I have a 2008 Sahara Unlimited with hardtop and I added a Rough Country BB which is 2.5" in the front and 2.0" which should have leveled it out but with 100k miles the front springs are sagging quite a bit. My question is, I see springs for sale with different numbers on and would like to get the tallest/stiffest factory spring for the front. Anyone know which ones would do the trick????

 

Looking for last two numbers on tag. Fronts range from 14 to 19, rears 54 to 60. Higher the number stiffer the spring

 

Kh202 is on point with the exception of Rubi 10A springs. They are longer and their numbers restart lower. I don't have a range on them but 06 and 09 are a couple I've seen floating around. You'd have to open the parts catalog to see what the numbers are.

 

So are the 18/59 the tallest front springs avail??

The 19/60 combo is the stiffest factory spring available,

 

68196006AA-front
68196009AA- rear
Off 10A Ruby, are 1.5" taller than a standard 19-60 set.

 

No and no. The 10A rubi springs are the stiffest available. The uncompressed height of +1.5" over the 19/60's doesn't mean much since it's all about spring rate that makes the difference, not the number or length of coils.

 

Are these for sale???
