I decided to buy some scratchers after seeing the diference they made in my buddies sled. The RSI scratchers are almost twice as thick as his. They work great, and were very easy to install on my Apex MTN, I was even able to use some factory holes.
These are great ice scratchers for the money. Just remember to put them up when you leave the road or hard packed trail. I broke the tip off one side when I went through the woods. My bad.You also need to remember to put them before you back-up. Been there, done that too. Can't beat them for the price.
Bought the Race Shop scratchers three weeks ago. I ride an 09 RMK and have to spend more time then I'd like on trails. Installed these scratchers and dropped the coolant temp. 30 degrees while on the trails. Most of the time they're not needed, but when the trails are packed and iced these sure do the trick.
I've got these scratchers on all of my liquid cooled machines and they are a great help in keeping cool in icy conditions.
The negatives? Not much instruction on placement and you have to figure it out for yourself. (Take a look at a buddy's machine first if you can.# You will bend/break them... usually because you try and use reverse when they are in the down position. Boondockers can damage them off-trail. The key is to remember to put them up... but I think everyone forgets at some point.
But overall, if you heat up in icy conditions, and it seems all the newer machines do, these are a big help and protecting your engine #and hyfax) from a melt-down is the most important thing...
Product was easy to install on my 2002 Viper. I just had to remove the rear set of idlers to allow room for the scratchers, then used the larger diameter holes in the skid to mount the scratchers. I have not been able to try them yet, due to lack of snow, but hopefully they will help my overheating issues!
A great investment to cool your sled and keep your slides lubed. I will never have a sled without scratchers. These were easy to install and throw loads of snow into the track and slides. They dropped the temperature15-20 degrees.
