What Customers Are Saying

Customers report significant frustration with replacement part compatibility, with many finding spools and trimmer heads do not fit their models despite universal labeling. Several note parts are unavailable in-store and online, forcing them to abandon the system entirely. Threading and design inconsistencies across generations render worn components irreplaceable. However, a minority report successful installations and praise improved spool design and durability. Those who succeeded often required third-party research and tools. Overall, incompatibility and parts scarcity overshadow positive experiences for most users.

Wrong threads

Would Not Recommend

The description states it's for the 80-volt trimmer; however, the threads are different from the original.

For OLDER 80v models only

Would Not Recommend

This is not universal in any way. It is only for older models of the 80V Kobalt string trimmer. It will not fit their latest 80V models or any other Kobalt string trimmers. Making that clear would save a lot of returns.

Not the fit

Would Not Recommend

Again as everyone else has already said. Not the right fit. It would be great if this part actually could be found so you don't have to completely buy a new one.

Easy to replace. Perfect fit. Use an allen wrench in the small hole to lock the motor and unscrew the old spool.

Do yourself a favor and purchase the Husqvarna T35 for your Kobalt 80volt trimmer. It fits perfectly. unscrew the old head, put on the large silver washer and screw on the T35 head and you're done. Stop looking for a part Kobalt refuses to make.

different thread

Would Not Recommend

this part looks like exactly what I needed, until I tried to screw it on. I took it to my local Lowe's thinking maybe there is a secret to it. I took wacker, old head, new head and they could not get it to mount. Thought there might be a burr in new one. No burr, so I will reorder but I think I will have the same problem. It is a well made part, just wish it worked.
