Key Features:

  • Precision-machined from high-quality steel alloys for maximum strength and durability
  • 4.11:1 gear ratio ideal for improved acceleration and pulling power
  • Engineered specifically for Ford 9-inch differentials
  • Manufactured using state-of-the-art CNC equipment for precise gear tooth contact
  • Heat-treated for superior wear resistance and extended service life
  • Tested to meet or exceed OEM specifications
  • Suitable for street, strip, off-road, and towing applications

Motive Gear ring and pinion sets are the result of extensive racing development and rigorous in-house engineering testing. Each gear set undergoes strict quality control procedures to ensure proper tooth contact patterns and quiet operation. Professional installation and proper setup with new bearings, seals, and gear oil are required for optimal performance and longevity.

I was very skeptical of ordering from Autoplicity, as I've never heard of them. They had everything I needed in stock and shipped very quickly, and for a much better price than my normal suppliers at Jegs and Summit Racing. I would recommend them to everyone...............Jeff

Super quick and easy ordering through Amazon!

Autoplicity had the best price for the product i was looking for. All items were shipped together and fit my truck.

The order was placed on a weekend (Order #30758 <br>Order Date: Saturday, September 15, 2012 Order Total: $31.73 <br>It was processed on the first business day. I couldn't ask for a quicker response.<br><br>Good joob all !!!<br>Marty Spellman

Fast shipping, product was excellent .

Very friendly customer service! They also shipped my radiator out very quickly. I will definetly be ordering from autoplicity again!

Ordered Thursday, shipped Monday... guess all in all we can't be disappointed. At least they had them in stock.

I build engines for Classic muscle cars and hot rods. Presently assembling chev. SB 383 cu/in. Went shopping for a Name Brand rotating assembly that was complete and ready to install.Shopped several other sites before finding "Autoplicity" Prices were GREAT (best I could find Anywhere), Shipping Very prompt, Shpg. charges Very reeasonable,I will Defenitely use them again!!!

Good prices. Good communication.
