Doubling up lowering blocks? Safe?

[griffo20022]

Hey guys how are we? A while back I lowered my 340 3" both front and rear and tbh i'm not entirely happy with the ride height i'm still at and considering going lower, possibly another 2" (so 5" in total)

The 3" blocks alone were custom made let alone any 5" being available off the shelf? So i'm wondering if it's possible to stack lowering blocks one on top of the other if it's safe or not? Spose if they could be welded together if needs be? Is there any alternatives to lowering the rear axle other than the blocks?

As for the front I think i'll have the hub moved up the strut so I can retain some spring movement lol!

This is how it sits 3" all round, front looks higher as I have lower profile tyres on the front.

Have you though about having your springs decambered? Mine are done by 2" on the Anglia & it lowers it nicely without having your axle too far from the springs which would effect your scrubline.

*edited cos I'm a muppet*

[griffo20022]

Arrr that's a good idea, I've heard about having springs de-cambered and never clicked as to what it meant until you've just mentioned it lmao! I know theres a well known leaf spring company near to me that should be able to do it so i'll give them a bell, nice one dude!

[TerraRoot]

You can, but you shouldn't.

the longer the lowering block the more leverage the axle has on the leaf, lots more axle tramp when you put the foot down. oh and scrubline.

[bortaf]

I would say no, there's a reason 3 inch arnt widely available let aloan 5, the leveradge on the blocks is bad enough with 3s but 5s?
dam must type faster ;D

[stueyt]

Why double up the blocks? Why not just make/buy a set the size you require? If you are not going down the route of de-cambered springs. Just had another thought does anyone make a single lef conversion for your car?

Cheers,

Stu.

[griffo20022]

Nah it's cool, check my reply above, I shall look into having the springs decambered Whats a single leaf conversion? One leaf each side of the axle or on leaf for the whole axle? It's already on single leafs each side anyway

Thanks for the input guys

It may also be possible to mount the axle on top of the leaf spring. I don't know my 340s very well and am instantly assuming the axle is mounted below the leaf as standard

[kapri]

If it's on single leafsyou won't be able to have them altered , they are known as parabolic and have a taper when viewed from the side . They are not designed to be reused/ altered due to the manufacturing process, doing so will result in it snapping at some point.

Just take the springs off and weld all the axles directly to the body , for a truly low ride , remove the tyres to be the coolest kid on the block

If he's adding lowering blocks between the spring and axle to lower it then the axle must already be on top of the spring !

You are indeed correct MrSpeedy the axles already above the springs. Hmmm that's a bit of a curse word then if the springs can't be altered, may just have to leave it as is and see what the arch gaps like once i've spaced out the rear wheels, may have to just lower the front an inch and get some nose down on the go lol! I don't really wanna be doing anything too mad to get it low as it's sposed to be my runabout and already messed with it too much lol! Can't help it lol!

[skinley]

How about getting leaf springs from a different car, then have them de-cambered?

[Mystery Machine]

I doubled some up but didn't want to risk them moving about to got B8D to wled them up for me. Easier than making your own and more secure than just having them stacked.



He also made me some longer U-bolts to match - this shows the new U-bolts against the old one


.....and then threaded

[wagoneer]

^^ now that's just clever ^^

I'd still be interested in decambering the springs if it was me. Very tall blocks just feel a bit, I don't know, not right. I'm thinking of lateral movement and stresses here and am no engineer so please anyone feel free to shoot me down!

[Dez]

as has been said, its not a good idea. plus, 4" is the absolute scrubline limit on a 340 so 5" really wouldnt work.

[purplevanman]

sorry but dumb question time......


whats scrubline?

cheers

Seeing the 340 has a DeDion rear axle is that going to cause problems with drive shaft angles unless diff is raised as well ?

Hmmm not too sure, I hadn't even thought about the driveshafts tbf so good point lol. Wouldn't be able to raise the diff any higher anyway as it's bolted straight to the floor anyhow.
