EvilFab - Cummins 2003-2007 S300/S400 Over Under Compound Kit
Complete side mount style S300/S400 compound kit! This kit is fabricated in house with high quality steel tubing and flanges, then test fit on one of our mock up trucks so fitment is always spot on. Kit works around factory shock tower, ac lines and coolant tank. Black Braided oil lines with high pressure AN style connections ensure a leak free oiling system. 100% v-band connections will ensure you don't blow any silicone couplers making this kit the most reliable on the market.
