14 Silverado Icon 71555c & Dirt King UCA Installation

Madcow2020 · March 24, 2017

Silverado with Icon 71555c GM shocks and Dirt King UCA Kit, all bought from MRT (Great Vender)

I'll start with the Dirt King UCA. They rock. The UCA is solid and beefy, and the alignment shop had no issues getting a good alignment on the truck set at 2.5 inches of lift. The Dirt King UCA shipped fast and arrived packaged well.

There does sound like there is a piece of slag rolling around inside the UCA, but I have not heard it from inside the cab. I wish they would of drilled and tapped a hole on top of the UCA to relocate the ABS Sensor cable. It would of been a simple enough modification. I cut the locator tabs off of the factory ABS sensor cable bracket and ziptied it to the UCA. I plan drilling and tapping the UCA when I have time.

The Icon Vehicle Dynamic 71555c shocks:

They are the 2.5 inch remote reservoir CDCV adjustable ( means you are able to soften or firm up the shocks). Install was pretty straight forward. They do not come with the directions, so I had to download them from their website. The factory lower shock mount bolts have to be used. Keep them if you put a leveling kit. I was only able to find 3 out of my original bolts but luckily I had an extra from one of my past trucks. It was a little shorter but worked.

The tricky part was setting the ride height. If you watch the video on how to set the ride height for Icons it is good and accurate, but the four turns equal half an inch is not. The hardest part about getting the ride height set was getting a good reading of the shock mount to adjuster nut.

There is a bezel on the upper mount that makes it a little difficult if you do not have perfect lighting.

My recommendation is to set the shock to the highest setting with the tires removed and a good flood light. Once set at the heights setting and a good calibrated eyeball alignment drive it for a day and check the ride height. 24.13 inches from Center Hub to the fender is what they say will give you 2.5 inches of level over factory. Then get an alignment.

Driving impressions they are a 1000 times better than factory. I am still braking them in and seeing what I think. They have rally shown how poor the factory rear shocks are. If anyone want to send me a matching set for the rear I'll review and write those up too.

Oh by the way they like to say .827 inches that's 7/8 of an inch. So unless you want to use a micrometer.

MRT had awesome prices I'll be ordering some other parts from him in the future. Looks like a set of Matching rear Icons and a Dirt King rear shackle kit are in the future.

If anyone has any questions just ask, and I'll be updating as I have some more time to evaluate.

Thank you for this excellent and thorough review! This system is top of the line and we are excited to hear your impressions after putting a few miles on them. The install tips will surely help not only some of my techs here in Las Vegas, but members on the forum as well.

Thank you again for your business, and your patience as those ICONs did take longer than expected to build. In the end we know the performance and ride quality will be worth it!

Now it's about tuning. With some more overtime I'll be buying the Dirt King Shackles and Icon rear shocks to match.

Looks good.

I would not drill/tap the boxed uppers. Just asking for water intrusion or a potential weak point.

Looks good[emoji106] I think your coilovers are on the wrong sides though. Your fittings on the coilovers for the resi hoses should be facing out. Just trying to save you some trouble should you get one of the hoses squished in the coil.

That is how the instructions showed to put them in. All of the ones on their website are installed the same way. I was wondering about it also. I sent pictures of the install and questions in to Icon to see what they say.

Hey mods could we change the title and add the n to the end of the installation. If it is too long of a title please change the 2014 to to just 14.

I will say this MRT has been great and very helpful to get the issue fixed. I will update when there is a resolution.

So Icon has been really slow with their responses, and I will keep everyone updated on how it goes and will give a complete report on however it plays out.
