set of Motive 4.30 gears for the 1999 to 2010 F150s are built to fit perfectly and last your truck for thousands of miles.

High-Grade, Heavy-Duty CNC Machined Gear Steel

Motive's ring and pinion gears are each manufactured out of high-strength, high-quality materials and are designed for a great fit. The gears are CNC machined from extremely strong 8620 gear steel that is then heat-treated to ensure maximum rigidity and strength. Both the ring and pinion are built to near-OEM specs and will deliver low, factory-levels of noise in almost any application.

For Ford 9.75" Rear Ends Only: this set of gears will only fit Ford 9.75" rear ends found on 1999 to 2010 F150s. Both Motive and Stage 3 strongly recommend Motive's Master Install Kit during your gear installation.

Matching Front Gears Required: for 4WD F150s, a set of matching front 4.30 gears will be required for proper operation and drivetrain function.
