Product Details

The Richmond Gear 4900451 Street Gear Ring and Pinion Set is engineered for GM 7.5" (7.625") 10-bolt differentials, delivering a 3.42:1 gear ratio for improved acceleration and performance. This precision-machined gear set is designed to provide reliable power transfer and durability for street-driven vehicles.

Key Specifications:

  • Application: GM 7.5" / 7.625" (10-bolt) rear differential
  • Gear Ratio: 3.42:1
  • Requires 3.23 and numerically higher ratio carrier
  • Compatible with GM 7.6" IFS (Independent Front Suspension) applications
  • Street Gear series construction for daily driving reliability

Important Installation Note: This gear set requires a carrier designed for 3.23 ratio and numerically higher gears. Verify your existing carrier compatibility before installation. Professional installation and proper setup with new bearings, seals, and gear oil is strongly recommended for optimal performance and longevity.

Richmond Gear ring and pinion sets are manufactured to strict tolerances and are a popular choice among automotive enthusiasts looking to optimize their vehicle's gear ratio for better throttle response and highway cruising efficiency.

Great transaction at a great price.

I am extremely satisfied with Autoplicity in terms of service, price, and shipping. I was shopping for a set of N-FAB step bars for my truck and was ready to purchase from Amazon when I decided to look around to see if there were better prices. I stumbled upon Autoplicity and was surprised to see their price on the bars. I checked with their online chat customer service to confirm that they would fit my truck and that the price was for a pair of the bars and not just one. (That's how low the price was!). I then placed my order and the bars arrived at my doorstep 3 days later! Autoplicity gets an A+ in my book and I'll definitely be coming back.
