Genuine GMC Syclone Differential Seal

The Differential Seal from GMC Syclone will keep your vital gear oil where it belongs (inside the axle) while keeping the water and grit out. This helps to give the turbo truck cooler gears and smoother launches. Made to fit the bore snugly, the Differential Seal is built from advanced synthetic rubber to withstand the intense heat of hard boost and Syclone cornering. Fluoro elastomer is applied in later iterations, giving extra resistance to the hot 75W-90 fluid, while a track focused Differential Seal adds a latex coating that locks into the housing in the heat of takeoff. A spring loaded lip clamps the half shaft for oil retention and low drag. Drivers appreciate that instead of removing the complete axle, drivers can swap in a Differential Seal which cuts downtime and gets the pickup back on the road quickly. Every Syclone model from 1991 to 1993 is compatible, meaning one Differential Seal can protect street cruisers, garage queens, and track machines. The Differential Seal helps maintain the correct oil level needed by the limited slip unit which in turn supports the four-wheel anti-lock brakes and brings confidence when the weather is inclement. According to the owners, this Differential Seal lets the turbocharged powertrain send 65 percent of its torque rearward without any slip or overheating. This also helps in improving fuel economy and reducing gear whine. Also, it bolsters the GMC reputation from a reliability standpoint. Every genuine GMC Differential Seal passes the factory tests. So, whether the pickup truck is carving canyons or sitting in traffic, the seal performs mile after mile. Its toughness makes the GMC Syclone a legend. Long-time GMC enthusiasts recognize that a leaking seal can strip the Syclone of record setting acceleration in seconds. This proven part is a classic piece of GMC engineering, allowing any Syclone owner to unleash boost knowing the drivetrain is safe.
