Popular Custom Builds and Retrofits For Snowmobiles

One area of the market we have spent a lot of time developing is retrofits and custom builds on sleds. We have focused on the budget and in season models the manufactures have sold for years. The biggest cost savings to the manufactures to allow these units to be priced lower than higher end models are the shocks. We have solutions that can give you the edge over even the top models, the Polaris Indy, Shift and Rush models. Skidoo TNT, Sport and Adrenaline and Arctic cat LXR. All of our shocks are reconditioned, new seals and wear components and carry a 1 yr unlimited mileage warranty.

*Since these builds require used core units its best to inquire as to current inventory. We normally have enough inventory to meet customer demands.


Front Shocks:

  1. Walker Evans

From 17” to 18” the front of the xp/xs has a lot of options. Our most popular build for these is the Walker Evans Piggyback clicker Needle shocks. We suggest 17.5” Length to help with high speed cornering and roll in the corners. We prefer the units with spherical bearing eyelets for wear and longevity as well as help with eye to eye offset during suspension travel. We open the spherical bushing up to 10mm slug the shock to 17.5 (or your desired length) valve and spring* them according to the machine and rider weight and you’ve got a front clicker piggyback shock setup for 625$

*Standard package comes with a single rate spring, dual rate spring kits available as well for addtional 225$

Clicker center shock.


Monotube Center shock.


Arctic Cat


Most cat sleds have rebuilable shock setups right out of the box. With Either ACT, Fox or Ryde FX setups we can repair most any shock for the cats, we have some retrofits available but with new fox selection it’s tough to justify the price of used when new is so close ,  Some of the Sabercats and older ZL sleds came with Ryde FX through away shocks so we carry a lot of fox units for these applications as well as the new procross cat and yamacats we stock front fox qs3 and qs3r units and build fox zero pro piggyback clickers for these sleds (Inquire about availability, current pricing and other shocks not covered here)
