Long Tracks - (over 600 CC):  Because more lugs are on the ground and this type of sled is usually not driven aggressively, you may use fewer per row. That is, if the cc chart would normally take you over 4 per row. If you ride 2-up or pull a cargo sled, we suggest you stay with the regular recommendation of Trail Grabbers per row per CC (as shown above).

*There are no absolutes in traction because everyone's needs and perceptions are different.

Add 96 more if you:

Losses are caused by too much stress.  The more aggressive you ride, the more grabbers you will need.  Avoid spinning the track - not only does this get you nowhere, but if the Trail Grabbers do hook-up hard, the rubber may stretch. This will open the holes and allow the Trail Grabbers to come out.

96 Trail Grabbers have been successfully used on a V-Max 600 that was ridden while sightseeing with occasional wide open throttle while lake crossings.  We recommend 192 Trail Grabbers for that machine, however some riders with more aggressive thumbs have used as many as 384 Trail Grabbers. You have to be realistic in your evaluation of your riding style.  If you do not have enough Trail Grabbers, you will over power them and you will experience losses, just as you would with standard studs.  If you see bulges in the back of the lugs, you are riding too hard for the number of Trail Grabbers.  Add 96 more, and if necessary relocate the bulging Trail Grabbers. 

This system was not intended to be cheap traction, but rather a reliable traction system without the major drawbacks of standard studs.  We suggest that you use 48 more Trail Grabbers than standard studs as a starter.  You can build upon that as necessary.

Some have used 144 regular studs in combination with 144 Trail Grabbers.  The studs will penetrate the same but when the track pulls the sled forward the Trail Grabbers will help.  This means the studs won't stress the cords as much because they won't tip as much.

A daring snowmobiler put 502 Trail Grabbers on his 1998 Thunder Cat 1000.  They weighed just over 2 1/2 lbs. and alternated 11 & 10 scratch lines, while 192 Woody's push-through weighed 14 lbs. with 4 scratch lines.  The Trail Grabbers worked just fine for the first 800 miles while he was breaking the sled in.  Once he got past the break in period and reached speeds over 110 mph, he started to experience losses.  The original Trail Grabbers were 1/2" in length so he replaced them with 5/8" and added 96 more.  The Trail Grabbers hooked up well enough to pull the skis off of the bare ice. 

After several passes, he checked the ice and found that the area where the Trail Grabbers came out was the stretch where he was traveling between 110 & 125 mph. If centrifugal force was the reason any came out, they all would have come out. What probably happened was that the Trail Grabbers hooked up hard while the track was spinning... while building up to higher speeds. The holes probably stretched open, minimizing the pressure on the threads, allowing them to come out a handful at a time.

Using Vise Grips and a hanging scale, it takes 70 lbs. of pull to remove a 1/2" Trail Grabber from a track.  Use a Vise Grips to back out a badly worn Trail Grabbers.  Pliers may help hold the lug from twisting excessively.
