PRG Advanced Coil Over SPC vs Coil over kit.

It has been a few months since i did a 2 inch lift in my truck and i am very happy with everything so far but at the same time i feel like i need more. Currently i have Bilsteins 5100 in the Front and a Single AAL in the Rear.

I have ben looking at the PRG packages and am interested in the Advanced Coil over SPC and Advanced coil Over kit. They seem fairly identical with everything expect the Upper control arm.

Can Someone shine some light on the differences between the 2? its a 200 dollar difference and i want to know what i will be gained going with one over the other. My goal is to be around 3 inches of lift.

link for the kits are here in case its needed.

The PRG uca uses heim joints and uniballs.
The SPC uca uses bushings and the stock ball joints.That is mostly the cost diference.
Both offer 3" of lift. I like uniballs over ball joints.I would spend the $200.
Centerline of wheel to edge of fender is a more common way to measure lift. Tire size does not matter this way.
Remember,cranking it up another inch will make your ride stiffer.

Going to a lighter spring will not make a difference in ride height. You would have to crank it up more is all to maintain the same height of a heavier spring. look up "spring rate",
Shocks have nothing to do with maintaining ride height.
Sprngs are what control ride height.To increase the height you need to compress the spring more which in affect increases the stiffness.
look up suspension geometry.Explains acf,motion ratio,spring rate,wheel rate,,sprung weight,etc.
I don"t know what I was thinking! I am wrong.The spring does not compress anymore at 3" of lift than @ 2.". Your droop decreases is all.
My bad.
