As some may remember when i bought my Sierra it had a very poor suspension set-up.
Had no flex, Was hard as a rock, brake lines were too short, shackels sat vertical, and shocks were actually 1/2" shorter than static mount to mount measurements!
On reccomendations from people on here, i have:
Removed some leafs. 2 from rear, 1 from front. It now has 3 at the back and 4 at the front. They still have the clamps fitted.
Fitted Hilux/commodore shock combination.
Fitted extended brake lines.
Extended front bump stops 2" (yet to touch rear).
Anyway, now flex has improved greatly. Softness has improved a fair bit too.
BUT ride is still a bit too stiff, and flex could be better.
Since removing leafs, shackle angle has slightly improved, from dead Vertical to about 5degrees off vertical. So still crap!
I took some measurements this afternoon:
Eye-to-eye of the shackles is 128mm
Eye-to-eye of the leafs (while sitting on flat ground) Front=900mm Rear=1000mm (this was a straight measurement, not following the arc of the leaf)
I'd like some advice, to cheaply and effectively improve flex and ride. Preferably keeping the current leafs.
Such as, should i fit shorter shackles? If so, what length would be advisable?
Could i remove another leaf from the front? So i have 3 front and 3 rear?
Thanks in advance, Here are some pics of flex
