That doesn't sound normal, mine handles bumps just fine.

 

It doesn't happen over must bumps just certain ones. It's extremely hard to try and describe which bumps do it, I think its when the shock goes down and the body of the truck goes up. and being that the shock is pretty much stretched to the max theres no way for that shock to absorb it. if you can picture that. Did you go with a bigger tire?

 

Yeah I cant imagine that is normal. However you now have me sweating bullets lol. I just purchased the 2" Rough Country lift myself, but have not installed it yet. Keep us posted if you figure out what could be the cause.

 

The cause is that the 2inch spacer they installed has expanded the shock to almost its fullest, there's almost no absorption when the truck goes up over a bump its the recoil I guess you could call it when the truck comes back up

 

Yeah, I've been running larger tires since before the lift went on. I still have plenty of up and down travel in the front with the lift.

Did you change the shocks by any chance??

 

Functionality is a major trade-off for looks. IMO...

 

I couldn't agree more

 

What size tire do you have

 

225/65r17.

 

I have a 245/65/17. Maybe that is causing the issue

 

I do believe that larger footprint may have something to do with it. Can you drop down and test with some 225 or 215s🤔

 

I actually just ordered the 1and 1/2 inch spacer kit from daystar. Gonna try and swap it with the 2 inch kit and see if the 1/2 makes a difference. Silly question but how can you tell if your patriot is FD1 or FD2 ? I have read the FD2 is already an inch higher then the FD1

 

If you have FD2, you have a CVT, and you'll have an "L" and "Off-Road" below D on the gear shift bezel. You'll also have front and rear tow hooks, metal skid plates under the engine and gas tank, and a height adjustable drivers seat... among other small things. But I'm pretty sure that FD1 and FD2 were at the same height on 2011 - 2017 models.

 

FDI has the "Auto-Stick", FDII doesn't.

 

Humm I also have this hard bang over certain bumps! Mine is lifted 2" I'm putting mine down to failing shock absorbers... But haven't looked into it yet! Let me know how you get on with the issue. My wheels n tyres are 235-70-16.

 

Will do

 

Have you guys tried retightening the sway bar endlinks? I had trouble with mine coming loose.

 

No never have. But my lift is newly installed so nothing like that has ever come up

 

Mine also makes a loud bang going over big bumps. Only started doing it after installing new shocks and the stu coil lift.

 

It sucks doesn't it!! Lol. The sound it makes is bad. At least now I know that it just isn't mine. Wish I would have knew about this little nuisance before I installed the 2inch kit..

 

The shocks on these patriots in my opinion can't take a 2inch lift ( if you want it to always ride like stock). Wish they made a longer one for us.

 

Swapped the 2in lift for a 1 and 1/2 inch lift, problem solved..

 

Same boat. 2" RC lift and it hits hard over some bumps not all. I got use to it honestly but it does freak you out when it happens. Concern always is that without that extra travel 'space' on the strut. could it be causing more damage then good.

 

Exactly, I bought the 1and 1/2 inch daystar kit and had my installer just swap out the front 2in spacers for the 1and 1/2 inch spacer and leave all the stuff from the RC lift in the back. looks pretty much exactly the same and the noise over certain bumps is completely gone. And I feel better about not hurting something else. Totally worth the extra couple of bucks for piece of mind.

Makes sense I honestly may do the same. Just sucks that I literally just took them off to put new struts in and have to take them out again

 

Very late to this conversation but I just had the Rough Country 2" kit installed last week. Looks great but I have the same hard bang on certain speed bumps. Tire size is 235/65R17 (Toyo A/T Open Country).

Question: Even with the extended strut from Rough Country's front spacers, would switching to a brand new Monroe front strut assembly potentially solve the hard bump?

Photos taken pre-alignment & camber adjustment by a good 4x4 shop.

An aside: After the RC install, I separately made two trips to Firestone Complete Auto for alignment. Wheels were aligned, but there was positive camber on the front end (wheels tipped out at the top) and they couldn't figure out how to get to neutral so I wouldn't burn my outer tread at a rapid rate.

You can see the front wheel tipped out at top. Camber bolt adjustment fixed it.

Since they don't specialize in lifted vehicle alignments, they didn't know what to do with the camber bolts that came with the kit and were installed on the front strut knuckles.

New camber bolt (Rough Country) is the shiny black one at top of the knuckle.

Took it to an off-road shop that deals and installs a lot of Rough Country kits, and he straighten out the toe for me like an expert. He also commented that he liked the new kit configuration with the rear lower control arms. Long story short, don't go to Firestone or any other retail alignment shop after getting your kit installed. A proper off-road / 4x4 shop that deals with a lot of lifts should know what they're doing.

 

Have the same problem with my 2" RC lift. Loud jarring bang when exiting a speed bump or dropping into a pot hole. I had the lift installed by professional 4x4 shop . They recommended the RC lift. When lift was installed it had the factory 17" all weather tires that came with the Jeep . The jarring bang was there with these factory size tires. Two wks later I had 245/65 17 A/T's installed . Tire size was recommended by RC. Still the same jarring/banging noise.
I intend to go back to the install shop to see what they recommend . In my opinion , it is either the shock travel or how the lift is mounted. But that is just speculation. Anyway , it needs to be addressed as I fear possible damage from the pounding .Or at the minimum I will have a rattle trap in short order
P.S. I lifted the Jeep for light off road use. Also install a class three reciever hitch for jet ski towing. I have been able to purchase the front and left gas tank skid plates and plan to install as soon as I get the mounting hardware. Unfortunately , the right gas tank skid plate is not carried anywhere. Anybody have one to sell?

 

Greetings all, this is my first post here.
I purchased a 2017 patriot in December.
I just put on a rocky road lift which I believe is 2 1/8.
I found this post while researching tire sizes that are available now with the lift.

just as a note to any installation at least with the rocky road lift….

they give you two bolts per wheel for the sway bar link extensions. I only needed to use one bolt in each wheel, as the sway bar link occupies the other hole.

I did note that it is important to make sure you install this bolt with the threads facing outward!!!, so that the threads do not hit the sway bar. ***

Other than that which is an important observation to make when installing, when removing all four wheels and placing in the space or Lift I noted that all four wheels are Struts. Not shocks.

since the spacers go on top of the struts and lift the body, there should be no additional strut travel within your struts.“When you guys are saying or speaking of “shocks” I’m not sure exactly what you mean?

regardless, there is no additional travel as the struts are Not extended or collapsed, you’re simply putting a plate above them.

I put in my lift and went to take it for an alignment. It sounded a little Clunky so I checked it when I got home and that’s when I observed how the bolts were Hitting against the sway bar. I could see the sway bar link was scarred from impact so check yours!!!! I also noted that one of my sway bar links appear to have been a little loose when I put it in. So I tightened it up. After that when test driving for about 20 minutes, it felt amazing quiet and tight as it did before the lift installed.

Just wanted to pass that along.

 

Well after living with the banging from the RC 2" lift. I contacted RC about it. They said that they have never heard of this issue (?) and wanted me to send them an audio of the sound! Well I wasn't quite happy with that response since it has been an issue that is posted on the web for a while now.
After a year of living with this teeth rattling bang I just purchased the RC loaded struts on Ebay . I haven't installed yet as they just came in today.
So, after purchasing the lift kit and having a shop (4wheel) install for around $750 total and now paying another $335 for struts , I decided to install myself (at least try). So cost for a 2" lift will be over a grand ! Not sure of the value there.
P.S. I also used RC recommended tire size (see RC site) for a 2" lift and the tires still rub. :/

You may want to look at Post #29 from HemiSteve. He seems to have solved the problem.
