      Description

      Improve Off The Line Acceleration. Are you looking to get your 1986-1993 5.0L powered Mustang up off the line quicker? Then you should install a set of Richmond Excel 3.55 Ring and Pinion Gears. By upgrading to a steeper set of rear gears you will get your Pony into the power band faster for improved low end torque and faster acceleration. Richmond Excel 3.55 Ring and Pinion Gears are ideal for those Mustang owners that want quicker acceleration on the street, track or drag strip.

      Superior Quality. Richmond proudly manufactures their Ring and Pinion Gear Sets right here in the USA. Using state-of-the-art manufacturing processes and extensive quality control testing, Richmond produces a superior quality Ring and Pinion Gear Set at an excellent price. Richmond is so confident in the quality of their products that they back them with a 6 month, 50,000 mile no-nonsense warranty. 

      Recommended Upgrade. Please note that when changing the gear ratio of your Mustangs rear differential that the calibration of your speedometer will no longer be correct and will display the wrong speed. However, you can easily fix this annoying issue with a new Speedometer Gear (sold separately).

      Application. This 3.55 ratio Richmond Excel Ring and Pinion Gear set will fit all 1986 to 1993 V8 Mustangs equipped with an 8.8" solid axle rear end, including the GT, 5.0 LX, and SVT Cobra models. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

      Technical Note. Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations. You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.
