Our new R&P gear sets are approved by Marlin and sold in limited ratios. They are designed like a Ninja to be Quiet and Effective! Equally as strong as any other ring and pinion gear set we've sold, they have now proven themselves through the many sets we've installed!

Looking to change your Ring & Pinion ratio & are unsure what to use? Factors include how much stop-and-go, flat highway, or mountain use your truck sees. In generally, 33" tires go well with 4.56:1 or 4.88:1, 35" tires go well with 4.88:1 or 5.29:1, and 37" tires or larger go well with 5.29:1. We do carry a 5.71:1 ratio for certain applications, however it is weak and is typically not recommended.

Curious how changing your Ring & Pinion ratio will affect your engine and truck's highway speeds? Use our below calculators to get an idea of the characteristics with your new R&P setup:
