Crown Automotive Crankshaft Seals

Crown Automotive crankshaft seals are one of the most important parts of your car. These rear main seals are made from durable materials and are designed to handle extreme pressure and temperatures, as well as the caustic chemicals in your engine oil. They're located at either end of the crankshaft and allow it to spin freely and keep engine oil from escaping the engine block, as well as prevent contaminants and other debris from entering and causing damage to the mechanism. Because they are exposed to such abuse, main seals are subject to a lot of wear and tear, and replacement is the only cure when one malfunctions. Crown offers a large line of replacement seals, packing, and kits for your vehicle.

Trail-Gear Trail-Safe Transfer Case Output Seals

Trail-Gear Trail-Safe transfer case output seals are effective replacements. The lips are totally supported by a garter spring, applying constant force over the full 360 degree circumference. This prevents any deflection gaps and stops oil from bypassing the seal lip. The outer seal lip acts as a secondary seal and keeps debris and other contaminants away from the inner seal lip. The outer diameter of TG Trail-Safe seals are 100 percent rubber coated so that they form a complete static surface seal, resulting in zero leaks—and the outer flange prevents the seal from being pushed too far into the transfer case housing. Trail-Gear Trail-Safe T-case output seals also feature bi-directional double helix to keep the oil in the transfer case and water out, especially when the vehicle is on an incline.

Trail-Gear Pinion Seals

Trail-Gear pinion seals are direct replacements for your leaking seal. These Trail-Safe seals feature a lip totally supported by a garter spring applying constant force over the full 360 degree circumference. This prevents any deflection gaps and stops oil from bypassing the seal lip. The outer seal lip acts as a secondary seal and keeps debris and other contaminants away from the inner seal lip. The outside diameter is 100 percent coated with high-temperature polyacrylate rubber so that it forms a complete static surface seal resulting in zero leaks and maximum longevity. The outer flange prevents the seal from being pushed too far into the differential housing. This is by far the most effective pinion seal on the market, and will help you keep your favorite trails free of oil.
