Like the title says I have a KISS Coupler on my AXYS. Delivery was pretty fast but it came with no instructions so I had to find them on Zbros Racing website and print off myself.
Install:
Install is pretty easy except the instructions say to install at 2.2 inch measurement and I found using decimals with inches less than convenient if you don't have an appropriate caliper handy.
Secondly I had much reservations about cutting off the limit stop for the scissor arm. I knew if I ever want to return to stock it means a weld job or a new part.
Finally the coupler has bolts in each end and lock washers? This made no sense to me as the beauty of this device is that I can easily control the suspension transfer and change it when riding different terrain. I did not tighten the bolts all the way and used Red Loctite on the threads so I could still turn the aluminum shaft. This worked really well and I could turn it by hand but it never moved on its own.
Effectiveness:
I am very sold on the effectiveness and really enjoyed dialing to max. coupling for steep climbs and down 2 settings for trail riding in and out. If I did not dial it down on rough trail the suspension would fell harsh. This device really helped the AXYS stay in control when climbing through the tight trees.
Problems:
Unfortunately I don't think Zbroz tested this coupler enough before releasing it for the AXYS. The coupler I got has damaged my track and suspension. The scissor bent and cracked on both sides. I now have had to remove it, weld it and reinforce it with 1/2" angle iron from the scissor bolt to the limiter bolt. I talked to Nate at Zbroz Racing and he told me that the part I got was probably out of spec with the 2 nylon contact blocks too far apart. This wide spread of the blocks caused them only to contact the outside edges of the scissor arm, causing it to bend and break. Secondly included in the kit is a stainless steel cross shaft that goes in front of the lower scissor arm bracket as a new limit stop. As this cross bracket is installed so low in the rails, it has a lot of pressure on it when the scissor hits it. Mine is bending really bad. This cross shaft should sit much higher so there is less leverage on it when it contacts. The next disappointment is that the cut off limiter now has damaged my track. I did cut it off exactly as per the instructions and filed it down but on rear suspension compression, the track must smack down on it from above and it gouged the track and chewed off about 25-30% of the contacting drive cog (rubber nub).
Resolution:
Nate was very good at quickly sending out a new coupler kit but he did not seem to want to talk about the wrecked parts or damaged track. I have not installed it yet so i don't know if the new one will make any difference.,
Conclusion:
I guess when you buy aftermarket parts, it is buyer beware. Little aftermarket part companies just can't afford to to pay for damages beyond replacing their own products. Sledders are all guinea pigs for not only the sled manufacturers but also for the entire industry. That is the downside of owning the latest and greatest, by the time the bugs are worked out, you are riding something new.
