What Rear shocks will fit a 400ex

[Knips178]

What rear shocks from other atv's will fit a 400ex? Will a 250r? I am having trouble finding a decent priced rear dual rate shock and wonder if another atv's rear shock will work.

[Pappy]

the only shock for a 400 is a 400 shock. the R shock wont work and niether will a z400.


why not just get the rear revalved :confused:

[Knips178]

What about cannondale rear shock, i know the fronts work.

[Pappy]

no a cannondale shock will not work and the fronts require a top bushing change not to mention the stroke is incorrect for a 400ex.

[Juggalo]

pappy is right, just do it right or don't do it at all

[simoniz]

What does your average rebuild cost for a 400 rear shock. And should I go with a elka rebuild kit etc.. Any suggestions on the rear susp..

[crap-banshee32]

i got the PEP rebuild rear...and it works just as good as my buddies true PEP rear..and for a fraction of the price

[EX4me]

Contact Santo Derisi about your rear shock. I'm getting ready to send him my rear shock off my 400 in Jan. Killer price to have everything done & setup for my weight & style of riding.

[Pappy]

ive had great success with both the quadshop and de risi. i havent used anyone else so i cant really say how others compare.


rear rebuild with elka parts and ssd conversions are like $350. im guessin that but it should be close.

de risi has a millenium kit but you would have to check his website for a price.

[Hotdog]

santo's quoted me 350 for re-valving,valving, new oil, seals, and nitrogen.

thats for my front ohlins and stock rear shock

for a true dual rate rear you need to have a CR500 link.

[Paul400ex2002]

or no link at all ;)

[Quadworks]

What does it take to run the CR500 link? Does it make a big difference? Whats the Pro's and Con's? Thanks

i never new that. I always figured it was still a true double rate cuz with pep zps its still tripple rates even though the top spring is just there to sag

PEP ZPS are a true tripple rate. They have 3 springs AND a spring for the ZPS. 4 Springs in total, so yes they are a true tripple rate. There rears however are single rate. They have 1 spring plus the zps spring. 2 springs in total. If you have a CR500 Link or no link then it would be dual rate with 2 springs plus a ZPS spring. 3 springs in total. Im sure you get the point. also this is for a 400ex i am not sure about other models.

Im not sure what to make of this comment. Are you saying different linkages wont effect how your shocks are set up? :confused: If so that couldnt be more wrong. Take for example ELKA. They have a new linkage which requires new springs for it to work. It even needs a full aftermarket rear no rebuilds i believe. Also the no link or cr500 link allows PEP to make a true dual rate rear instead of single rate. The stock 400ex linkage although very similar to a cr500 link can not handle the dual rate rear. If i interpreted your comment wrong im sorry.

I have a stock rear with a pep convsion. pep spring and valving. It is for sale!

If I put a CR500 link on my 400EX (with stock shock) what is it going to do for me? What is the purpose? Thanks

u cant just "put" a cr500 link on, u have to get a special swing arm, frame, and shock. i think for how much it costs its not even worth the extra perfrormance that a normal 400ex linkage gives

[Quadworks]

Hey thanks. I asked before but nobody would answer a simple question. I was just wondering why guys were doing this.

[Knips178]

What does it take to add direct link? Just a shock and swingarm that are setup for direct link? Does it give you more travel than the stock linkage?
Oh, and is it really worth rebuilding the stock shock versus just buying new (in other words is there realy that much of a difference between the stock shock setup and say a PEP rebuilt stock shock?)

Yes, there is a big difference between a rebuilt stock shock and an aftermarket shock.

Hey jeff catch up on your ready and you will know what people are talking about.

[Knips178]

Yes I mean no link. What all do you have to change to use No link? What does it give you over a normal linkage setup?
So your saying don't bother with rebuilding a stock rear shock from a 400ex, just buy an aftermarket one?

So your saying don't bother with rebuilding a stock rear shock from a 400ex, just buy an aftermarket one? You will need a swingarm, new shock, modified airbox and either an aftermarket frame or highly modified stock frame.
I found that a no-link setup doesn't kick to the side like linkage setups do and they work better in the small choppy stuff. Linkage seems to hook up better coming out of corners but I think the advantages of no-link are greater.

I'm not saying don't bother rebuilding a stock shock, I'm just saying its not as good as a full aftermarket rear shock.

[Knips178]

That helped alot, thanks for the info. Guess i'll be holding out to get new rear shock. So if anyone has a rear shock with ssd or zps for a 400ex, let me know.

[Paul400ex2002]

from what i've heard, the pep rebuilds are as good if not better than their complete new rear shocks.

[Knips178]

I find it hard to believe that a stock rear shock can be rebuilt to even being close to a true aftermarket rear. Even with spring, valving, and a refill....I figure there is some reason why Elka and Axis are selling rebuilt stock shocks to pro's
but, i could be wrong

and ps i'm still looking for a rear shock to buy

[Knips178]

check that, why they are NOT selling rebuilt stock shocks to pro's

[forum]

some of you people make me laugh/shake my head. OO yes! a stock shock with rebuild is much better then a fully built race preped billet aluminium custom built shock. give your head a shake. then come back and give info you didn't get out of a cracker jack box. Remeber if your having a tough time gettin info from people on this site. or just have a tough time believing it. CALL THE A SHOCK COMPANY. ... jeff@quadshop Is definatly someone to listen to... He is one of the few people that knows exactly what hes talking about. listen only to the right people.
