A BDS Exhaust Extension Kit is required for proper driveshaft clearance after installing a lift kit on your 2012-2018 Jeep Wrangler JK. When installed this kit adds clearance between the front driveshaft and the passengers side exhaust crossover tube. Precision CNC-machined DOM steel tube spacers fit tightly to the factory exhaust flare joints which ensures no exhaust leaks while still maintaining adjustability. New hardware is included. The bolt-on design is completely reversible. This kit is a required accessory for BDS JK lift kits and is probably a critical add-on for other brands of suspension systems on the market where exhaust-to-driveshaft clearance is an issue.Additional Attributes:GTIN:00711745605015Installation Time:1-2 HrsMaterial:SteelMounting Hardware Included:YesProp 65 (C| R or CR):CRProp 65 Short Label:WARNING: Cancer and Reproductive Harm https://www.p65warnings.ca.govProp 65 Warning Label:p65.jpgProp 65 Yes/No:YesPvg Product Status:ActiveExtended Information:Emissions :Emissions Compliance ExemptLife Cycle Status:Available To OrderPackaging:Quantity of Each:1Package UOM:EADimension:9.0000 x 3.0000 x 2.0000 inchesWeight:1.3000 PG
