Having troubles with rear axles going bad on your Yamaha YXZ 1000R? It could be that the hard racing you have been doing has bent the rear frame allowing axles to be over extended. It hasn’t happened to you yet? Good! If you want to prevent this from happening and not spend hours fabricating a support bracket you might want to contact Weller Racing. Weller Racing has come up with their WR Edition rear frame bracket part number YXZ1024 to prevent the rear frame distortion before it happens.
The bracket is made of 4130 Chromoly and comes with a black powder coat finish. The bracket is designed to fit under the skid plate with no welding required. You will find that some trimming of the frame gussets are required, which a grinder can easily remove. Supplied with the kit are two 12.9 grade bolts to replace the existing lower swing arm mounting bolts. Installation requires reusing existing hardware.
We had a few hours of racing on our YXZ and think the frame may have been a little tweaked. That is because we had to struggle to get the final swing arm bolt installed. But with a little muscle and just a little slight coaxing with a hammer the install was complete.
Weller Racing shows photos on their website of an install on a bare frame so for those with a complete vehicle, this is how we did it.
