The Redback Extreme Duty Auxiliary Fuel Tank Adaptor is a 3″ adaptor kit designed for 79 Series Toyota Landcruiser (Double Cab 2012‑on or Single Cab 11/2016‑on) when fitted with an auxiliary fuel tank ahead of the diff. This adaptor enables proper exhaust routing around the auxiliary tank — ensuring clearance while maintaining exhaust integrity and flow. Built in Australia from 409 stainless steel, the kit uses heavy‑duty 4‑bolt, 10 mm thick flange plates, extreme‑duty hanger brackets, and pressed fire‑ring gaskets for a secure, vibration‑resistant fit. It connects only to Redback’s Extreme Duty exhaust systems. Available in two sound/flow configurations: 5″ round straight-through resonator for a balanced exhaust note or muffler-delete (pipe-only) for maximum flow and aggressive tone. Finished with premium heat‑proof paint for long-term resistance to heat, corrosion, and harsh off-road conditions. Installation is relatively quick (approx. 1 hour), and the adaptor is backed by Redback’s 10-year warranty.
