Hey guys we have 2017 MY17 Isuzu mu-x with original bar. 550mm centres using sliding mounts. just a little concerned about the set back when using the sliding brackets. (clearance from hole centre to grill)
What is the maximum distance apart for the adjustable mounts, and is the absolute overall length 28*?
I have a Holden Colorado with genuine bull bar and the holes are pre-drilled at 540mm centres, and the gap between posts is 710mm. This looks like it might be a tight fit?
I have a 2017 Navara d23. Which wiring harness would i need for the Stk-4 28inch double row?. Also do you sell your lights without included harnesses as I need to buy the specific np300 one i believe.

First Rate Product, well packaged, good quality hardware.

very impressed with the light output, great spread with a spotlight like throw. the only light i need. the only negative is dipping back to low beam after driving with the light bar on!!

Highly recommended (Posted on 11/11/2017)

Nope . These Are great .easy wiring set up ,strong brackets and the light will kill any vampire that flys into your path .im even concidering removing my other spot lights and just use the bar , im really impressed thanks stedi (Posted on 30/06/2017)
Brilliant Light
Review by Gimpster
I was so impressed by the 14" 4k light I purchased for the wife's little SUV, I went and purchased the 28* for my 4x4.build quality is IMPRESSIVE, delivery is fast and free. Wow wow wow brilliant light, fantastic spread and throw is like a pair of high quality spot lights. My only slight grumble is in design, the entry point for the bottom mount sliding brackets is around a third of the way across the bar, not at one end. It was right where I wanted to mount the bracket, had to offset one bracket. Not a huge deal but the only thing NOT PERFECT for me. (Posted on 24/06/2017)
The beast!
Review by Andy F
Wow, what a piece of kit! I have attached this light bar to my peugeot 307 wagon. Amazing light distribution and spread with plenty of throw. For me, it is the perfect size; i dont feel like its lacking any light, and im definitely not left feeling there's too much light! it just hits the spot! Great build quality, extremely easy to install wiring harness, all to a high quality.
Will most definitely be buying some more lights shortly! (Posted on 25/05/2017)
Brilliant. Fantastic bit of kit.
Review by Cooper M
Excellent build quality in the bar itself and in the fittings, from the mounts to the bolts supplied with the bar to the included wiring harness.

The light bar was very easy to install and took me about an hour and a half to get it fitted and working. Everything you need is supplied and I was surprised to see more than enough length in the harness to route the wiring exactly where I needed it to go.

This bar produces an incredible amount of light and in a colour that is really easy on the eyes. It's not too blue like the cheapie light bars can be. The spread of light is even and really gives you that peripheral vision to the sides of the road that is so important when driving on country roads.

The staff at Stedi were an absolute pleasure to deal with and I would not hesitate to buy more of their products as and when the need arises.

I highly recommend this light bar to anyone looking for a ridiculous amount of light without the need to go for a set of expensive spot lights. (Posted on 30/03/2017)
Darkness begone!
Review by Eugene B
I live in the country and I regularly drive to work on dark roads lined with suicidal kangaroos. This bar has such amazing spread and throw that it almost makes spots redundant. This thing is built like a tank and was straightforward to install thanks to the quality harness.

Stedi were brilliant to deal with. I thoroughly recommend them and the ST4K light bar. Don't bother with cheaper brands, this is the sweet spot between quality and price.

Enjoy the dark!
