Hey guys I have a 21 Tahoe RST 4x4 i modify, lift, lower & repair cars for a living along with alignments body frame & advanced driver calibrations. Please pay attention if you have already lowered your Tahoe and I’ll explain why you’re having drivability issues.
With that said stop taking your front springs and putting them on the back. I did this and it makes the truck wander on the highway yes it’s get the lowered look but this is very unsafe considering the trucks reaction to hard cornering and or braking. Everyone that’s already done this is just to proud to admit that it drives like a boat on the highway. Just do it right Belltech has adjustable shocks that utilizes factory springs for 100$ a piece we all want to see you and your family get home safe.
I’ll post some pictures of the install and part numbers for struts/knuckles alignment specs feel free to ask any questions and I’ll get back to you. 305/30/26 fits with no rubs I can also help with pre setting alignment angles before you take the truck to the alignment shop after lowering.
One more thing i’m sure everyone has noticed the front wheels sit back towards the firewall this can be fixed by adjusting the alignment cams on the lower cont arm —the farther the lower ball joint is towards the front of the vehicle the higher the caster angle will be this fixes the setback look and brings back drive ability after lowering this is a must if your install larger wheels and tires. ( Give me a few days I’ll post pics of my alignment cams clearly marked with instructions if you would like to try it yourself or just pictures to print off for reference to give your alignment guy. Unfortunately most shops will just want to do a tow set and blow ya out the door so keep that in mind.

Setup:
Belltech adjustable struts 25019/25022
K2021SUV225
RST replica wheels 26x10 eBay
305/30/26 tires

your truck looks amazing!! The way that sits on those 26’s is tough!!! Great work man! Thanks for the lowering info! I always felt uneasy about taking the front springs off and putting them in the rear. This is great info!

I like it!! This is the route that I've been researching. Glad to see that there's some verification to what I was thinking. I do have some questions.....1) can you offer up the spacer configuration that you used (i.e., what was the total drop front and rear)? I didn't see that info, so if I missed it, my apologies. 2) I'm going with 26's, but have been thinking about adding spacers to push the wheels out a bit more. I've read that some 26's actually need the spacers to clear the caliper, but that would obviously be based on the offset. I've also heard/read about spacer issues. I had hubcentrics on my M5 (tuned to over 800hp) and never had an issue at high speeds.....and there were plenty of data points for me to choose from. ;) Granted the Tahoe is a much different car, but wondering how much space you have to beef things up a little more. 3) Any feedback on tire wear? I've been a fan of the Accelera and Ohtsu tires, but the Lionhart's look good, too. Very similar tread pattern to the Accelera (probably made by the same people). They're unidirectional, so you can rotate them accordingly. TIA!!

Nice work on these badboys! I have a 21' burban, I just ordered some 26s. But it definitely needs to be dropped. I called 4 local shops in my area (Miami, Fl) and all said there are no kits available for this vechile. Only 1 shop said there are, but only for the front but nothing for the rear. Luckily, I stumbled across this page! Honestly speaking, I don't know shit about shocks, springs, parts, fixing or nothing. I'm super lost. Can someone please guide me on what I need to order to get a clean, even/leveled drop. Idk if I need a 2/3 or 2/4 setup. But I really like the first pic of the white Tahoe rst with the 26s. That's the look I'm going for. If anyone that can help, I'd highly appreciate it. I have a 2021 suburban rst 4WD. Thanks!

This is all you need. I have a '22 RST Tahoe and this did the trick.

Final product looks amazing. I just threw my 26s on there. Now I need to drop. So if I'm reading your post correctly. All you did was change the 4 struts and semd for an alignment. No other parts (springs, etc) correct?

Cool, so basically just the 4 struts right? #25019 Sierra struts for the front and #25022 for the rear. No shocks or other components? Can you please post some pictures!
Yes that's all you need. Ends up being around $500 plus labor and a new 4 corner alignment

Did the 26 change your ride quality? I just threw brand new 26 with 305 lionhart tires and it vibrates some. I think it's that one of the wheels isn't properly balanced. And issues with yours?
