So far I only see 1 front level "approved" by the manufacturer for the AT4 -- Rough Country SKU: 1318.  

My dealership has 3 leveled AT4s on the lot, and states the level kit will remain under factory warranty if installed and aligned by them for $875.  I am yet to verify this part number and take measurements of the trucks on their lot (I am away at work for a couple of weeks), but the parts department just stated they are using Pro Comp part number 63235, a 2.25" level.


Any thoughts?

I have read this thread front to back a few times. It looks like a lot of you guys have the Trailboss or AT4s. I have a RST Without the Z71 option. I want to do a 1 1/2 front kit, but I am not sure which one to get? Which one would be better for me, the upper or lower kit? Also any links to the correct kit would be great.

Here is the link lower strut spacer. 1.5" easier to install than the top spacer.

2.25" for the AT4 or TB...I say would be too much. Their has already been one case reported here with clunking noise on a 2" level spacer.

1.5" has been ran from several for at least 5K miles with no issues claimed so far.

Thank you! 

I think I am leaning toward the Rough Country 1318, and will allow the local accessory shop to install and pray for no issues or warranty battles.

I called Motofab for their opinion. They advised me to use the CH-2 kit which is a 2" upper kit. He told me the kit you linked is for the Trailboss. 

 

I am not really worried about which one is easier to install since it will be installed on a lift by a mechanic. I just want to make sure I get the correct one installed. 

 

But thanks either way.

Has anyone considered leveling their non AT4/Trailboss by installing a front shock and spring assembly from an AT4? 

 

In other words, I bought a guys slightly used AT4 front struts and am going to install them on my 2019 SLT 4x4. 

 

Think I can fit a 285/65/20 on my stock 20” rims?

I just got off the phone with the Pro Comp technical support rep, and we were just discussing this.  It should work.  For the record, we were discussing because he said the taller struts are the reason Pro Comp does not recommend their 63235 level for the AT4.  He was amazed to hear my dealership is installing and covering under factory warranty.

So can someone explain to me the difference between the trail boss suspension and the at4 suspension.  I thought they were exactly the same but according to rough country they are not. Just curious.

Very weird to hear that Motofab instructed you to use an upper kit, as the only kit shown for the AT4 / TB on their site is the lower mount 1.5".

As was posted above. I have a RST without the Z71 option. So according to Motofab I would use the upper kit.

Ahh I missed that part.  I bit the bullet.  1.5" Motofab lower mount for my AT4 and 295/60/20 Ridge Grapplers on factory 20s.  I will install level Monday then bring to tire shop for tires and alignment.  Update afterwards.

Yea. That what I was thinking.  I made a comment on there website saying "aren't the trail boss and at4 suspension the same."  And they responded with "not exactly".  I don't think they have a clue.

Following up on my earlier question about using an AT4 front strut assembly to lift a non AT4 4x4 SLT truck...I have done it and here are the results. 

 

Front suspension - stock AT4 strut with 3/8” aluminum spacers under strut on the lower control arm. (I made these on a lathe)

Rear suspension - 2” block kit 

 

Tires - Nitto Terra Grappler 285/65/20 on stock 20” wheels.

 

This set up has no rubbing at all and has not yet required me to do any trimming.

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      Parking Brake - Automatic Engagement Questions

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!
