Manufactured from a unique steel alloy with a 168,000 PSI tensile strength (standard bars have a tensile rating of 130-140,000 PSI), this bar is able to flex under pressure then return to its original form after lifting. The high quality hard chrome finish protects the bar from rust, and the end caps are tightly fitted to protect the end bearings and clips against dirt and dust ingress.
