KING extended shock question.

[SilverSlugger]

Okay so ive been wanting to upgrade suspension. Came across this pair https://www.carid.com/king-shocks/o...ilovers-mpn-25001-386-ext.html#specifications.

What are the differences between extended and "normal" for these King's? Does this mean that they will have a stiffer ride on a normal road? Do I need lower control and upper with these extended ones?? If I'm using the truck 80% on-road and 20% offroad should I pass these up due to them being the Extended versions?

Chances are these are the same as the ones you ordered. Put simple any aftermarket lift or leveling kit(not spacers) will have an extended travel compared to stock.

the extended travel require upper control arms, but technically you would be alright if you installed them and didnt do hard offroading right away id imagine. but they have more travel then the stock uppers can handle. hope this helps.

Looking at the product page again it is simply a 2.5 or 3 inch leveling strut assembly. With that said if it is at 3 inches then yes an upper control arm would be necessary but if not then not really. How do i know? I have the OME kit and it raised the front by 2.4 inches and I'm still running the stock control arms with no issues and I do go offroad regularly.

the extended travel part is where youll get in trouble if you full flex the shock your upper control arm joint cant do the same travel and will cause issues, ive asked stage3motorsports the same question. but if your trying to buy the extended travel and upgrade the UCA later i think you would be fine if you didnt full flex your front until you did. my 2 cents.

Thank you for the input. I'm leaning on going with the cheaper and "normal" Fox setup as im worried these extended ones will be more than I need. I've never upgraded suspension on any vehicle so there was and still is a lot to learn...

It seems like there's so many options and paths to go down. Also the price points of different brands differ more than almost any piece of equipment of shopped for.

Kings will probably be pretty stiff too. I was looking at them originally till I learned they wouldn't be the best option for trail riding. Most 2.5 shocks, king included, are meant for speed and jumps which they would need to be pretty firm for.

Sadly this is incorrect, any progressive valved shock will be superior to a digressive valved shock at both low and high speeds.

edit: the larger diameter shocks allow for larger internals/externals (i.e. shaft diameter), the increased volume also allows a higher fluid capacity which translates to more motion being necessary for the oil to heat up. When the oil heats the viscosity drops and you get what is commonly referred to as “shock fade”.

Kings description says they're ready to bolt on to a stock truck. To me that says that you don't have to replace the control arms. But I could be wrong. Really your best bet is to email King and ask them. They should be able to tell you one way or the other.

The only reason to replace the upper control arms is if you plan on lifting the front 2.5" or higher. Also, replacing the upper control arms can allow for up to 35% more travel which will take advantage of the extended length shock.
