Looking to improve the stock suspension on my 400ex.

Do I need to replace the stock A-arms? If so, what is the advantage of replacing the stockers?

Looking at Works or Elka shocks for the front is one better than the other?

Should the rear shock be rebuilt or am I better off replacing it?

I just put a set of the works at steelers on my raptor 660r. They are a hell of a lot cheaper then th elka's. Cant really say their better but they are better then stock for sure. A +2 set of a-arms will give you more stability and better control of your quad.

Just pick up a set of Works AT steelers for the front and what a differance between stock. Now I'm looking to rebuild the rear shock.

I have had Works on several different quads over the years, and loved them! On my 400EX I currently have Steelers with cans on the front, and the Quadcross in back. This is the best setup quad I have ever ridden! It will bash huge dersert whoops all day, without even a hickup....

I think Works can rebuild/revalve your stock rear shock (?????).

I have called Works a few times and can not get anyone to return my calls, so I sent them an email. Hopefully they will write back.

If not I have contacted TCS and now waiting on a qoute to rebuild the rear shock. I am also going to call Hygear Suspension on Monday. I believe Hygear will rebuild the rear shock and the Works front shocks.
