Simmon's Artwork and Product Modifications




Double your bite


Their metal ski saddle was as long as the 3 bolt wear rods. This combination would only allow some flexing in front of the ski saddle like all the other plastic skis. The first flexing plastic ski was on the Crysler Snow Runner in 1979. It did not need a loop because the machine could be lifted with one arm.


Front loops were only added because snowmobilers needed something to grab onto so they could pullout sunken sleds.

Simmons or SLP???? / Silverbullet, Dec.29, 2003


I surely am a Simmons fan and have been for years (in fact Verlin Simmons had me demo and report back to him on a
pre-production pair in 1994). I ended up breaking one of them and he has since beefed them up on the critical areas.

  Unsurpassed Exageration  | My two cents worth

None of these claims are factual!


Simmons dual keel ski, is inferior to center keel skis on groomed trails. The inside keel wear rods are just over 2 1/2" closer, to the center of the track, making the sled tipsy. It's a well known fact, to those of us, who know it well!!!

There is no way their
1998 version will flex
the same as their 1994 ski.

Their hype is still the
same in their 1991 ad.

All these versions (and others) will function the same as long as the distance between the
wear rods are the same and attached to the vehicle (the same way),

Simmons ad says –


The Simmons skis excel in stability, flotation and incredible maneuverability. The skis flex to absorb bumps, resulting in added suspension to your sled, Whether you prefer the 6” wide Originals or the 10” wide Gen II’s these are the best performance ski on the market. Unsurpassed technology, snowmobiling has never been so fun!


Scotts Comments:

They do float better than stock skis, but then again, most stock skis are designed for use on groomed trails where most snowmobiling takes place.


Turning in powder is accomplished by the rider shifting his-or-her weight over the track. Longer tracks, taller lugs, more low end torque do more for flotation than skis.


“Stability” Skis with dual runners get squirrely because 4 carbides are trying to follow their own path of least resistance across ice and pavement.


“Incredible maneuverability” – The effort to turn the handlebars is greater than single keels because there are 2 keels on each ski. It gets easier the further the handlebars are turned because the outside keel raises off the surface. The catch is, because of this the downside carbide of the outside ski is 2 19/32” closer to the center of the sled than center keel skis. That means a center keel skis will turn better at speed!


“Skis flex” – Maybe in 1991. Today however, the top of the 4 keels are 26" long and the bottom of the keels are 17” long and 1 3/8" wide on top and 7/8" wide on the bottom. The full length of the ski is 42 1/2". Combined with forward motion the moguls would have to be really long to get any tip to tip spring.

The “Unsurpassed” technology claim is as bogus as the rest of their HYPE has been!
