Husqvarna X-Force Chainsaw Bar

This bar is specifically designed for Husqvarna models 435(e), 440(e), 445(e), 450(e), 543XP, 545(MII), 550XP(MII), and the 450 Rancher. Before purchasing, always verify your saw's current bar length, pitch (0.325 inches), and gauge (0.050 inches) to ensure a perfect match.

The X-Force design channels oil more effectively along the bar, which significantly reduces friction and heat buildup. This not only makes your cuts smoother but also helps extend the lifespan of both your chain and the bar itself.

You can, provided your existing chain matches the bar's specifications exactly. It must have a 0.325-inch pitch, a 0.050-inch gauge, and exactly 66 drive links to function safely and correctly.

This bar is built for versatility. While it is lightweight enough for easy handling during brush clearing, its robust steel construction provides the stability and precision needed for felling trees and more demanding cutting tasks.

The drive link count must match your chainsaw's sprocket and the bar length perfectly to ensure the chain tension is correct. If the count is off, the chain will either be too tight to rotate or too loose to stay on the bar, both of which are dangerous.
