Your factory hoses are already failing. You just can't see it yet.

Yes. Every kit is a direct factory replacement for the chassis and years listed under it — same routing, same bends, same clamp positions. Nothing here is universal hose cut to length. If your car has been modified around the plumbing, send us a photo first and we'll check it.

Mostly things you can’t see in a listing photo.

Silicone hose is cured twice. The second cure — hours in an oven at around 200°C — drives off the volatile by-products the first one leaves behind. It’s slow and it costs energy, so it’s the first corner cut on a budget line. A hose that skipped it looks identical when new, then bubbles, delaminates, goes tacky on the surface and loses tensile strength once it has seen a few hundred heat cycles.

Ply count gets quoted a lot and means less than people think. The reinforcement fabric between the layers is what actually holds pressure — a thick hose built on cheap polyester is worse than a thinner one built properly. Burst figures are the same story: they’re quoted cold and fall away as the hose heats up, so a big number on a listing can still describe a hose that’s marginal at operating temperature.

Ours are four-ply, rated to 100+ PSI and to fifteen years of service across −60°C to 145°C, and moulded to your chassis rather than cut from universal bends. Worth asking of anything you’re comparing them against — and if the listing won’t tell you, that’s usually the answer.

We recommend new ones, for three reasons. Your existing clamps may not close down far enough on silicone — the wall thickness isn’t the same as rubber. If they’re twenty years old they may be seized, rounded off, or simply awkward to get a driver onto in situ, and you don’t want to discover that with the coolant already drained. And if you’re running more boost than factory, you want a clamp rated to hold at that pressure rather than hoping the original will. Worth doing while everything’s already apart.

Yes, within 30 days, subject to our returns policy. Return postage is at your expense. If something’s gone wrong outside that — wrong part sent, or you’ve ordered in good faith and it isn’t right — email us at info@rooracing.au. We’d rather have a conversation and find an outcome than leave you stuck with a part you can’t use.

Free on orders over $500. Under that, you'll see the exact shipping cost at checkout before you pay. Everything ships from Campbelltown NSW, and we check fitment against your car before it leaves us.
