Will upper and lower PRO arms fit an IQ. Seems they will. I did a search and did see any matching results
2013 PRO A-Arms

The bushings on the bulkhead end are different I.D.... but the od is the same... use the IQ bushings...
The Ball joint on the lower has a hair larger bolt hole in it... 10mm compared to 3/8".
You can use the IQ ball joint in the PRO lower (both have same O.D) OR ... you can Drill the three IQ spindle holes for the upper and lower ball joint to 10mm.
The upper ball joint where it threads into the a-arm has a different thread on it...re-use the PRO Upper bushing and drill out the hole in the IQ spindle to the 10mm size of the pro Ball joint mounting bolt.. You could use the IQ upper ball joint spindle bolt from the IQ but there would be a hair of play that might oval-ize the hole in the spindle over time.

And the shock length difference between '13 arms and IQ arms is 16.6" for the '13 and 17.25" for the IQ arms. You can use the Pro shocks on the IQ's.
Good catch... missed that they are 2013 arms.
The difference is about .9" 2011/12 to 13/14/15 on shock length.
So the diff would need to be the same on the IQ...
The shock length on an IQ is 17.00"... so the shock length on an IQ running the 2013 lowers would need to be .9" less, or 16.10 (about .5" shorter than a 2013 PRO RMK Shock).
You would also need to bore/tap out the lower shock mounting bolt hole in the 3013 PRO RMK arm to 3/8" and use a socket head bolt to fit the bushing on the IQ shock OR get bushings to reduce the ID of the shock-eye bushing to 8mm (5/16") from the 3/8" size
I am assuming you are talking about the 2013 Bonded A-arms from a PRO RMK and not the welded arms from a Standard RMK.... If they are the welded 2013's... then no shock change is necessary.

I used Pro shocks on my IQ Dragon, it handled like garbage but the shocks fit with no bushing adjustment. The difference in the hole size is virtually nothing.
But a 10mm bolt/stud will not fit in a 3/8" hole.
The lower-eye mount bolts in the 2013 PRO RMK arms are 8mm. The lower eye in an IQ has a larger 3/8" hole.

10 mm and 3/8 are close to each other and there was no problem with it going in. The tolerance is large enough to make it work.
10mm = 3/8 = 13/32 = 0.39"
I've gotten away with putting a 1/2" socket on a 13mm nut.
I understand they are close...
I just tried to put the 10mm bolt into the top hole of a dragon spindle... no luck... It is a hair to small.
Ball joint... lower... Dragon... also no go with the 10MM bolt.
Not surprising that a Dragon 3/8" shock mounting bolt would fit into a 10mm bore as it is bigger... the other way around... no go.
You can't slide a good quality 3/8" wrench on a 10mm headed bolt.
I'm not trying to be a smartazz MileHigh... I've just tried it before.
Easy to drill out though.

You are totally correct on the 3/8" vs. the 10mm bolt. A 10mm bolt does NOT fit in the 3/8" upper chassis mount on an IQ!! And I would NOT recommend using a 3/8" bolt in the hole sized for a 10mm metric bolt.
As for the shock length of an IQ front shock.....I stand by my original dimension of 17.25" CTC. Just measured 2 sets.
Now for this scenario....
If the OP uses a set of '13 shocks with the '13 arms, he will be able to use an 8mm bolt for the lower bolt and drill out the upper mount on the IQ chassis to 10mm and use a 10mm bolt. I've done this multiple times when using '11-'12 Pro RMK shocks on IQ's but this was with stock IQ and/or '11-'12 a-arms.
They work very well on IQ's.
If the OP were to try an use any other shock other than a '13 or '14 with the '13 arms, then there will be an issue as all of the earlier shocks run 10mm bolts in the upper AND lower holes for '11-'12 Pro's and 3/8" for IQ shocks.
The '13 and up lower a-arm shock mount is only 8mm. There is not enough material to drill and tap to a 10mm bolt. No way, not possible.
Not to mention that a height issue will occur as the lower mount of the '13 arm was relocated to accommodate the shorter shock '13 and up shock. 16.6" CTC.
The other big thing in this scenario is the sway bar mount. If the OP's sled (and /or sway bar assy.) is earlier than the 09-10 IQ and is perhaps an 06-08, then the sway bar will not bolt up to these arms. If it is an 09-10, then the sway bar will mount no problem.
If the OP does in fact have a set of '13 or '14 front shocks and has an 09-10 sway bar, then this will work just fine.
