Description
Overview:
The Anti Vibration Spring for Stihl TS410 and TS420 is a genuine Stihl OEM component designed to isolate vibration between the engine unit and the handle frame on cut-off saws. Built from durable spring steel, it absorbs and dissipates vibration produced during cutting, helping the machine run smoother and making it more comfortable to use over long periods. Correct damping supports accurate cutting control and reduces stress on surrounding mounts and fasteners. This AV spring is a direct-fit replacement for worn or fatigued springs and is suitable for professional and DIY users maintaining Stihl disc cutters in construction, landscaping, and grounds maintenance. Genuine specification ensures reliable fit and performance without modification, restoring the saw's intended balance and handling.
Key Features:
- Genuine Stihl OEM part (4238 790 8304) for correct fit and function
- Spring-steel construction for strength, resilience, and long service life
- Helps reduce handle vibration for improved comfort and control
- Supports smoother operation and consistent cut quality under load
- Straightforward replacement using existing mounting points and hardware
- Aids in reducing wear on adjacent mounts and fasteners
- Manufactured to the proper stiffness for these models' vibration characteristics
- Suitable for daily site use where reliability and uptime matter
Typical Applications:
Used on Stihl cut-off saws to damp vibration during cutting of concrete, masonry, brick, and asphalt. Ideal for regular maintenance when vibration increases, the saw feels harsh, or visual inspection shows spring fatigue, corrosion, or deformation. Helps maintain operator comfort and steady handling on long shifts and tough materials in construction, utilities, hire fleets, and landscaping.
Also known as:
AV spring, anti-vibe spring, vibration damper spring, handle mount spring, vibration isolator spring, chassis-to-handle spring. These names refer to the same component that isolates the handle system from the engine unit to manage transmitted vibration during cutting.
