Does anyone know which Rancho 9000x Part numbers I need for my truck?

I have a 2 inch lift in the front if that matters.

Thanks!

 

Are you dead set on 9000's? Bilstein 5100's are a 10x better shock, and they cost less too. I ran 9000's on my last two trucks and I'll never run 'em again....

 

Any specific reasons?

I will be sled pulling, I figured adjustable will be nice for street, strip, and sled pulling..

I ran 9000x's on my Ford F350.. Seemed to work pretty well..

Wouldn't you say my stockers are shot at 200k?!

 

Yeah, I'd say your stockers are shot......

Both sets of 9000's I ran rusted out, the adjustment ***** froze up, bushings rattled after a few thousand miles and just generally weren't that impressive. I got my first set shortly after they came out. The Bilsteins are just a higher quality shock and work pretty well in all situations without needing "adjustment". They're also about $10-20 cheaper per shock than the 9000.

The 9000 is a twin tube shock. Twin tube shocks are more prone to aeration in the oil and fade from heat build up. The oil and nitrogen aren't separated. In a monotube shock like the Bilstein or KYB, there is a floating piston between the oil and the gas (nitrogen) that prevents aeration and shock fade. You'll get better, more consistent dampening with a monotube shock. Monotube shocks are typically valved a little stiffer than twin tube shocks.

You'd be surprised at the difference a good shock makes over a mediocre (or worse) shock. I'd suggest the Kings but then you'd be looking at the difference between $70-80/shock and $325/shock.
