I’m looking to improve my suspension on my 2004 YFZ450 for XC Racing. Currently I’m running stock 04 a-arms with 09 yfz(carb) shocks, moose tie rod kit, burgard stem, etc on the front end. On the rear it is all stock 04 components, plus a skid plate of course. budget is tight but planing on running with the intermediate class or going all the way to the pro-class so if improvements to the quad can help me improve lap time by 45 seconds or so, i can be tire to tire with them.

On the front:
I’m looking to buy a set of Max Ground Clearance Long Travel XC A-Arms in the very near future. I’m going to try to use stock take off yfzr front shocks, from what I understand I can use these since the A-Arms will be long travel. Right? So the next question is what a-arms should I go with? I have been looking around and these are what I’ve found so far:
JD Performance Long Travel MGC Arms = $799
ASR-FX Pro Max XC A ARMS= $849
HOUSER MGC Long Travel Silicast A Arms= $874.99
LONESTAR DC-4 XC Long travel = $849
BOPP Big Clearance XC A Arms = $899
Walsh is out of my price range at $1500
Tiexeira Tech has some vicious looking ones that aren’t available yet, priced at $945 which is more than I expected to fork out.
Open to other brands also..
Or :
Buy a set of stock replacement uppers and have my shocks revalved.
GT Thunder will revalve and put the dual rate spring kit on for $395 not sure what other places charge.
JD Performance stock replacement uppers for $249
Ricky Stator replacement uppers for $219
And where to get the shocks revalved and resprung?
Liking the JD’s out of these two. Still open to other brands also..

On the rear:

I already plan to swap the rear end out and put a newer one on it. I already have the 08 swing arm and a complete take off yfzr rear end, swing arm back. I’ll use the carrier / axle assembly and yfzr brake system. So , I’m left trying to figure out what to do about the rear shock and linkages.
What I’m thinking is buy a newer rear shock and get it revalved and resprung, get a xc link, and the other linkage to have the right year model parts working together. Where to get shock worked and where to get a linkage from? GTTHUNDER, ASR-FX, OR OR OTHER BRAND? Elka linkage requires use of their shock.
Or get the 04/05 XC linkage and use my 04 linkage and shock with it and have the 04 shock worked?
GT Thunder will revalve, respring, and the linkage for the rear for $395, again not sure what others charge.
Or should I go a different route?
What skids do you like best for an 06 and up YFZ for XC racing? Any other products you recommend?
Thanks for your time!

thanks, i did look at these but wasn't sure about them because of the price and i would still have to get my regular shocks rebuilt to suit the arms and still only gain 1" of travel.. if i buy a complete set, i'd like to go long travel. see if the yfzr shocks would work and respring/revalve if needed. not enough money to invest in full aftermarket shocks yet. i figure if i go long travel arms, it will be easier to find better shocks later on to keep improving my set up...

have you tried a set of the atv four play arms, by chance?
thanks again.

We have found with years experience with working some of the top riders in the GNCC that long travel on the YFZ is not necessary for XC. With the proper shock you will acheive a very plush ride.
In fact the top riders in the GNCC are running our YFZ-X arms and those are basically a standard travel set up.
Also, Pro rider in the GNCC Brian Wolf is running our standard travel on his Honda's because he didn't like the feel on a long travel set up.

To answer you question....I don't ride XC so I would be the wrong person to ask. I just listen to our riders and we go from there.

I can put you in touch with a few companies that we have worked with that can re work your stock shocks.

ok, i see what your saying now. would i be better off sending my yfz shocks to be lengthened or going ahead and getting these yfzr shocks shortened? or would i be best to talk to one of the shock builders? which do you recommend for length changes on shocks?

thank you
