im putting a viper mountain 144 stock skid into my 02 srx. ive got it mounted using the dimensions taken from the original sled. the problem im having is when i compress the rear of the sled the suspension lowers about 2.5" inches then the tranfer rods bottom out and the suspension stops dead there then returns up. im thinking that it has to have more travel than that. i cant see what i did wrong maybe spmeone can point something out im missing. the front 2 mounts of the skid to the tunnel are the exact distance from each other as they were on the original sled (13.75"). the linkage on the front end of the rear shock is just about straight up and down. maybe this is how it should be but it doesnt seem right having that little travel and when it bottoms out is because the rods keep it from compressing any further.
the front of the skid seems fine its the rear of the skid that is the problem.
hers what the skid looks like. help please

I once had the same problem when i had my pro-action skid.If I remember right i think it was something simple like the scissor action when the suspension compresses was going the wrong way.this was right near the rear of the track right behind the transfer rods.Had me scratching my head for a while.LOL.Ihope this helps!!

These things are funky thats for shure!The sled is setting high in the rear and low at the front.Maybie more than a stock mm?I would try undueing the bottom bolts on the transfer rods that are holding them to the rails.If that helps modify the top washer so it will travel more and not bottom out so qwick.That should work and will be better in the deep.
You need to also make sure the rear holes are EXACTLY the same distance from the center holes as they where stock. If not, it will do just what you are saying it does. Maxdlx
Are those rear brackets going to be strong egnough?
does the rear scissor action part your talking about look like its pushed back too far in the pic? should it be in the forward position?srx6 said:
im not sure on that distance, ill have to check with someone who has a mm and get that dimension.maxdlx said:
yes , they are 1/4" thick. i dont have it in a permenant location yet . the 2 bolts holding it are just for mock up.pro116 said:
keep the suggestions coming please.
The rear mount location does not appear right, as the geometry of the FRA in the pic is closer to the fully compressed condition than it is to the fully unloaded condition. Remember that there are 2 measurements for each hole. Center to center from a single point of reference, and distance from a single plane such as the top of the tunnel.
My guess is that the rear holes are too far from the front holes, and thus the center holes, or the distance of the rear or center holes from a single plane are wrong. Draw it out on paper and then refer to it as you measure if you haven't already done so.
If you want me to double check the numbers, I have them somewhere.

What was referred to as the rear scissor above is in the correct position.

i would appreciate any help i can get at this point. thanks
i was going to try moving the rear mount next, but wanted to ask someones opinion before trying something.
These measurements are for the 144 skid in a 2003 - 2004 Mtn Viper . . .
However . . .
Whatever point is chosen for the rear mount along this arc, requires a specific point on the center arc. One way to do this is to draw the center arc, and then measure from the rear to the point along the center arc where the noted measurement crosses this arc. This should occur at only one point for any rear mount height.
All that said, somebody on here had a real simple drawing that showed all of this, but it was quite a while ago.
- Front to Center should be 350 mm (between 13 3/4" and 13 13/16").
- Front to Rear should be 742 mm (about 29 1/4").
- The upper setting on the stock sled has the Center 127 mm (about 5") from the underside of the top of the tunnel, and the Rear 197 mm (about 7 3/4") from the underside of the top of the tunnel.
- This should make Center to Rear 400 mm (about 15 3/4"). They do not add up becasue they are on different planes.

Some of the guys on Snowest have done a great number of these and could easily verify my numbers.

it was just in the way it scissored when the suspension was pushed downthat the the bottom pivot point behind the transfer rod was going the wrong way going foward when it should have been going backwards or vice-versa.sory so long to post but had 5 hour drive today to get powervalve cables in time for possible ride this weekend!!!jas said:
appreciated. i was pretty close on the rear mount, just made a small adjustment, and got close enough. i removed the shocks and cycled the suspension up and down to make sure there was no bind. and after all that i pulled the tranfer rods and installed a transfer enhancement kit. and the skid travles great now. those measurements were much needed.Ding said:
i appreciate all the help.
