Description

When you’re rebuilding an International Harvester engine, the valve springs are working harder than you might think. These small but critical springs open and close your valves thousands of times per minute, handling the pressure and heat that comes with farm work. If you’re hearing valve noise or losing compression, worn valve springs are often the culprit – and since engine kits contain intake & exhaust valves, springs, this outer spring is what keeps everything working smoothly.

What You’re Getting

Outer valve spring designed specifically for International Harvester engines
TISCO quality construction that handles the stress of daily farm operation
Direct replacement part that works with your existing valve train components
Proper tension and materials to maintain valve timing under load

Built for Real Farm Work

This outer valve spring fits International Harvester engines and works alongside the inner valve spring to control valve operation. Whether you’re running a utility tractor for chores or a larger machine for field work, proper valve spring tension is what keeps your engine running right when you’re pulling heavy loads or working in dusty conditions.

Made to Last

Farm engines don’t get babied, and valve springs take a beating from constant cycling and engine heat. This TISCO spring is built with quality steel that maintains its tension over time, so you won’t be dealing with valve issues again next season.

Good to Know

Since the specs show 8 are used per engine, you’ll want to replace all the outer springs at once for even performance. When installing, check that your valve seats are clean and the springs seat properly – uneven installation can cause premature wear.
