No, I bought the a-arms used, so they are setup for aftermarket shocks, not YFZ's. They are about a 1/2 inch longer. I put the bottom bolt through, then muscled the shock in. Not a big deal, wasn't hard.
The shocks are soooo much better then stock and the adjustability is unlimited. Compression, Rebound and Preload.
If you have any other questions, let me know.
