The product is a Clutch Slave Cylinder for rear-wheel drive vehicles, manufactured by LuK with the part number LSC265B. It is designed as part of the Clutch Hydraulics system and is a component of Clutch Parts & Kits in the Transmission & Drivetrain category.
Made my engine work again! I thought the clutch was going, but after I pulled everything, I discovered the slave cylinder has probably never been replaced. So I was happy with the one I bought, and it worked fine.
First one I have ever replaced, and I was happy with it.
