I got my bar from towequipe.co.uk
Cost ~£100 for the bar/ball (£75), electrics and 7 way relay (£25). Took about 3 hours to fit (get a haynes manual, the instructions are vague in the extream). You’ll also need a torque wrench, some of the bolts are very low, the ones on the flange are beyond the reach of our 1m wrench (about 190N/m)! And had to cut off some superfluous brackets under the car that we couldn’t figure out.
I don’t know if they’ll all be like that, but we ordered the basic (own brand?) bar, and a witter one came in the box.Maybe a stock controll issue, or maybe they just bank on enough people paying for a branded one that it isnt worth stocking a seperate cheeper bar.
Wasn’t difficult but I had the tools and a garage and like fiddling with things. In general we found it easier to remove more stuff than less (so where it says peel back weel arch liner, we took off the wheel as well, and had back of the car 2ft in the air on axle stands etc. Did spend a lot of time trying to figure out why we were replacing one steel bar with another and why the manufacturers don’t weld the fittins on in the first place (the new stuff is thicker metal, but actualy less pieces/welding).
I’ll report back after I’ve done the electrics!
