PROFORM’s New Professional Heavy-Duty Valve Spring Compressor should be called the Reinforcer. Featuring extra reinforced gussets, dual pins on the adjustable arm, and a reinforced compression-hold handle.
This adjustable spring compressor is designed for expert engine builders and cylinder head professionals. Designed to compress even the largest high-pressure valve springs (with the cylinder heads removed). Able to handle up to 1000lbs of pressure vs. the standard PROFORM P/N 66832 of 700lbs. For more precision, the spring cup includes two aluminum inserts that help square up the valve stem within the cup. This is a must have at the shop!
