For the mechanics and DIY enthusiasts working with gear pullers, these Kukko replacement arms are exactly what you need when your original arms wear out or you need extras. Specifically designed to work with Kukko gear puller models 880100 and 880130, these arms feature some really smart engineering. The glide and fix technology means the cross-bar and sliding parts have optimized geometry, making it super easy to reposition everything during use. Then there's the self-lock technology - when you tighten the fixing screws, the hooks center themselves and grip whatever part you're working on firmly, preventing any slipping or movement that could damage your workpiece. What's really clever is how versatile these arms are - by simply turning the hooks, you can use your gear puller as both an outer and inner bearing puller. That means you're basically getting two tools in one! The build quality is exactly what you'd expect from Kukko - durable, precise, and built to handle tough jobs. Whether you're working on automotive repairs, machinery maintenance, or any project that requires removing gears, bearings, or pulleys, having reliable replacement arms on hand means you can keep working without downtime. They install easily onto your existing Kukko puller frame, so you're back in business quickly. For professional mechanics, these are essential backups to have in your toolbox. For serious DIYers, they extend the life and capability of your puller setup. The design really shows how much thought went into making gear pulling safer, more secure, and more efficient. If your current puller arms are showing wear or you just want to have spares ready, these Kukko replacement arms deliver the quality and performance you need.
