Outer Limits 4x4 Board

Just wondering what peoples opinions are on rock slider mounts for a sierra. do most people mount them off the chassis or bolt a right angle plate etc. to the body?

bit of a search.

Everyone I know that has bolted them to the body has chrashed the sill.

Best option is to bolt them to the body mounts that come out from the chassis. There is one at each end. I used to have some right angle which fit nicely along the body. I came down on them a number of times without any probs.

Hope that helps

Dewse, got any pics of you had it?

I am guessing you had it between the spring perches? or onto the body mounts. Did you extend bolts or into chassis?


cheers

Yeah on the crossmember that holds the body mounts and the spring perches.

No pic's sorry.

If you're not fussed on engineers etc, weld crush tubes through the chassis and bolt your sliders to that. On a SWB sierra i would suggest 4 mounts per side with 3-4 bolts per mount.

If its over engineered you won't rip them off.

Remember that you need to make the bottom side as smooth as possible, you need to slide with sliders. Too many people build them so that they will hang you up on obsticles.

mean't take some pics the last time this came up...
These are the slider/bash plates I made for my zook freshly back from the galvaniser.
Basically 3 pieces two "wings that bolt on to the outriggers that hold up the body and a plate that bolts up to that.
I raised the t-case a little before doing this and sacrificed a little clearance under the chassis rails. Put a small dimple in the plate for the handbrake drum that still hung below.
Things I'd do different:
1) put a small snout on the front of the slider rails, they've never been a problem cos there pretty protected by the spring hangers, but I'd do it on priniciple.
2) build it for Galvanising from the start- I had to drill and later plug a bunch of holes to do this.
3) put one extra bracket for mating to the outriggers I'll probably retro-fit this at some stage anyway.

This has been a great mod even though I sacrificed a little ground clearance in some parts. I've landed full weight on it several times and just slid straight over stuff.

Additional side benefit has been the extra weight down low, whilst I was driving it around recently when the bits were being galvanised, I really noticed that it wanted to tip over earlier on those pesky side slopes.

Does your rear driveshaft hit on full droop?

Heres how I did my zook ones.
Mounts to the body mount at each end and around the chasi in the centre.
Loose a bit of clearance under the sill but the chasi is still lower anyway.

nope front and rear just clear. Front did just scrape once but a minor mod with giant shifter fixed this. :-)

jsut drill 3 new holes in the chassis, one in the middle and to near the spring perches, i had this on my last hilux with side steps.

Hey Mike, just wondering how that BL is holding up?

and as for the sliders, i will be mounting mine to the chassis rails. although Vitara and Sierra chassis rails are different, its sorta same anyway.

Ok BL = Body Lift doh!
Mine was a GRP kit and frankly it was a waste of time. It was just some 50mm box section that had to be welded to the chassis and a buch of spacers and bolts...
If I was doing it again I'd use some solid bar and tap it. or maybe even some hollow steel bar if the right internal dia can be found to tap...

what thinkness material did u use?

how has it been holding up?

3mm on the bottom plate 2mm on the sides that is framed out with 25x1.8mm box mounting plates are 5mm.

It's been great, have been able to attack stuff more aggressively. and had no real problems. With the way I currently have it the bolts need to be super tight, it would really benefit from the addition of one more bracket. It's been on for around 12 months now

dosent seem like it would hold up

have u actually been high centered on a rock or anything?

not so much high centred but a couple times I've smacked down on a rock with full weight on the plate and it's left some gouges but that's about it. I was prepared to reinforce the plate but haven't needed to yet, if needed I'll put a lattice structure above it. I would've preferred to make the lower plate out of bisalloy but can't get it that thin here.
