YJ springs your opinions please SPOA or SPUA

Post by gp7186 » Sun Jul 14, 2013 3:27 pm

Right im about to fit anus yj springs to my sj but im unsure whether to go SPOA or SPUA. I would rather go SPUA but im unsure if I will have enough clearance between my sump and front diff as its fitted with a 1.6 16v engine. Has anyone ever had this trouble before

Thanks gaz

SPUA should be fine. Standard YJs give a little lift anyways and i'm fairly sure they sit the axle a bit further forward too.

Sure Scotie will confirm all when he sees this.

I run YJs with spua and a 1.6 8v with the vitara sump and have no issues but my engine is raised slightly.

It should be fine but if it does hit the diff you can always fit a 1.3 sump with modded pick up pipe.

Thanks thats a bit more reassuring. I suppose I'll just have to see how it looks when I fit them. Im currently running standard sj springs with add a leafs SPOA and ive grown to hate the extremely harsh ride. I am also beginning to hate the massively lifted look, I now much prefer the look of scotties sj looking nice and stable with more than ample flex and clearance. I already have done a virtual lift with extended landrover arches .

Cheers :doublethumbs: she does flex pretty well on the YJs, think I could get more with longer shocks as well

I think you'll really like the stability of being a bit lower, I don't think I have actually felt like I'm going to tip over yet since fitting the YJs and samurai axles :thumbup:

Thanks for them pics shes looking awesome as usual have you thought of running missing links. I use my sj on the road and am concerned about them opening up round corners perhaps I can make them with removable pins to stop this but still allow them to work off road.

Thanks :doublethumbs:

With YJs I really don't think missing links are needed, personally I don't run them just because I think the suspension is more predictable without them.

my shocks have 9.5" travel and I think I could get another 1.5" of extra droop without them fitted.

Right ok what I think I'll do is fit the springs then measure up for shocks to allow for maximum drop also replace the front standard shock towers whilst im there

I also had to raise the rear shock mounts 3" for mine, you could get away with just titling them in but that reduces the damping of the shock. I also mounted my shock to the axle instead of lower U-bolt plate though, reason for this was that when I buy longer shocks I can then mount them on the lower U-bolt plate so that they won't bottom out. I raised the whole rear bed to do this but there are plenty of other ways to do it.
