Understanding the 2006 Apex Suspension System
The 2006 Apex uses a four-stroke engine with a lightweight chassis, and its suspension is designed for aggressive trail riding. The front suspension is a double wishbone design with aluminum A-arms, while the rear uses Yamaha's ProActive rear suspension (PRS). Key components include:
- Front shocks: Typically gas-charged KYB shocks (some models have GYT-R clicker shocks)
- Rear shocks: One main rear shock (KYB or GYT-R) and a smaller shock under the tunnel
- Sway bar: A 18mm sway bar for reduced body roll
- Springs: Coil springs front and rear, with varying rates
- Bushings and pivot points: Many plastic bushings that wear over time
- Limiter straps: Adjustable straps controlling ski lift
- Control rods and links: Connecting the rear skid to the frame
When to Replace 2006 Apex Suspension Parts
Age and miles take a toll. Look for these signs:
- Excessive sag or bottoming out: Worn springs or tired shocks
- Clunking noises: Loose bushings or worn ball joints
- Harsh ride: Shock oil breakdown or nitrogen loss
- Uneven ski wear: Misalignment or bent components
- Sagging rear end: Worn torsion springs or broken control rods
If you own a 2006 Apex with over 5,000 miles, a full suspension rebuild is likely needed. For lower-mileage units, focus on shocks and bushings.
Front Suspension Parts for the 2006 Apex
Front Shocks
Two options: replace with OEM replacements or upgrade to aftermarket. KYB shocks are reliable but can be re-valved. GYT-R clicker shocks offer adjustable damping. Aftermarket brands like Fox, Elka, or Hygear provide better performance and rebuildability. Expect to pay $200-$500 per shock.
Front A-Arms and Ball Joints
The aluminum A-arms are tough but the ball joints wear. Moog or Yamaha OEM ball joints fit. Also check the A-arm bushings. Upgrade to urethane bushings for longer life. If the A-arms are bent, replace them as a set. Spindle assemblies are also available.
Sway Bar and End Links
The stock sway bar rarely fails, but end links wear out. Replace with greasable aftermarket end links for improved handling. Sway bar bushings are also common wear items.
Rear Suspension Parts for the 2006 Apex
Rear Shock Options
The main rear shock sees heavy use. Rebuild kits from KYB or GYT-R cost around $100 and restore performance. For a true upgrade, consider a remote reservoir shock from Elka or Fox that allows independent adjustment. The smaller under-tunnel shock (called the "bump shock") is often forgotten but critical for ride quality.
Torsion Springs and Control Rods
Torsion springs sag over time. Measure free length and compare to specs. Replace with OEM or aftermarket (often stiffer). Control rods can bend if the sled is jumped. Check for straightness; replace if needed.
Limiter Straps and Pivots
Limiter straps stretch and fray. Replace them with OEM for correct geometry. Pivot bushings in the rear skid wear out, causing side-to-side slop. An upgrade to oilite bushings reduces friction.
Slide Rails and Hyfax
The slide rail hyfax (plastic wear strips) need replacement every 1,500 miles. Use Yamaha's X-Factor hyfax for durability. Check rail condition too.
Where to Buy 2006 Apex Suspension Parts
Original Yamaha parts are available at authorized dealers. For aftermarket, specialty snowmobile shops like Snowmobile Suspenion Specialties, Hygear, or Shock Therapy offer parts and rebuilding services. Many online retailers stock common items. Always verify fitment for the 2006 Apex (model codes: APEX, APEX GT, APEX ER, etc.) as some parts differ.
Installation Considerations
Replacing shocks and springs requires basic mechanical skills. For the rear suspension, you'll need a jack and the ability to compress springs safely. Bushings often require a press. If you're not confident, have a shop do the work. Common mistakes:
- Over-tightening bolts (use torque specs)
- Forgetting to preload springs before mounting
- Misaligning rear suspension during reassembly
For performance upgrades, consider valve tuning to match your weight and riding style. Many companies offer custom setups.
Cost Breakdown
A basic rebuild (shocks, bushings, hyfax) might cost $300-$600 in parts. A full upgrade to premium shocks and urethane bushings can reach $1,500. Higher budgets allow for complete front and rear suspension systems.
Final Recommendation
For most 2006 Apex owners, the best approach is a balance of restoration and performance. Start by replacing all worn bushings and hyfax. Rebuild or replace the shocks with a quality aftermarket option that is rebuildable. For the rear, consider a replacement torsion spring pair and a heavy-duty control rod. These changes will transform your ride without breaking the bank. If you ride aggressively, invest in clicker shocks for adjustability. Always stick with reputable brands and check fitment carefully. With proper care, your 2006 Apex suspension can deliver many more seasons of smooth, confident riding.
