Hot Rod Sled Shop 4 Spring "Drop-In" Kit--This complete Rear suspension Spring Kit for "X, Sport, & Adrenaline" models (ALL MODELS WITH UNDER 2" SHOCK DIAMETER) includes our HD rear torsion springs and our H5 dual rate center spring setup with a Delrin spring separator. The H5 dual rate center spring setup is only for ski-doo shocks with a diameter under 2". The oem R-motion rear torsion springs are shot in 1000 miles or less. We get calls every day with guys bottoming and cranking the adjuster all stiff to no avail.....this is the cure with superior rear springs and a dual rate center spring combo that rides smooth but doesn't bottom AND works well without valving work. These are not Ski-doo's "heavy" springs listed in the catalog which generally ride too stiff for most guys. It was tested and designed for a more agressive ditch banging style of riding where the stock setup is bottoming excessively. It still retains the smooth R-motion ride and still works very well with the stock shock valving or we offer our own valving package for individual needs. It also works really well for heavy riders (up to 300lbs.).
Spring kits are offered for all 2012-2021 models with the R-motion suspension and a center shock diameter under 2" in the dropdown menu. This does not fit XRS models or 2021 R-motion X rear suspension sleds. This package still rides extremely smooth and several test riders of varying weights thought it was the perfect combination for the R-motion suspension.
Please call about our revalve package for more agressive riders that includes this spring kit.
