On public forums you always have to consider the source. A bad review of an excellent tried and true product from one of the leading aftermarket manufacturers on the planet should throw up the automatic RED FLAG!
Properly setup and applicated the HOLZ Racing Products 09-10 front suspension kit with either Evol R or Evol X shocks is the single best option for all around performance.
No other product offers the combination of field tunability with correct geometry in a super strong yet light weight package for your Polaris IQ RAW or Ski Doo XP sled.
You can pull your 09-10 anti-sway bar in about five minutes to test and see if you like it with out. I've tried it a few full riding days without and did not enjoy the results. Thankfully its just as easy to reinstall!
Rob, you forgot the Z-bro's suspension package for both the IQ and XP chassis sleds. It is an excellent package for either sled and has the benefit of being cheaper than the comparable Holz package (XO shocks) and offering more ground clearnace than the Holz arms. Z bro's is standard with the triple rate spring package and a ride gurantee, both things to take into account when making a large purchase. Holz traditionally has had very good products, but others in the industry are passing them up in terms of performance, fit/finish and customer satisfaction.
I find it difficult to accept your words at face value as you have a fianancial interest in the health of Holz (their sponsorship of you) and are actively marketing their products. I also find it concerning that in any post that doesn't support the products that are your sponsors you call into question the validity of the users gripes and then their competency to have installed the product properly.
On my comments about fit and finish being better on the Z-bro's stuff vs. Holz. It stands. The 09 IQ arms we installed on a buddies sled had a few things we didn't like.
1. Powdercoat in the balljoint area, had to be sanded off to get the lower ball joint in properly.
2. Upper Heim joint connection is a threaded portion rather than the lock nut/jam nut like stock. The problem came for us when we measured the engaged portion of the threaded arm and found it to be less than stock.
3. Coarse adjusment of camber with the threaded portion, we lost much of the adjustability with the Holz than what was available stock.
4. Powdercoat doesn't match Anything that is a factory red accessory or stock decal on the sled which is an 07 RMK. It has more orange in it than he would have liked.
5. Ground clearance, the Holz arms protrude lower than the Z-bro's units, Bryan is worried he is going to damage one of the lower arms on a rock (which is why he bought the Holz units)
