NITRO CHROMOLY Birfields & Axles - Now available for Toyota applications!

Toyota Trucks & Landcruisers are well known for their strength & reliability all over the world.  Out of the box they feature some pretty great drivetrain, but they do have their limits.   The factory axles are 30 spline at the diff, but neck down to 27 spline at the birfield creating a failure point.  Additionally the factory Birfield joints are not built to withstand the added stress of larger tires and heavy offroad use. Nitro Gear & Axle has addressed this by offering a range of Heavy Duty Chromoly Birfield Joints & Axle Shafts.

-NITRO 30/30 Kits feature axles that have 30 splines at both ends, eliminating the factory neck-down.  Fully compatible with factory or aftermarket carriers, lockers, & hubs.

-High strength Chromoly Material featuring State of the art machining, heat-treating and polishing processes for uniformity and ultimate in stenght.

-Wide application range suiting most Toyota pickups, 4runners & Land Cruisers

Well as many know the Dana 44 axles found in the Jeep JK Rubicon are a new breed of dana 44. These new dana 44's feature a stronger design, with larger pinion diameter, etc. They also come with locking differentials. Now for the bad - many people have experienced problems with their factory lockers failing. Until now upgrading has not been really feasible, as the bearing sizes are odd and thus will not allow fitment of any aftermarket lockers. Also the axle center pins in the factory lockers are offset so different length shafts are required to run aftermarket lockers.

Nitro Gear & Axle now offers an assortment of Heavy Duty Cut-to-Length (CTL) rear axle shafts. The CTL axle shafts feature extra Long splines and can easily be cut to the desired length with a chop saw. This allows Nitro to use stronger rolled splines rather than cut splines and allows fewer part numbers to cover a wide range of OE and custom applications. This also makes it easier for Offroad, restoration, and Rod Shops to stock axles since they fit so many applications.

Nitro Gear & Axle now offers the industry's first 4.88 ratio Ring & Pinions to suit Chrysler's 8.25" differential.  The 8.25" differential has been used going back to the muscle car days, but is commonly found in Jeep Cherokee XJ & Dodge Dakota.  Until recently the durable 8.25" rear was limited to 4.56, which left Jeep XJ owners scrambling for a solution.  Now with 4.88 available the 8 1/4" is a true contender, offering more strength than a Dana 35, yet easier to source than the XJ Dana 44.

As with many c-clip style axles, the 4.88 does require a notched crosspin, or some minor clearancing to remove the crosspin.
