Description

A 3.55 gear ratio differential ring and pinion kit for the 9.75-inch rear axle. If your F-150 is two-wheel drive, you can change your rear gears without any driveline issues. However, if your F-150 is a four-wheel-drive model, you will need to change both the front and rear gear ratios to match. Failure to do so will cause severe damage to both the transfer case and transmission. Installation requires mechanical expertise or professional installation and takes approximately 4 hours.
