Switzer Components is the developer of precision performance Honda TRX a-arm ball joint conversion kits. Our kits fit the most popular Honda sport ATV models, such as the TRX250X, TRX300EX, TRX300X, TRX400EX, TRX400X, TRX450R, and TRX450ER. Our Honda a-arm ball joint kits include a threaded steel insert and greaseable ball joint for each a-arm.
In order to install our Honda a-arm ball joint kit, it's required that you remove the factory ball joint assembly by cutting it off the a-arm. We include instructions for each Honda model on how to remove the factory ball joint assembly and weld in our steel threaded insert.
It's important to know which Honda model and designation you own. You'll find models with the designation of (A), (AN), or (AC), depending on model. Different models years can have different a-arm ball joint assemblies, which can be different sizes. We've inventoried each Honda model a-arm and ball joint assembly size.
If you have questions about your Honda TRX ATV a-arm size, please contact us before ordering.
