Which would you recommend of each?
Why shocks, if front lift is just 1 inch. Thanks???
It all comes down to what your end goal is and what your budget is. The first question you need to ask yourself is "are you happy with how your truck rides, is it to rough"? If you want a smoother ride you need to automatically eliminate all spacer lifts since the truck will still remain stock ride quality. As I mentioned earlier Thuren makes new coil springs with softer spring rates, this will raise your truck while also improving ride quality (truck will ride softer). In my opinion the stock shocks are pure garbage and its just a matter of time before they start leaking, this is why you should change them. It also sounds like you will not be doing the install, so if your paying someone to swap your springs or add a spacer they might as well change the shocks at the same time. You have to remove the lower shock bolt anyways to remove the coil springs, your literally one bolt away swapping your shocks. There should be little to no additional cost to swap shocks while installing different springs or a spacer.
The spacer is the cheaper option and works for a lot of people. This is the option for those who simply want a higher truck. If you spend any amount of time off road I would purchase new springs vs a coil spacer. However, if you mainly drive on roads then you can consider this. The only off-roading my truck sees is parking at motocross tracks, very minimal off-roading so the spacer works fine for me.
The video above is a bit misleading in my opinion; they are literally bashing spacers trying to persuade you to purchase their coils. The funny thing is many of these aftermarket coil companies manufacturer spacers for the rear of the truck, I'm sure someone on here can explain why spacers are ok for the rear but not the front? Also, many people report when you add spring spacers this causes your stock springs to bow. I will not argue this but on a 1 in lift the spring bow is nearly identical to stock, maybe if you install a 2 in or 3 in spacer the bow gets worse, I honestly dunno?
Here is a quick overview on my recommendations.
Endless Budget: Thuren 1 inch or 2 inch coils with Thuren valved Fox shocks. You can purchase all of these parts from Thurens website. If you decide to purchase 2 inch coils vs 1 in make sure you get the Thuren track bar. When you raise or lower a vehicle this causes the axle to shift from side to side. With an adjustable aftermarket track bar you can recenter the axle. Carli is also another popular company but they do not offer a 1 inch lift option.
Limited Budget: Spacer lift of your choice and shock selection of your choice. I like the traxada spacers and the Bilstein 4600, 5100, or FOX IFP shocks.
