Scag to scag distance for carbide runner set-up

Trying to get a measurement for the scag to scag distance on the new XM, as it comes stock. want to put carbide runners on the sled deck ramp tonight and want to make sure the neighbor's sled will fit!

Thanks!

Wondering what they are coming stock? And what is the ski width?

My neighbor gets his sled in 3 weeks... i am installing the carbide tracks on my sled deck ramp in the morning... the ramp is in the way, needs to be done and put out of the way

I am assuming that the skis are 8"wide... 4" outside of carbide, or offset???

My ramp is 48" have 6" Caliber carbide tracks

If I but them to the edges that leaves 36" in the center; if flush to one side on loading he hits the cross bars?

48 (ramp width)
- 4 (scag from outside edge)
= 44 (outside scag to other side of ramp)
- 35.7 or 37.4 (scag to scag)
~ 6.6 to 8.3" (center scag on inner ski) scags hit cross bars!!!

if i move them in 1"each that leaves 34" in the middle
~4.6 to 6.3" scags don’t hit... got to make sure no Simmons ski sleds load on ramp then.

Bottom line if the sleds come 37.4 stock then i can use 6" set in 1" on each side, otherwise i need to get an 8" guide.

If some one knows for sure or can go measure that would help make the decision.

Sorry for the long winded explanation, but maybe something you guys have to think about with these narrow new sleds?

Ah-ha XM's a little late, explains the 3 more weeks until buddy's sled is in.

I am thinking i have enough 8" for one side and offset the 6" in an inch... then he needs to aim for the narrow side just to be sure. Hope they come the 37.4" wide. if not; its not my sled:face-icon-small-ton
