Xtreme XP Rear Summit

 |
The Xtreme XP rear suspension upgrade kit effectively upgrades your 2008 and 2009 Ski-Doo Summit "X" or Summit Everest to perform like the 2010 sleds. In 2010 Ski-doo finally got the rear suspension set up correctly. The rear suspension on a 2010 summit performs much better than the '08 and '09 summits. The rear Center shock was lengthened and moved back 1" on the rail. This change makes the XP summit roll over and side hill MUCH easier. You will notice substantially less ski pressure and the ability to pull the sled over much easier. This upgrade helps transfer spring pressure from the front shock to the back shock to help the sled jump up on top of the snow much quicker. This also helps remove the "sag" in the rear end that many doo owners have complained about since the '08 came out. With the center (track) shock being longer, the front arm is forced up, which forces the back of the sled up through the pivot and transfer rods. Contrary to popular belief the longer front shock does not make the XP wheelie uncontrollably; in fact it does the opposite. Because the front track shock is now carrying some of the load under power, the rear does not collapse as easily.
We have
partnered with Deycore
Enterprises to build our custom shock. The shock is
rebuildable
with all FOX components. This shock has an all stainless
steel
shaft, billet machined eye brackets, billet spring adjusters, billet
spring retainer and gold
anodized aluminum body. The shock has custom progressive
valving
to better resist bottoming. The new custom shock has more
adjustable range than the Doo shock for a truly customizable
ride.
The
kit comes complete for easy do-it-yourself installation. It
comes
with a
new custom rebuildable center shock, new shock relocation brackets,
hardware,
new longer Ski-doo limiter strap and color instructions. The
rear
skid does NOT need to be removed
for
installation. The stock spring is re-used on the new shock to
keep the
factory ride. The front idlers can be re-installed (the above
picture has them removed to better view the kit).

We also highly recommend the 2010 steering post upgrade for the ultimate in lighter steering. You can see how to do this for free here.
Xtreme XP Complete Summit Rear Suspension Upgrage Kit.
(146,154,163)
This kit includes all the same features as above but also includes a new custom rear shock. Now you have the opportunity to completely upgrade your rear suspension with custom rebuild able shocks for an affordable price. In '08 many of the rear shocks that came from the factory were low on nitrogen. This causes the shock to bottom very easily, fade and wear out very fast. Many Ski-doo owners complained about the sagging rear suspension that bottoms too easily. This kit fixes these problems. The new custom rear shock is rebuild able with all FOX components. It has custom progressive valving to better resist bottoming.
