Finally a complete package for the 2017-2019 X3! This kit come complete with new factory 2020 BRP cover, insulating mat and hardware(uses your factory attaching bolts), new Dirtbag Customs Carbon Fiber slip in liner and a new Razorback belt temp gauge! The 2020 cover has a completely redesigned airflow system which during our testing can drop the belt temps as much as 20 degrees! This combined with a temp gauge to see what’s going on on those hard dune drags or rock crawling and the only indestructible clutch housing liner in the market (over 1000 out there with no reported failures!) your belt and housing worries are over!
