Thread: Rock Sliders - Sill or Chassis mount?

I'm half tempted to make boat sides and a skid plate but it might be getting a tad carried away...

If you're going to get carried away... make some sill tanks to hang off the chassis outriggers, make them with robust bottoms, add about 25 litres of fuel per side. They don't need to be as big as regular 45 litre sill tanks to be still useful. Could be water tanks too.

If you are making true sliders, try finding images of the ones Haultech made. They were very well made and mounted to the sill.

East Coast Rovers in the US used to weld plates onto the sills and then mount sliders onto them. They had some photos on their site ages ago. I used to have sidesteps on my Rangie when I got it, but they were mounted onto the chassis on very long arms. I hate to think of what sort of leverage I was putting on the chassis rail whenever I stepped on one. They've been removed for good. Some sidestep/slider things will definitely go on the sills when I get around to it.

My 110 sliders are mounted to the sills, mates gu patrol sliders are mounted to the chassis and the pipes from the sliders to the chassis tend to snag and bend= removing and straightening after a good day out

On an RRC chassis you would have to weld tubes in or it would crush at the first hit.
Ex boss with FJ Cruiser was boasting about his chassis mounted sliders and I noticed some bolts missing."Oh the captive nuts inside are broken"

I think that sill mounted is better if supporting the bottom of the sill. Most use rivnuts but this is OK if there is an angle iron piece underneath the sill.

I once was guiding a bloke up some rock steps at Yalwal and he flattened it and spat out the built up rocks, and she came down with a crash. Bent the body in the middle and the doors wouldn't open.

Thanks, Maybe I'll make some normal sliders first... that can be stage 2, along with the bobtail and roof removal

Thanks Serg, you wouldn't happen to have any photos would you? I can't find anything with google (except new ideas of mods that Sam has made!), btw what ever happened to Haultech? Looks like they are an AC company now..?

Thanks Philip, Do you mean to put crush tubes in the chassis if they were chassis mounted? Or are you saying to mount them on the sills, but use crush tubes and plating to strengthen the area?

Mine had some angle-iron bracketry that went around the outside, top, and bottom of the chassis. On the inward face of the chassis was a big bolt, clamping the whole lot. Don't do that! The chassis is actually a bit squished from this. It's funny, the steps look professionally made, but the design is crap.

Here, I found the ECR page: Range Rover LWB Upgrades

If you're making them yourself, you can't go past the DWE design.

Unfortunately, some of the pictures are long gone but I'm sure you can work it out.
