Testers

• Valve Spring Pressure Tester
• The original tool for checking valve seat pressure on an assembled engine!
• Built-in 300-lb reading scale
• Fits roller rockers on Small Block, Big Block, and 90° V6 Chevy; Ford 221-302, 351-400 SVO and Ford Windsor engines, and most other wedge-type engines
• Use with Moroso Stud Mount Valve Spring Compressors No. 62370 for the most accurate method of maintaining the valvetrain on a fully assembled engine

• Magnetize to the inside of your brake rotor, so you can always guarantee that you are measuring from a true point unlike others requiring you to measure from a bent wheel.
• Swiveling tape measures on the left side toe plate will span to the right side plate and attach to the magnets to hold your tape measure. Once the tape measures have been connected, just level your plates and make your adjustments.
• You will watch your adjustments be made in real time with no guess work!
• These work with 1"-4" Backspacing
