Yes it comes with about a 1.5-2” diff drop,  this is what the CV angles look like.

Hey, Pewterliftedz...  I'd love an update on your lift kit now that you've been running it for a couple months. Still no problems?  I am trying to decide between the RC and superlift too.

 

...one specific question.... How is the clearance between the lower control arm and the CV axle boot???? I don't see any daylight between the 2 in your picture... Does it touch at full droop or anywhere in between?

Hello everyone, im creating this post because there was little information about this lift kit when i was looking around. I have a 2018 Chevy Silverado 1500 Z71 and i wanted to lift it , but i didnt w

From what I understand they've made it so cv boots dont rub the LCA and looks like top balljoint mount for the UCA is angled so balljoints probably last longer.  However the new knuckle doesnt have st

Damn haha , well i already bit the bullet. I’ll see how long it holds. If its too much then im going to have to upgrade to a better kit like BDS or something that can correct cv angles as well as the ball joints. Thank you for your time I appreciate it

How's your lift holding up?

Lift kit is working great, I don't have any issues with it at all.  I'm actually looking into getting Eibach lift springs to combine with my bilstein 5100 shocks to replace the spacer.  I don't think I'm having any rubbing issues, but I'll jump under the truck and check it out when I get a chance.

Haha I know what you mean man, I'm tempted to just increase the 5100s up a notch to get a little more height.

I love the look of my truck dont get me wrong , but driving down the road and seeing the same truck in a 5 or 6 in lift running 35s looks so bad ass . I’ll make the decision when my tires get worn in the next 5 years lol and see if i would go taller and just slap some 35s  as well. Also i put back the ORM rancho shocks in the rear , rides little better in the back. You have a really good setup with those shocks too. I just checked my cv boot looks good as new ??

I decided to go with the RCX 3.5" knuckle kit because of the timing of things. I leave for Big Bend National Park Monday morning. The Super Lift would have arrived sometime next week about halfway through my trip.

 

Angles look pretty good to me, but I'm no suspension expert. Lower ball joint clearly has the most "angle", but it looks like it has plenty range of motion left. CV axle looks great and there's plenty of space below it for articulation. 

 

I will say, I didn't buy RCX struts. I hope to slap some bielstiens (maybe something else) in there and the back too. This is my first lifted truck and I'm very happy with it on day one. The ride is definitely harsher, but I'm hoping the bielstiens will bring it back closer to stock ride quality.

The kit was $500 and the install was $700.  There is some, but minimal cutting involved in the installation.  

 

According to Rough Country, when running the stock 20x9 +27 wheels you must use 1/4" wheel spacers or the tires will allegedly rub the control arms. I did not verify that. 

 

I did add 1/4" wheel spacers essentially making the tire and wheel package "fit" as 20x9 +21 wheels. Obviously, the stock 275/55r20 Goodyear Wrangler SR-A tires fit just fine with days of clearance all around.

 

I'm currently sitting at Discount Tire getting 33/12.5r20 (approximately 317/50r20) Nitto Ridge Grapplers installed.  These are slightly larger than Rough Country's recommended MAXIMUM tire size, 285/55r20 (32.3/11.2r20)

 

I'll update y'all on any clearance issues when I'm done here.

Discount tire wouldn't reinstall the quarter inch spacers because they weren't bolt on type...  They said the lugs were "shortened" with the sandwich in spacers. No hard feelings, gives me an opportunity to check tire clearance without the spacers. 

 

No spacers on stock 20x9 +27 wheels, tires rub the upper control arms in the front. Loose about 1/4 to 1/3 of a turn of the wheel with the tires I selected. 

 

Since I had to take the wheels off anyway,  i decided to see what 1.5" spacers would look like. Turns out they look great!  They rub the tiniest bit on the plastic behind the front wheels at full crank. I figure I can snip the plastic back just past the screw and run a screw into the fender liner to hold it back. Should give plenty of clearance for articulation under full crank.

How's everyone's lifts doing? I bought a 2018 Sierra about three weeks ago and have been looking into lifts pretty much ever since. Too much to decide on! I'm on a budget, but I'm willing to wait if something will last longer without needing repair. Thanks!

I decided to change up my Superlift kit, got rid of the front lift spacers for Bilstein shocks and Eibach 2.5" lift springs.  The control arms and diff drop still work great, it's a great kit that is very well put together.  Here is what I did to modify my kit if you're interested.

      This video may not be the exact content for the joke thread but its a lot of laughs so here it is, I've only watched a portion of it so far but if anyone is looking for some light hearted good soap box driving action, its here. As a note in the upper left of the screen it shows the number out of 100 to refer back to any particular vehicle for comment !.    https://www.facebook.com/reel/1351928276956715

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.
