Lowering my 320

[320inSpain]

Hello everyone, I just bought a 320 and will be shipping it from UK to Spain where I now live.

WHat is the safest way of lowering the truck allround? Would need to meet annual safety test.

Thanks for your help.

Lowering blocks and reindexing of the torsion bar.

 

 

There are other ways...that's just the cheapest/easiest without having to fab the entire front/rear end.

It would depend on what they are looking for in the inspections, if they want it stock looking then you are pretty limited, adjusting the torsion bars and 720 4X4 leafs in the rear are the only things that will appear stock, if lowering blocks in the rear are legal then that would be the easiest way in the rear.

You could have flatter rear leafs made over here in the US, don't know if that is an option in Spain.

I have heard of safety inspections rejecting the use of blocks (for lowering or lifting).

There are spring services that 'Re-Arch' leaf springs. A competent craftsman should be able to increase or decrease the amount of arc in a spring set. Should leave them appearing original stock. Look it up on net.

Thanks for your replies!

Re-arching the springs is the cleanest way to go about lowering a truck.

 

And then re-index the torsion bars to lower the front.

 

Cut bump stops to lessen the bottoming out problem.

 

Shorter shocks may be required as well, depending on how low you go.

Can the 320 torsion bars be "cranked" down like on the 620's? Or do they have to be removed and indexed? 

[Stoffregen Motorsports]

Depends on how much you want to change the ride height. The have a pretty fine spline so small adjustments can be made by re-indexing them.

O.K. cool. I just wondered because last time I was under the 320 I don't remember seeing that same double nut on the adjuster like on 620's , just a bolt if I remember right? I'll look again. It made me think bake of the days of removing the trailing arm of VW's and rotating splines to raise and lower so I thought maybe on the 320 you would have to remove the torsion bar and reindex. Please correct me if I am wrong as far as using the term re-indexing to refer to removing and rotating the torsion bar as opposed to just cranking on the adjuster. Thanks as always guys🍻

Yeah, re-indexing is when you remove the torsion bar from the spline and rotate it.
