I'm new to polaris, ??? about shocks.

[cb2honk]

Will the ski shocks off an 07 700 dragon fit on an 08 800 Dragon RMK? I like the adjustability of the 07 dragon shock vs. the non-adjustable Walker Evans.

 

[chunkysoup]

Yes they should be the same. i believe they r both 17" CTC.

 

[AndrettiDog]

Measure the CTC (center to center) with the shock off of the sled. Sounds like you are comparing a non RMK shock (which has longer a-arms) to an RMK shock. Seems that if the a-arms are longer the shock would be too. I would measure to be sure.

 

[cb2honk]

That is correct, the 07 is NON-rmk. I cant measure, because I dont have the sled yet. I'm going to pick it up next weekend.

 

[cb2honk]

The guy is telling me they mounted up fine, but he cant remember if he compressed them to get them to mount....and i know if he did that is bad. That's why I'm asking.

 

[HUNDO]

The Dragons and RMK's had the same 17" ctc measurement, just different brands/types of shocks

Sounds like Hundo has the down low on this, but I would not put on shocks that you have to compress or expand to fit. You would be taking away from your compression or rebound.

 

[cb2honk]

Thanks HUNDO. that is exactly what i needed to know.

Are you talking about an IQ-DRAGON or DRAGON-RMK??

Hundo is right the Dragon RMK and normal RMK's had the same C-2-C measurement at 17"

For this discussion I will refer to two different sleds
1) IQ-Dragon... 2007, 700CFi SHORT TRACK
2) Dragon RMK... 2007, 700CFi RMK

From your comment about "Adjustability" I assume you are talking about a 2007 Dragon IQ (short track)... With the Remote hose mounted adjustable clicker Walker Evans Needle shocks (coil spring shocks).

If that is the case... No... The IQ-Dragon shocks will not work well on your RMK.

The IQ-Dragon came with part number 7043206, Walker Evans coil-spring Needle shocks with hose mounted "clicker" remote compression-only adjustable front shocks.

7043206 has an extended length of 18.00" and collapsed length of 10.13"
The valving is very different and would not favor mountain riding... 704302 was also on the 2010 and 2011 Turbo IQ's

The front ride height will sit too high with the RMK length arms and you will experience higher steering effort and ski pressure ... the ball joints will wear out early and you will not experience the best quality handling that that level of shock has the potential to deliver.

There are many on the forums here that have mounted the longer IQ/SB/Assault length shocks on the RMK fronts... but I can guarantee that the performance is nothing compared to that same shock that had the correct length and valving for the RMK.

IMO... If you want adjustability buy the piggyback compression adjustable Walker Evans Front shocks from TCP at $650 for the pair, already valved for your particular sled and your personal riding style and weight... easier to mount as well. Those shocks are awesome.

In other brands, with compression adjustment you are talking about a pair of Z-broz X-1's at $1200 or a Fox EVOL-X at $1500.

From a previous post...

DO NOT run longer shock... it will add considerable ski pressure to the front and throw off the general balance of the sled. I have helped people with their sleds that have installed longer Floats etc from an IQR and got the fronts back to where they need to be... night and day difference.

You did not say what model year assault you have???

Raising the front end will also wear out the rod ends as you approach/exceed maximum angles for the ball joints/rod ends/

....

If you get a set of used shocks... absolutely make sure that they were built/valved for the exact sled you have... just getting the length correct is not enough. Plus... being a used shock...you will still need to get them serviced, plus they will still not be valved just for you.

Quote:
I don't really understand how a longer shock will put more ski pressure down. If one shock is 12" and another is 13" and they are valved the same, shouldn't the pressure be exactly the same?

I am wanting more ski pressure. I am not saying I don't agree with you but I just don't understand the logic on longer = more pressure.

A longer shock raises the front end... doing so will unweight the front of the skid...similar concept but to a larger degree than using a softer front track shock (fts) spring or sucking the limiter straps up. This places a larger percentage of the sleds weight on the skis.... that equates to higher ski pressure and more steering effort.

Think of it this way.... picture a profile shot of the sled... draw a line down the bottom of the hyfax and extend it... notice its relationship to the ground... now lift the front of the sled... what happens to that line?.... Of course this is simple description that does not take into account suspension compensation and increased pre load on the rear track shock.

The "balance" of the new sleds is pretty sensitive. Ride height on the front is CRUCIAL to good handling characteristics.

Change one thing and you change the entire "system".

Not 'text book wrenching' but actual field testing results.


Also, don't confuse ski pressure with ski lift... 2 different things... If you are lifting on steep climbs... longer front shocks or higher rate springs will not improve the situation... that "lifting" is a rear suspension issue.

 

[HUNDO]

MH, you should write tech books on this stuff...you'd make a fortune. I didn't even know there was an IQ Dragon 700 short track

 

[cb2honk]

I think there may be some confusion, so i will try to be more clear.

I just talked to the guy with the sled, It is a 08 DRAGON RMK 800 w/09 A-ARMS

The shocks are from a "2007 Dragon IQ 700 (short track)... With the Remote hose mounted adjustable clicker Walker Evans Needle shocks (coil spring shocks)."

Will this work?

 

[tdblakes]

No. You'll need longer A-arms or shorter shocks.

 

[mountainhorse]

That is what I thought you were referring to...

Simple answer ... NO. (see above)

TCP => Tri City Performance... They will set you up with what you need and custom valve them...Ask for Max 801-298-8081

These are the same model of shock that was on the 2010 Assaults BUT... valved for your needs, the correct length and upgraded to dual-rate springs.


If you want a non-adjustable shock for about $75 less... Carl's Cycles is great with the Fox zero pros.(or anything fox For that matter)

If you are not on a budget... The Z-Broz X-1 shocks are TOP notch. I think $1200 this year.

I think there may be some confusion, so i will try to be more clear.

[MNIQR]

MH always a pleasure to read your banter.

Lets not forget guys that these short track shocks he has can be slugged down to the correct extended length. Not sure if compressed will be right but it may be an option as well.

 

[mountainhorse]

MN...Yep... they can have internal spacers ("slugs") put in... But that is a HUGE spacer @ 1".

The compressed length at 10.31" is ok... not sure if you will have enough room to adjust the preload to the right setting (enough threads on the body??)

The cost of that, a service, revalving, boxing, shipping both ways... This can, most of the time, change a "deal" into costing more than the right shock in the first place, IMO.

I am mounting these exact shocks from TCP on my 07 RMK Dragon. You will need to make a slight modification on the older style fender plastic for the clicker reserviour to fit. They fit right up on my 2010 RMK with the new fender plastic, but require a slight amount of plastic removal to clear on the older style. I haven't tried yet, but you may be able to heat and bend the fender area out a little to make them fit also.
