5.29 Ratio Differential Gear Package

The Nitro Gear & Axle GPBRONCO-529-EL is a comprehensive differential gear package engineered for 2021 and newer Ford Broncos equipped with M210 front and M220 rear differentials. This kit aims to restore optimal performance and fuel economy, particularly for Broncos fitted with larger, oversized tires that can cause the transmission to constantly hunt for the correct gear. By re-gearing the differentials to a 5.29 ratio, the engine's RPMs are brought back into the optimal power band, reducing strain on the drivetrain and improving overall efficiency and power delivery. This modification is beneficial for off-road enthusiasts with larger tires, increased vehicle weight, or for those seeking improved towing or acceleration performance even on stock vehicles. The package includes Nitro front and rear ring and pinion sets, along with corresponding Nitro Master Install Kits. These kits contain all necessary components for installation, including carrier and pinion bearings, pinion seal, crush sleeve, shims, gasket or silicone, and gear-marking compound. The Nitro Rings & Pinions are constructed from 8620 Steel Gear Forgings, feature precision machining, CNC triple-lapping, and are heat-treated and Rockwell hardness tested for durability. This gear package is explicitly designed for Ford Bronco models from 2021 and newer. A crucial fitment note specifies that it fits Bronco models with the *optional OEM front E-Locker only*. Installation requires approximately 7 quarts of Nitro Synthetic Plus Gear Lube. Nitro Gear & Axle provides a 2-year warranty against manufacturing defects on this product.
