Good price and high quality!
This isolator relay is robust and has a higher amp load rating than the original relay. It was easy to install.

Ford starter solenoids are junk. Kept wedling the contacts shut despite new 4 gauge starter wire and 0 gauge grounds.
Swapped the solenoid with ine if these. No problems.
