Could you just RUF one side, similar to how you did the virtual lift?

Err, no.

I've VL'd the front both sides, just not the rear.

Sorry bout that Damo..

just drive it you fat bitch

The only real way to fix the sierra lean is to get a 3rd biggest leaf that is slightly thicker and use that. You dont need any more leaves on the drivers side like some people run.

Adding an extra leaf just makes that side stiffer and it wont flex as well.

Re-setting the drivers side pack with more arch will fix the leaf but it will eventually sag and the lean will come back.

The thicker leaf gives it a slightle high load rating but its not enough to limit flex. I ran my sierra like this for 4 years and it never developed the lean again but still flexed like a bamboo shoot.

Full or half RUF.
Have you done it yet? If not just push the front hanger forward a bit

How many leaves in the front pack did you run?

The springs I have are 3 + overload. I've taken the overload out which leaves me with 3.. err, leaves.

So you'd change out the smallest leaf for a slightly thicker one?

I have never owned a sierra that leans, if I did I would not consider runing more leaves one side than the other that is crazy.

I set my DS front spring hanger 8mm further forward to try and help the lean. now my shackles are uneven and it annoys me ever time i see it.

I was interested to note that the 2012 Nissan GT-R runs different spring rates right to left and even different suspension pivot points on each side due to one side being heavier than the other.

I'll stand by running a heavier spring rate on the heavy side being an acceptable fix. If you think about it, the heavier side will impart more force on the spring when it encounters a bump so if you have the same rate left and right the right hand side will compress more.

The only way to have the right and left side compress the same amount when encountering the same bump is to run more rate on the right to compensate. More camber will correct the lean but will compress more readily.

Exactly my thoughts!

I'm in the process of doing a RUF conversion and currently have my leaf springs apart for a service. The driver side spring has 20mm more camber (arch) than the passenger side. Will that be enough?

The only perfect fix is to transfer as much weight to the passenger side as you can. Think of this when placing batteries, spare tyres, compressors etc.
