Even if they fit the tire.. doesn't mean it doesn't rub

You probably won't get much response, because that question has been answered dozens of times...and members expect the new guys to search for their answers before asking a common question.

 

I'll give you the short answer...Yes, your truck has a 1.25" rear block, so replacing it with a 2.25" block will give you 1" of rear lift total. And yes, you can run a level kit in the front (and your combination of bilstein & spacer will be fine as long as you don't go higher than 2.5" total). I did something similar on my last two trucks. On my 2009, I ran a 2" spacer in the front and 3" blocks in the rear. Factory rake was about the same (which was nice for towing), but the whole truck sat 2" higher than stock. Then, on my 2012, I ran a 2" front spacer and 2" rear block. That truck only had about 1" of rake, so I added Timbren SES (with 1" spacers) to the rear to help with squat when towing.

 

And, if you tell me your rim size, I can help you with tire sizes...

 

Big Whiskey, Thanks for your help, lots of information I just wasn't sure I was reading it correctly. My wheels are stock 18" with p265/65r18 goodyears. thanks again for your help.

I did find this information from a previous post. Sounds like this combination of 5100 Bilsteins and spacers will get me where I want to be.

 

 

"Front - 2.5 inch (combination of bilstein 5100 set to 1.25 and 1.25 top spacer)

Rear - 1 inch (replaced 1.25 stock with 2.25) w/bilstein 5100"

 

Not sure how the rear1" was actually accomplished - Does the Silverado 1500 come equipped with a 1.25 inch spacer? top or bottom? Thanks again for any input.

I'm running similar setup on my '14 HC. Except my 5100s are set to highest setting (1.8") with a .5 in spacer on top in front. And swapped out stock block (1.25") for 2.25" block in rear also with 5100s. Running 295/60/20 on stock high country rims. Barely rubs, and I mean barely, inner liner at full lock. Sits about 1/4"-3/8" higher in rear. As Big Whiskey stated, you can run bigger Timbrens or Firestone Airbags in rear to help with squat while towing.

How bad is that rubbing the UCAs and swaybar?

Im not rubbing on the UCAs just on the sway bar. "How bad?" Just enough to notice it when im doing a turn at full lock. By that point i give some slack on the wheel and proceed turning.

Anyone running 5100 bilsteins with a small front spacer? with or without the rear block? Anyone with this setup please shoot me a message.

 

My plan is 5100 bilsteins set @ 1.5-1.85" and a 0.5" front spacer along with the 2" rear block to maintain SOME rake. Bilsteins are ordered just scoping out what I should couple with it

 

thanks ina dvance

Any suggestions on this route, would you do it again, would you opt for anything different? Any issues?

 

I think I'd like slightly more rake than you show.

I'd do it again every time. The ride is tremendously better than stock. This is the only route I would personally go without a lift. I've done the RC 2" level and TGC 2.5" level on trucks I've owned, the billstein combo I put on here is the sweet spot IMO. Works best for me. If you want a little rake, put the fronts on the 3rd setting and you should be all set. Edited by bwilloby46

Did you try the different settings? Will the bilsteins act better at a lower setting with a larger spacer or the opposite?

I did try the 2nd setting before the top. A little stiffer ride on top setting that I noticed but that's expected as I added 10ply tires at the same time. My opinion avoid the lower spacer with the 5100s if you can since they are designed for height adjustment. Anything over 2.5" your at higher risk for premature ball joint issues. All depends on how much clearance you want Really.

Definitely. I'm thinking 0.5-1.25" top hat with the 5100s. I have the shocks ordered. It's just a matter of adjustment w/ installation now.

 

I have to get a front and rear spacer as well, considering the rough country kit and selling the 2" lower spacer.

    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.                  
    • drive the truck back to the dealer and complain that the button works.

    • I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip. 
    • Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
