Product details
Alternative Impact 2102515 is a single 39" ski-stance chromoly lower a-arm for Polaris RMK and Pro RMK snowmobiles on the AXYS chassis, model years 2016-2018. It is sold as one arm; choose left (clutch side) or right (exhaust side) when ordering. It is the replacement lower arm for the Alternative Impact 2016-2018 straight-arm kits in this width, built with the heavy-duty lower tube (.009" thicker wall).
The arms use threaded rod ends at the spindle instead of welded or pressed ball joints. Alternative Impact designed this so that after an impact the rod end can usually be unscrewed, replaced with a spare and the ride continued, rather than replacing a bent arm. The manufacturer states this is not guaranteed but has worked in roughly three out of four cases. The upper arm is built with a wide radius so it clears any stock or aftermarket shock, including shocks with piggyback reservoirs.
Fitment. Polaris RMK and Pro RMK on the AXYS chassis, model years 2016-2018, 39" ski stance. Side-specific: left hand is the clutch side, right hand is the exhaust side. If you are replacing stock arms with these lowers, you will also need one steel 5/8" rod end and two misalignment bushings per arm (the Delrin bushings come pre-installed). The shock tabs are in a slightly different location on the arm, but the geometry is the same as stock. Custom powder-coat colors are available on request (RAL number from Tiger Coatings in the order notes) and can take up to three weeks. Model year is not a checkout option: enter your model year in the order notes at checkout.
