yfz shocks????

Just like they said. Your going to need the Diamond J Widening kit. You can find these off ebay. If you don't want to do that get some +3+1 a-arms like 89custom said, and they will bolt right up. As for the rear, your going to need to cut the shock a little. For something easier, go with a kfx400 or a 400ex rear shock. Very little fabrication to do. Hope this helps. And heres a link to tell you what you need for the 400ex rear shock installation.

dont get the diamond J kit off of ebay. you can get for $220.00 shipped from their site. usually with ebay you can "buy it now" now cheeper but, they charge you shipping and it ends up being more.

The rear shock mods are very very minor. search around the suspension part fo the forum, there are a bunch of different threads on the YFZ shock now.
