Product Details

This rear main seal set from Victor Reinz is made with a durable, multi-lip design. This advanced sealing technology helps prevent oil leaks from the crankshaft where it exits the engine block, a critical area for engine lubrication and performance. It's designed to fit a wide range of classic Cadillac and Chevrolet vehicles, ensuring you can get your project back on the road with confidence.

When you're rebuilding an engine or addressing persistent oil leaks from the back of the crankshaft, a well-made rear main seal is essential. This set uses materials chosen for their resistance to oil and heat, common conditions in this part of the engine. The multi-lip design offers an improved sealing surface compared to older, single-lip seals, helping to keep oil where it belongs and out of your driveway.

This seal set is a solid option for many Cadillac Commercial Chassis, DeVille, Eldorado, and Chevrolet models from the 1950s through the 1990s. Make sure to consult your vehicle's service manual for the proper installation procedure, as this job typically involves removing the transmission and oil pan.
