Ford Performance Parts Axle Girdles

Ford Performance Parts axle girdles are a great way to strengthen the rear-end of your car. Made of lightweight aluminum, they incorporate load bolts that provide additional support for differential bearing caps. Because they reduce the amount of flex in your differential while under load, they significantly reduce bearing wear and chipped teeth on the ring and pinion. They provide increased ring and pinion gear life and are a definite must for all racing and high performance street cars. Additional information: * Available for a variety of applications, including some independent rear suspensions * Replaces OE rear cover * Covers with cooling fins and machined for differential cooler pickup and return fittings recommended for road racing or extended high-speed/high-temperature applications * Models equipped with differential coolers may require modifications * Check exterior clearance to chassis/suspension

ARB Differential Carrier Shim Installation Drivers

Insufficient carrier bearing pre-load can result in premature bearing failure and ring and pinion failure in all differentials, and possible oil/air leakage issues in an air locker differential. ARB differential carrier shim installation drivers are professional service tools for installing/servicing common shim pre-loaded differentials. Most common Salisbury-style axle assemblies require the pre-load shims to be tapped into place to achieve the required pre-load during set-up. Tapping shims into a tight space from a single point on the outside edge of the shim can cause damage to the shim, rendering it useless, resulting in extra cost and labor. ARB's shim drivers are comprised of six different sized steel profiles designed to evenly distribute the installation force around the outside edge of a differential shim as it is tapped into place, allowing thinner shims to be inserted into tighter places than would otherwise be possible.

Longfield Ring and Pinion Gears

Longfield ring and pinion gears are the very same that have won multiple championships in professional desert racing and competitive rock crawling circuits and have proven themselves on some of the most grueling off-road courses in the world. They offer superior strength, quiet operation, and durability through high-grade 8620 chromoly steel, precision 5-cut tooth profiling (increasing contact area), and Gleason CNC machining for high accuracy, smoother surfaces, and quieter operation, making them great for daily drivers. All 'standard finish' ring gears are black phosphate coated for wear resistance and corrosion protection. The black phosphate coating provides a microporous layer on the surface to hold lubricants to minimize friction between gear teeth, resulting in less wear during the initial break-in period and increases the overall life expectancy of the gears. Select the gears for your application. Key features and benefits: * Strength and durability—made from tough 8620 chromoly steel with a 5-cut tooth profile that distributes load better than standard gears, reducing stress and wear * Advanced tooth design utilizes a 5-cut process (instead of 2-cut) for a tapered tooth profile, increasing contact area and spreading load for less stress * Precision-cut using Gleason CNC machines for high accuracy, smoother surfaces, and quieter operation, making them great for daily drivers * Standard gears have a black phosphate coating to hold lubricant, reducing initial break-in wear and increasing longevity * Reduced wear and friction—features like black phosphate coating (standard) and REM ISF Super Finish (optional) minimize friction, especially during initial break in, extending gear and bearing life * Improved performance—helps restore power and acceleration lost with larger tires, allowing the engine to operate in a more efficient RPM range * Better value—Longfield goes directly to Tier 1 OEM manufacturers to have gears made to their exact specifications—by cutting out the middlemen, they can offer the highest quality gears at a competitive price

This process creates a mirror-smooth surface, drastically cutting friction, heat, and wear for improved performance, durability, and quieter operation, all while using strong 8620 chromoly steel and precision CNC machining. These are the very same type of components that have won multiple championships in professional desert racing and competitive rock crawling circuits and have proven themselves on some of the most grueling off-road courses in the world. Longfield ring and pinion gears are sold as a set. They are also available in kits that often come with high-quality Koyo bearings, new bolts, seals, shims, and essential solid pinion spacers (preventing loosening), and the necessary hardware for a comprehensive upgrade. Key benefits and features: * Superior strength—made from heat-treated 8620 chromoly tool steel with a 5-cut tooth profile for better load distribution * Quieter operation—high-precision Gleason CNC machining results in a more accurate, quieter-running gear set, ideal for daily drivers * No 'break-in' required—the ISF process eliminates the need for the typical break-in period, letting you hit the trails immediately after installation * Reduced friction and heat—the super-smooth, low-micro-roughness surface minimizes friction, leading to less heat buildup and improved efficiency * Enhanced durability and life—less friction means less wear, increasing the overall lifespan of the gears * Better torque transfer—the combination of accuracy and finish allows for more efficient torque transmission * Improved oil retention—the super-finished surface holds oil better, aiding lubrication * Enhanced performance—helps restore power and acceleration lost with larger tires, allowing the engine to operate in a more efficient RPM range * Better value—Longfield goes directly to Tier 1 OEM manufacturers to have gears made to their exact specifications—by cutting out the middlemen, they can offer the highest quality gears at a competitive price
