Laminating Rear Lower Control Arms

Post by Dyls GQ »

Next Week Im Thinking Of Laminating My Rear Lower Control Arms On My GQ. I've Just Got A Few Questions:

- How Thick Are The Stock Lower Arms?
- Should I Use Flat Steel? (I Hear People Also Use Angle)
- What Dimensions?
- Should I Stitch Weld Them, Or Completly Weld Them? (Slowly)

Im Thinking Of Using 8mm x 25mm by Roughly How Ever long They Are
And Will Probally Stitch Weld It But Any Feedback And Ideas Would Be Helpful

I've seen angle used and it was stitch welded. Thats all you need. Its only to stop them flexing and ultimately failing once bent. Be very careful though, the walls are not very thick and you can blow holes in them if you go too hot. I suggest picking up a set second hand and welding those. Then its just a change over job.

I sleeved mine with thicker walled mild steel pipe that has the inside diameter the same as the outside diameter of the originals.

Cut the originals in half and slid them in the new pipe, welded the ends and also drilled 4 evenly spaced 10mm holes in the new pipe and plug welded through to the originals.

Here is a detailed way of sleeving from patrol4x4 which includes panhard bars.

Think your more likely to bend it vertically rather than sideways?

I've just done mine but put the flat bar on the top - I think it will do more good on top because the the arms tend to bend upwards, if you hit a big rock and bend the bar over, it wont prevent the arms kinking up if that makes sense....

most using adjustable lowers have shortys and are trying to sort out pinion angles.

Best not to use them as lowers are subject to alot more forces than uppers and adjustable's threaded rod can be the weak link.

also, what you blokes are doing is "bracing" not "laminating" which essentially is adding layers to something. in other words "sleeving" the arms as seen elsewhere in thie thred, I think.
