Aftermarket coils necessary with 5100s?

That looks good. Are you running 265’s

 

I’m confused, if it doesn’t preload the spring then how do you get lift?

 

Magic bro.

 

There are a lot of claims for the 5100 shocks.


People say when you increase the perch setting you are "preloading" the springs. I don't know if the term preload is just thrown around, but regardless it is the wrong term when it is usually used.

When you adjust the perch setting on the shock, you are not changing the spring rate or the total force applied, so the spring will always compress the same amount -- moving the perch only changes the position of the spring seat (making the truck taller or lower), not the "preload" on the spring.

 

Here you go... had it saved.

 

You can always tell who just mall crawls and who actually off-roads over these debates.

5100s + stock coils + upper notches = preloading the shock = limiting downtravel (potentially damaging the shock as it over extends).

cool, if you’re just doing it for looks and stay on pavement where you’ll never notice it. Not cool if you want to retain performance off-road after a lift.

to each his own, not talking shit - simply the facts. You get what you pay for.

 

I have the 5100 with stock springs at highest setting. It was a budget choice, and I really appreciate it. My stock shocks were leaking, and it is a HUGE upgrade from that. Ignorance is bliss in some cases, and you got to know what you ride. I do 90% city, 9% Fire service and 1% sketchy. I will not over extend them, and won't need them to perform beyond what they are completely capable of.

If you want to wheel, baja, or blast FS roads, and not feel it, you really should get another set up. If you want a budget lift, plus an upgrade from stock, you may find this works.

With that said, my next setup will be OME + Coils + Nitros because I would like to keep the lift + have the ability to add a bumper.

 

When you put the spring on a higher perch, the perch and top hat are closer together, therefore compressing the spring... aka preloading the spring.

Preload is a measurement of how much a spring is compressed at full extension of the shock.

 

Okay, thanks.

 

Yes

 

Yes!!! This is correct! I don’t know why everyone else is talking about the spring being compressed more. That’s incorrect.
