Configure your iSi system.

Five: tow bar receiver height to ground, tow bar overhang from rear of vehicle, factory or modified departure angle, rear accessory clearance (drawers, fridge slides, doors, swing-aways) and vertical clearance below the tow bar. Each one is mapped to a specific component in the configurator — see the Measurements Guide above.

Yes — that's exactly what this is for. Trayback utes, custom canopies, rear-mounted spare wheels, drawer systems, fridge slides — pick your departure angle, beam length and pivot base profile to suit. If your configuration is unusual enough that the configurator doesn't offer the right combo, the configurator will flag it and we'll talk options.

30-day fitment promise. If your custom-spec rack doesn't fit as configured, swap the affected component at cost — never the whole rack. Because the system is fully modular, that usually means a different pivot base or main beam, and you keep the rest.

Standard manufacture lead time is 5–10 business days from order confirmation, then dispatched from Mitcham, Victoria. Need it faster? Get in touch right after ordering — we'll see what we can do.

Yes — the modular architecture is the entire point. Swap the pivot base when you upgrade vehicles. Swap the main beam when your departure clearance needs change. Add a caravan drawbar mount and use the same rack on a caravan. Replace one part, keep the rest.

Yes — every iSi rack mounts to a 50mm square hitch receiver. iSi doesn't supply tow bars. Hayman Reese, TJM, Milford and most major brands are compatible. Confirm your tow bar's rated capacity supports the combined weight of the rack plus loaded bikes.

With an additional drawbar mount system, yes — under one minute, no tools. The same custom-manufactured system swaps between your tow vehicle and your caravan. See caravan bike racks →
