Snowmobile Shock Service $95 Each Set Per End

The most important service we offer. Our rebuild is complete, thorough and the base point for all our service offerings. Before work has started everything is pressure washed, then completely disassembled and cleaned, inspected and measured for wear. All shock shafts are polished on our lathe with a three step process. Minor imperfections and burns are removed, and your shaft will move with reduced friction and seal life is prolonged.

As an incentive for maximizing your suspension investment, Moto-Tek always updates suspension that has been previously valved by us to latest specifications. As technology advances, you can continue to take advantage of our research. You will not find a more thorough rebuild anywhere.

We provide a wide range of parts and service for all snowmobile Shocks. KYB, ACT, Fox, Olin's, Walker Evans, HPG, Arctic Cat,(ACT), Are some of the types of shocks we work on.

- Complete Disassembly, cleaning and inspection of all parts
- 3 step chrome polishing on lathe
- Valving updates / changes at no charge for MXT revalved suspension

A perfectly fine looking shock may have the oil contents half water and oil. They’re sealed so how do they get like that? Shocks ingest water. Water acts like a cancer inside your big dollar shocks. Water dilutes the oil and damping action. Water freezes and lock ups shocks in cold temperatures.

From a performance standpoint there is the slow and gradual loss of the high pressure nitrogen charge that passes through the seals and into the oil. These are Internal Floating Piston (IFP) shocks that use a floating piston to separate the 200+ pounds of nitrogen gas from the oil inside the shock. This piston has o-ring seals around it, traveling up and down inside the shock. This movement of the o-rings inside the shock causes friction. Friction causes wear.

How long can you expect these seals to hold back hundreds of pounds of pressure? The seals slowly let the nitrogen pass. Once this happens, you now have an "emulsion" shock, where the gas and oil are mixed. The valve stacks that work with good oil and proper pressure are far different from what works with emulsion oil. Shock go "soft" after awhile, suspensions bottom out and then things begin to break.

The bumps in your paths get through the suspension leading to broken torque arms and suspension rails. Not to mention what it does to you. Shocks are in a constant state of deterioration. This Leads to the next frequently asked question. How often does one rebuild their shocks?

 

Suggested Service Intervals:


• Rider Type By Time By Mileage

• SnoX Racer Every other weekend

• Aggressive Rider Once yearly is a must and should be done in the spring 1000 miles

• Moderate Rider Once yearly is a must and should be done in the spring 3000 miles

• Sunday Driver Every other year but in the spring of the second year is a must 5000 miles

 

Set up Tips

- Most sleds are designed for 180# rider in general conditions. If you are heavier, go heavier on ALL the springs, and tighten up the rebound valving to control the higher stored potential energy of the heavier spring. Same for aggressive riders, or beat up trails.

- Your goal is to use as much suspension travel (without bottoming) as possible. That’s going to provide the most comfortable ride.

- The spring needs a minimum of 1" preload to retain the spring. Springs CAN kick the retainer out for too soft of a setting.

- Set your Sag for your riding style and trails. This procedure is outlined in the manuals.

- A dialed-in inexpensive shock (a shock that is tuned for your weight and riding style) is better than the trickest multi adjustable, triple rate, reservoir equipped shock that is not set up for your riding style. One mans soft is another mans firm so it is hard to generalize when describing shock action
