Description
Upgrade Your Rig’s Performance. So many factors influence your rig’s performance. Making upgrades to different parts and systems can change the entire way your ride sounds, feels, and functions. Replacing your old ring gear and pinion set with this Nitro Gear & Axle Dana 44 Ring Gear and Big Pinion Kit - 3.73 Gears, for example, will improve your street and off-road experience. This kit harnesses your rig’s Dana Spicer Model 44 to make the most of its strength and power.
Re-Gearing Unleashes Your Rig’s Potential. Your rig will benefit from this kit. It features a 3.73 ratio, which is thick. The ring gear measures a large 8.875 inches in diameter while the pinion shaft is 24 spline. The larger size delivers more power to your axle. 10 ring gear bolts are also included. Use this kit with a 1310 or 1350 series pinion yoke to unleash the most potential.
Constructed to be Highly Durable. You can rely on this upgrade kit because it is durably made. The parts are made out of strong, top-quality 8620 triple alloy steel. Precision machined and heat treated, the ring gear and pinion are long-lasting.
Installation Should be Completely Professionally. This kit is made for a direct fit but is still complex to install. It is recommended for professional installation as a result. Since this is an aftermarket upgrade, grinding on the housing will be necessary.
Warranty is Included. A two-year warranty covers this ring gear and pinion kit. See the manufacturer information for all of the details.
Application. This Nitro Gear & Axle Dana 44 Ring Gear and Big Pinion Kit - 3.73 Gears will fit your 1997 to 2006 Jeep Wrangler TJ.
