The 1.5" lift kit is great if you are looking to clear larger tires on your 4x4. This lift can be used safely with OEM axles, thus being a very affordable way to gain the necessary clearance for those large mud tires. Axle Spacers are included with the 1.5" lift kit to prevent the front axles from popping out of the differential. NOTE: If using stock rims you will need wheel spacers on the rear. Fits: 2005-2017 Arctic Cat 400-1000H2 (TRV's included) does not fit 2015+ Alterra, XT and XR models. Call if you have any questions.
