I am nothing like ASPW and am not a Saffer. ARB is an Australian company and we use tons of their products and you also don’t need to integrate with crash safety stuff here either aftermarket (you do have to comply with Austrian Design Rules, but they are much lighter than OE vehicle type approval rules) but you do as supplied OE. Although it’s always a good thing if it is safer. If ARB makes a bar for the Grenadier no doubt many Australian Grenadiers will sport their bars with Warn winches. Red winches are not well known at the consumer level here either but are very well known and respected in the competition community. My point os merely that there are solid reasons why the OE winches are the configuration they are. Nobody saying you can’t or shouldn’t do something different aftermarket if you prefer.
ARB is from Australia??
Ronny Dahl makes it well known in his videos how much engineering, safety testing, airbag compliance ARB puts into their products. It's all valid. Too many bumper mfr's in the USA who have no regard for proper engineering (no American Design Rules here in the USA).
My perspective; IA engineers didn't spend more time to find a solution to allow a larger winch drum/longer line; maybe the bean counters capped their engineering hours. <shrug> There is the intercooler setup that could cause some issues yes. Their bumper/winch setup looks nice and compact against the IG, just disappointing that there's only 13m of winch line to work with.
Have a good day mate.
