Product Details

The Richmond Gear 4900461 Street Gear Ring and Pinion Set delivers reliable performance for GM 7.5" (7.625") 10-bolt rear differentials. This precision-engineered gear set features a 3.73:1 gear ratio, providing an excellent balance of acceleration and fuel economy for street-driven vehicles.

Key Specifications:

  • Gear ratio: 3.73:1
  • Application: GM 7.5" / 7.625" (10-bolt) rear differential
  • Compatible with GM 7.6" Independent Front Suspension (IFS) applications
  • Requires a 3.23 and numerically higher ratio carrier
  • Street Gear series for daily driving durability

Richmond Gear ring and pinion sets are manufactured to strict OEM tolerances using high-quality steel alloys for strength and longevility. This gear set is ideal for trucks, SUVs, and muscle cars looking to improve off-the-line acceleration while maintaining highway drivability. Professional installation and proper setup with new bearings, seals, and gear oil is recommended for optimal performance and lifespan.

Important: Verify your differential carrier casting before ordering. This gear set requires a carrier designed for 3.23 ratio and higher (numerically higher gears). Not compatible with 2.73-3.08 ratio carriers.

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

Pleased so far

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 .

Amazing !! FAST SHIPPING and GREAT PRICES !! I couldn't ask for better !! I will definitely shop with Autoplicity again !!

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34

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.

Great prices. They sent what I ordered and it was what I expected. I would shop with them again.
