Our 9" Big Wheel Billet Axle kits eliminate more rolling resistance and a wicked look on your Summit or Freeride. The billet TKI axle is the best in the biz and the Avid Wheels are top notch. We offer this in a 2 or 4 wheel version. The flatlanders like the 4 wheel kit and can pop the two outer wheels off and throw them in the trunk for powder riding and the center wheels stay tight. This a complete bolt-on and installs in 30 minutes. The 2 wheel kit has a billet 2 wheel billet axle and 2 avid 9" wheels. The 4 wheel kit has a 4 wheel billet axle and 4 Avid Wheels with the ability to convert to 2 wheel in two minutes. The 4 wheel kit is pictured on a 2015 Summit with T-Motion. This kit fits 2008-2018 Summit including 2018 REV GEN4 Summit and Freeride models with factory 200MM wheels. Axles come in silver or black-specify in "notes" when ordering.
