Description
When your tractor starts losing power, misfiring, or just doesn’t have the pull it used to, worn valve springs might be the culprit. These TISCO outer valve springs work alongside inner springs to keep your engine’s valves seating properly, ensuring good compression and the smooth power delivery you need when you’re pulling through tough conditions or running your loader hard.
What You’re Getting
- Durable outer valve springs designed to handle the demanding duty cycle of farm work
- Precision-engineered spring rate that matches OEM specifications for proper valve operation
- Quality steel construction that maintains proper tension through thousands of engine cycles
- Compatible with both intake and exhaust valve applications in supported engines
Built for Real Farm Work
These springs fit a wide range of tractors with Perkins diesel engines—the reliable workhorses that power everything from compact utility tractors to mid-size row crop machines. Whether you’re running a Massey Ferguson through hay season or an International through corn harvest, proper valve spring tension is what keeps your engine breathing right and delivering consistent power when you need it most.
Made to Last
Farm engines work hard in dusty, hot conditions, and valve springs are under constant stress opening and closing thousands of times per minute. These TISCO springs are manufactured from quality spring steel that resists fatigue and maintains proper tension even after extended operation. They’re built to handle the temperature swings and vibration that come with agricultural work.
Installation Notes
Valve spring replacement requires engine disassembly and is typically part of a broader engine rebuild or valve service. If you’re doing this work, it’s smart to replace both inner and outer springs as a set, along with checking valve stem seals and guide wear. A good valve job with fresh springs will restore compression and have your engine running like it’s supposed to.
