Here are some pics...'05 monoshock and 1.25" Ripsaw in '02 Viper. I used the RX-1 rear mounting brackets and the mid pro-action brackets(with some modification) for the front bolts. Just waiting on my cable boot and protector and I will be ready for the season.

When Gorman lets me ride the Apex GT. Talked to him last night, he is making the call today.
 
Thats awesome. I can't wait for you to tell us how it rides ? What kind of coin would it take to put one of these in ?
 
I have seen them for sale from anywhere from $750 to $1300 for a complete suspension. Bender has a kit that is $1000 w/ a different shock that doesnt use the adjuster, but you reuse your rails and idler wheels. I have about $60 in brackets, rivets, and bolts.
I took me close to 10 hours from start to finish, but I replaced the track at the same time. You need to cut or drill out about 1 million rivets. the stock rear bracets were in the way so they had to go. the right mid bracket was in the way of the adjuster, so i took them both out and used them for the front mounting point.
 
It will work on any '97 and newer Pro- Action chassis. I spent a fair amount of time measuring '05 Rx-1's and '06 Apex's to make sure my measurements would work.

The Deltabox sleds have the hole for the front bolt of the Pro-Action skid becasue the Pro-Mountain and Pro Active use those front mounting holes. So I measured from those holes to the front bolt of the Mono-shock(horizontal and vertical). Make sure the sled is level or your numbers will be off. Then measure from the front Mono-shock bolt to the two rear Mono-shock mounting bracket bolts(horizontal and vertical).

I then had to use the front to back Mono-shock bolt distances as a radius to rotate it around the front bolt and get the rear bolts down in the tunnel so that the track would clear the tunnel protectors.

If I did it again I would use the front mounting bracket from the proaction for the front mount on the Monoshock with a large plate on the outside. I had to cut the mid-mount bracket a fair amount so that the suspension hole would line up with the mounting bracket hole. I moved the front bolt hole towards the engine about .5" so that the rear bolt hole would lineup where the old proaction rear bolt hole is. Because the monoshock skid is about .875" narrower than the pro-action I used the '05 RX-1 rear mounting brackets and opened up the rear Proaction mounting hole so the bolt could pass through.
 
ever get any riding in on this setup? want to maybe get a bender setup over the summer. see how it goes though. may want an 07. $$$ will decide it lol!
 
Its out of a vector,the vector definatly rides better than the old pro action.He's putting in a mono,so i figure I'll take that off his hands.
 
I have about 300 miles on the mono so far. It is way better than to pro-action. I still have some tweaking to do. It actually absorbs bumps instead of bouncing over them. If we ever get some snow i will be able to check out its big bump ride. It takes the normal sized mogals really good. I want to see how it does on the Powley Rd in the real big bumps. I rode an Apex GT and my Viper on the same trails and the GT did ride a little better, but it wasnt a huge difference..I am keeping my Viper for several more years. I got 4500 on it now and I plan to hit 10,000 with it.
 
The sled handles exactly the same as with the pro-action. I have some darting and ski lift to fix, but I had that with the pro-action as well. The transfer is much better. I went from the stock .92 track with the pro-action to the mono with the ripsaw. with the transfer set in the middle on the mono i will hook some nasty wheelies from a stop in crusty or deeper wet snow. You could really feel it tranfser at any speed. Let off at 90 and you feel it unload. I set the transfer for a less than half becasue i was pulling wheelies off hills at 50mph or so.
 
I recently installed a cat skid in my 04 Viper S, definitly worth doing! Anything but a pro-action! I can take studders sitting down and almost completly eliminated kick-back over the large G-bumps!

I found the same results, the Mono in the Viper S is the $hit, transfers all the time, and the sled is faster because of it. I opted for the Ohlin so I didn't have to drill the hole in the tunnel and I used the stock Apex brackets in the front, you end up using the stock rear holes.

What about the ride in the bumps compared to the proaction?
 
bumps are night and day normal trail bumps don't exist, small stutter bumps aren't there any more
