Plastic ski conversion kits
« on: November 20, 2012, 06:34:41 AM »
These are complete kits to convert your 26" leaf spring sled (which I've test fit on Kawasaki springs) over to SLP SLT ski bottoms, loops, and carbides.  Full kit includes the leaf spring bracket, ski bottom, loop, and carbide set of your choice to adapt to your existing springs & shocks.

I had taken photos of them on Kawasaki springs, but can't seem to find them now so I'll have to re-take some.

I don't believe these would work for LTD or ceptors tho, due to them having a wider leaf spring...

They look awesome tho!

Thanks for the info.  They will only work with the 2" springs.

I posted a couple pictures in another thread under tip and tricks "plastic skis" of the plastic skins i've been using for years with the original kawi metal skis...

If I were to take the plunge on a pair of the plastic ones, due to the type of riding I do, which is usually in very deep snow. I would like a wider ski. The skins I use are 8 inches wide and I feel they provide an awesome amount of float, especially with a drifter, because they already float really really well!

Cheers! I really like them tho! What's the cost anyway?

I don't know the width of the ski off the top of my head, but I'm fairly sure they are at least 8", I'll check.  The kit is $469 w/ the 4" carbide.  6" is $10 more and 9.5" is $20 more (US $). 

This is SLP's description of the ski bottoms:

The SLT™ (Straight Line Tracking™) Ski is made of high quality UHMW plastic for a super strong, durable, wear resistant ski that is extremely slippery and remains flexible even in severe cold conditions. Its patented rocker keel design places more forward weight directly below the spindles for increased keel penetration and better bite in the turns. It results in precise, effortless steering in all snow conditions.

Unique Center Keel Design:
Center keel features an hour glass design with a concave front to minimize tracking even on frozen, rutted trails.

Outer Gull Wings:
Outer gull wings reduce darting, increase flotation by trapping and compacting snow underneath the ski, and increase turning ability by providing additional steering component surface area.

Carbide Combinations:
Multiple carbide combinations are available to match individual riding styles and snow conditions.
(PN 35-127 Carbide and PN 35-121 Keel Blade. This combination provides the maximum reduction of darting on groomed or hard-packed trails.)

Straight Line Tracking and SLT are Trademarks of Starting Line Products Inc.,
Ski design Patent #5700020, #6012728, and Patents Pending.

Plastic moves incredibly well on snow, especially compared to pitted metal!

I do wish you offered ones for the LTD's, cause it maybe something I would take the plunge on in the off season!

I doubt very many sleds use a 2 3/8 wide leaf tho!

Yea, that's too bad.  The brackets are almost exactly 2 3/8" wide on the inside, so the spring might actually fit snug, but the problem is the plastic wear pad on the front.  There would be no room for the sides of it, which is what holds it in place with the leaf retaining pin/bolt.

I was wondering if they would fit.

Could you or would you want to grind a little off the spring?

I would be tempted to put Invader springs and plastic skis on the LTD to ride and keep the LTD springs and skis for show.

I don't know how good an idea cutting down the springs is.  Invader springs would probably do the job.

These go for almost $ 450.00 new WOW. That would be nice to put on mine, But I can't see spending that much.

 It would depend how much you ride the sled.  I have them on a Liquifire that is my favorite trail sled. If it would snow and the trails open I would plan on putting 1000 miles on my Liquifire.

 New steel skis and carbides will set you back at least half that much. for the extra money the plastic is much nicer.

 I don't have that much invested in mine   but I do have about $350. invested.. I was lucky and found a pair of slightly used SLP skis locally and bought the adapters from Matt

Lloyd, my 4/6 came in with springs that were ground down to fit aftermarket ski bottoms.  They are a mess and I don't recommend taking this approach.  They didn't grind far enough back and when the spring compresses it gets jammed in the front receiver bracket.  If I remember I will try to get a photo.  I think that someone would be better off with Invader springs even if you had to add a spacer to get back to the right ride height.
