Product Details

The Yukon Gear & Axle ZG F9-620 is a USA Standard ring and pinion gear set engineered specifically for Ford 9-inch differentials with a 6.20:1 gear ratio. This deep gear ratio provides exceptional torque multiplication for rock crawling, heavy towing applications, and extreme off-road performance where maximum low-end power is essential.

Key Features:

  • 6.20:1 gear ratio for maximum torque multiplication and crawling ability
  • Designed and manufactured to exceed OEM specifications for durability
  • Compatible with Ford 9-inch rear axle assemblies
  • Precision-machined ring and pinion gears for proper gear tooth contact
  • Undergoes rigorous in-house quality testing including dimensional, material, and fitment evaluation
  • USA Standard Gear quality construction for reliable performance

This gear set is ideal for vehicles equipped with larger tire sizes or those requiring extreme gear reduction for off-road competition, rock crawling rigs, or heavy-duty towing applications. The 6.20 ratio restores lost power and drivability when running oversized tires while improving throttle response and engine braking capability.

This company is pretty good even when I found what I was looking for cheaper then some other websites

Great site and service!

Great service, prices, and timeliness! I will continue to shop at autoplicity!

Very easy and received a surprise 20% off shipping.

I deal with you before and always find some improvement in your business style and i really like it!Keep it good job! Super fast shipping and outstanding product by fantastic prize,lover then anywhere online.I would recommend this supplier to any car enth

easy web service

super easy checkout with amazon link! Let's you know if in stock or not, which is critical when ordering racing components.

I'm a stickler for finding the best prices on my purchases, while also making sure that the products I buy are legit and not some cheapo knock-offs.<br>I did my homework on the Clutch Stage 2 kit I wanted for my Spec V and found that Autoplicity had the best price anywhere, even a spot where I had 10% off came out to be more expensive.<br><br>I received my Clutch Stage 2 clutch kit pretty quickly (about 1 week) and everything was as expected.<br><br>Overall I would rate Autoplicity a perfect 10, although I did not have to contact their customer service or initiate a return, so the '10' would be on product selection, communication, website experience, and overall feeling that I got the best deal out there.<br><br>Thanks!

Great prices and great products. When it was received, the merchandise was correct and packed well. Thanks, will be ordering oil from this buyer from now on. (order #5647)

I had a coupon code for 2% off my total order, but the site wouldn't take it.

VERY GOOD

Convient and simple. I found that is was one of the best price on line.
