KKtrips Posted November 5, 2012 Share Posted November 5, 2012 You can buy them from the states already done for cheap. Heaps of companies make them. Try Superbell for their 5" drop version. o_O Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted November 5, 2012 Share Posted November 5, 2012 Be wary of the Magnum ones though! http://lvvta.proboards.com/index.cgi?board=general&action=display&thread=274 Quote Link to comment Share on other sites More sharing options...
cletus Posted November 7, 2012 Share Posted November 7, 2012 whats the deal with dropped beam axles on old as stuff/hotrods? is this legit? like oldshool heat the thing up put it in a huge press with a jig and heat treat it afterwards or something? e.g. this type of thing asked about this today, there are a couple of nzhra approved engineers who can do it, and they are the only ones who can for cert purposes. Dave Mcdougall is the one i can remember. one issue is the type of axle it is, the only jigs available will be for early ford, not other types Quote Link to comment Share on other sites More sharing options...
danger Posted November 7, 2012 Share Posted November 7, 2012 Do I need to be special to weld to my chassis? Ie box section and shorten the rear legs and lower the front leaf mounts/ make shock mounting hoops on my hilux? Quote Link to comment Share on other sites More sharing options...
Testament Posted November 7, 2012 Share Posted November 7, 2012 asked about this today, there are a couple of nzhra approved engineers who can do it, and they are the only ones who can for cert purposes. Dave Mcdougall is the one i can remember. one issue is the type of axle it is, the only jigs available will be for early ford, not other types so its not often done but may be possible and would require significant consultation for signoff?

Nominal Posted November 8, 2012 Share Posted November 8, 2012 so its not often done but may be possible and would require significant consultation for signoff? It's is fairly commonly done for early ford forged axles. The pics you posted are for leaf springs or something, so might be a bit harder to get done.

The pics you posted are for leaf springs or something, so might be a bit harder to get done. yeah leaf springs, chevy 41-54? or thereabouts axle - initial investigations indicate they used the same front axles in most things of that period? the pics are from http://www.droppedaxles.com/ in the states. it looks like a bend and slight stretch and maybe puts a little extra negative camber (for racing lols) Quote Link to comment Share on other sites More sharing options...
cletus Posted November 8, 2012 Share Posted November 8, 2012 its not as common as it used to be, a proper dropped axle isnt as expensive these days. i doubt many people would do a full fendered car (40-on) with a dropped stock axle that isnt a ford, most end up with some sort of independent front end Quote Link to comment Share on other sites More sharing options...
craig_b Posted November 8, 2012 Share Posted November 8, 2012 yo cletus, my cert plate says the engine config in my car is a inline 4, as far as im aware it has never had a 4cyl in it, could this likely be a f*ck up on the person that prints the plate? also can it be corrected without going for another cert? was done before the car came into my possession. also could vinz/vtnz be able to look up who certified it if i give them the cert number or rego etc?

spiderwebfx Posted November 8, 2012 Share Posted November 8, 2012 For a cert do rose joints have to be kevlar lined or will they settle for teflon lined ones? Got a set of Techno Toy Tuning 4-links for my s12 and they are Teflon lined, I'm now hoping I can actually certify them. Quote Link to comment Share on other sites More sharing options...
cletus Posted November 8, 2012 Share Posted November 8, 2012 Do I need to be special to weld to my chassis? Ie box section and shorten the rear legs and lower the front leaf mounts/ make shock mounting hoops on my hilux? no qualifications needed, you may need to show your certifier you can weld though. youd be fine Quote Link to comment Share on other sites More sharing options...

spiderwebfx Posted November 9, 2012 Share Posted November 9, 2012 kevlar or teflon is fine. Awesome stuff, thanks for the reply! Also, while I'm at it, what is the main reason for rose joints / cheap aftermarket arms failing certs, and are their any special requirements for aftermarket tie rods ends as opposed to any other rose jointed end?

flyingbrick Posted November 13, 2012 Share Posted November 13, 2012 hi all. so I had this photoshop done ( thanks Dylan) and I reckon it looks fuggin great. iv had a look at the lvvta website and its a but confusing. it says " no " then it says I could have a metal stone guard.... if I made a grille out if stainless rod and kept coverage to less than 50% total do you think there is any way it could be legal? other option is making the bits that cover the lights removable for wof time and driving at night Quote Link to comment Share on other sites More sharing options...
