REAR SUSPENSION Suspension Troubleshooting
Problem Rear suspension bottoms too easily Solution Increase torsion spring preload Revalve your Foxt rear track shock for firmer compression damping(Can install "High Performance" shock kit but will affect ride plushness (PN 2873107)only on PPS) Increase torsion spring wire diameter Make sure Rear Rear Scissor Stop (RRSS) is in the stock position (see rear suspension set up decal) Increase compression damping by turning the adjustment knob on the rear track shock reservoir to higher numberIncrease FRA position (M10ACE)Increase Xover tube length (M10)Increase rear track shock compression damping (M10)Revalve rear track shock (M10)Check track tension (M10)-Check for binding suspension shafts and grease all pivot points -Decrease torsion spring preload adjustments -Revalve your Foxt rear track shock for softer compression damping Decrease compression damping by turning the adjustment knob on the rear track shock reservoir to lower number Decrease torsion spring wire diameterDecrease FRA (M10ACE)Decrease rear track shock coil spring preload (M10)Change to optional soft rear track shock compression spring (M10)Check Track Tension-Make sure skis are aligned properly-Make sure spindles and all steering components are free turning-Make sure skags are straight on skis -Reduce ski pressure: DIncrease front track spring preload DReduce IFS spring preload by adjusting threaded collarDReduce rear torsion spring preload Ensure use of AccuTrakt dual skags (M10)-Check for worn skags-Check for binding suspension shafts and grease all pivot points-Increase IFS spring preload by adjusting threaded collar-Adjust RRSS to higher position Shorten front limiter strap (M10)
