Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Snowmobile Shocks
- Compatibility: Verify shocks fit your snowmobile's make (e.g., Polaris, Ski-Doo, Arctic Cat, Yamaha) and model year (e.g., Polaris 600 INDY, Ski-Doo MX-Z 600, Arctic Cat F1000 EFI). Use the vehicle selector for precise front/rear positions, eyelet sizes (e.g., 0.625" ID), and lengths (7.375"-15.625") to ensure seamless replacement without modifications.
- Type of Use: For trail riding or hardpack, choose hydraulic shocks for consistent damping; rugged terrain or mountain climbing benefits from gas-charged options for fade-free performance and better control in extreme cold or deep snow.
- Components and Upgrades: Select hydraulic/gas-charged shocks, replacement shafts (e.g., 1/2" diameter, 6.45"-13.19" lengths), eyelets/bushings, or spring protectors. Focus on features like hard-coat chrome-steel for corrosion resistance, billet construction for strength, and OEM-spec fitment for durability and reduced vibrations.
- Brand and Quality: Opt for Parts Unlimited for exact OEM replacements, HyGear Suspension for durable shafts/eyelets/bushings with hard-coat finishes, or Kimpex for gas-charged shocks. Prioritize materials like chrome-steel and billet steel for superior strength, longevity, and performance in harsh winter conditions.
- Installation and Cost: Most are direct bolt-on replacements with included hardware for easy DIY setup. Prices range from $8 for bushings to $54.95 for premium shafts, with full shocks at $31-$37—watch for sales and free shipping over $99 for value.
Frequently Asked Questions (FAQs)
- What snowmobile models do these shocks support? Shocks are compatible with brands like Polaris (e.g., various models), Ski-Doo (e.g., MX-Z 600), Arctic Cat (e.g., F1000 EFI), and Yamaha (e.g., general models). Use the year/make/model filter for exact front/rear fits.
- Hydraulic vs. gas-charged shocks: Which is better? Hydraulic (e.g., Parts Unlimited) provide precise control for trails; gas-charged (e.g., Kimpex) offer fade-free damping for rugged terrain, improving stability and flotation in deep snow.
- Do these shocks include installation hardware? Yes, most come with necessary hardware; replacement shafts and eyelets (e.g., HyGear) are designed for easy, direct OEM swaps without additional tools.
- What materials ensure durability? Hard-coat chrome-steel (e.g., HyGear shafts) and billet steel eyelets provide corrosion resistance and strength, outperforming OEM in extreme cold and abuse.
- What if a shock doesn't fit my sled? Verify eyelet sizes, lengths, and model compatibility before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related suspension parts? Yes—explore slides, wheels, or full kits in the snowmobile suspension category to complement your shocks for optimal handling and ride quality.
