Description
When your vintage International Harvester tractor starts running rough or losing power, weak valve springs are often the culprit. These springs control how your intake valves open and close, and when they start to lose their tension after years of faithful service, your engine can’t breathe properly. This replacement spring restores proper valve operation and gets your IH running like it should.
What You’re Getting
- Proper spring tension that keeps valves seating correctly for good compression
- Quality construction that handles the constant cycling and engine heat
- Direct replacement for OEM part number 160907R1 – no modifications needed
- Set of 6 springs matches what your 4-cylinder engine needs for a complete intake valve refresh
Built for Real Farm Work
This spring fits International Harvester 100 series, 200 Series, Super A-1 Series, Super AV-1 Series, and Super C Series tractors with 4-cylinder gas engines. Whether you’re running cultivation equipment, hay tools, or just need a reliable machine for general farm chores, proper valve springs are critical for maintaining engine performance and fuel efficiency.
Made to Last
Farm engines work hard in dusty, hot conditions, and valve springs take a beating from constant compression cycles. This TISCO replacement spring is built to handle the demands of agricultural work, maintaining proper tension through temperature swings and vibration that would wear out cheaper alternatives.
Installation Notes
You’ll need 6 of these springs for a complete intake valve job on your 4-cylinder engine. While you’ve got the valve cover off, it’s a good time to check your valve guides and consider replacing exhaust valve springs too. A valve spring compressor makes the job much easier and safer.
