Put the notch in today and it's finally sitting at 4/6...so excited! Rides great, no bottoming out. Still need to modify the perches to correct the pinion angle, it's worse now since I put the lowering shackles in. Don't understand for the life of me what GM changed on this truck from the 2020's. Shouldn't have to modify the belltech kit to fix the pinion angle. Is what it is now, no turning back!

Still need to decide on a wheel but leaning towards a 24x10 Vossen HF6-3. Future mod will be C6 ZR1 calipers to match the blue center caps lole61a962f9eb0b6823d46dd91591a934e.jpg5d88ffe71aef835b1b130350d29b8813.jpg15abaf3de34cf7e3c71dfda3a93cb7a3.jpga1816af5fdfe50978e89cb066fa25910.jpg17595b348e40d1f119981125b311cdb2.jpg425add02177fae0d33255dc3372aa4b3.jpgbd49bf92b645803155c0e57c5bda79cb.jpgb8fca36e51db418aca15ae59b6ed1e60.jpgf8171228de3cebc4a7f3b642954ec4b2.jpg

If you or the shop disconnected the driveshaft from the axle, was it marked so it went back on the same way it came off? 
 

Was the driveshaft dropped hard in any way? Maybe it needs to be rebalanced?

So here is my 2020 Elevation I just lowered with 2/4 Maxtrac drop kit. For those of you that have lowered your trucks with a flip kit, how does your truck ride? What shocks did you use? Any vibration

2021 RST with Belltech set at 3/4.5, IHC helpers in the rear. I'm installing a Twisted Metalworkz weld in under bed notch on Friday so it can finally sit at 4/6. Helpers will be added back on so I can tow my boat.

Has anyone else had an issue on a 2021 truck with a bad pinion angle? I installed the Belltech 1041sp kit on my truck and the pinion angle was -10 degrees when it was done. It vibrated so bad I could barely get it to my buddies shop. We modified the rear perches to get the pinion angle close, but still have a vibration under hard acceleration. Once it's sitting at 4/6, I'll check the pinion angle and modify the perches for final to get the pinion angle 0. I called Belltech and since they haven't test fit on a 2021, they can't confirm fitment. Guess I'll be the guinea pig...it doesn't work outta the box lol. c47ad8d985685c9ea6dcce01a209af8f.jpgd247cdbbfb2a711ba8979a585327aad5.jpg2cc9262e3089a50f764a3149f76a4f46.jpg763949cd337589aaa1f1d0f46b463c5a.jpg

Hey man just wanted to know from your perspective how the belltech struts ride from the front ? Im planning to combine them with my IHC control arms for a 4” in the front. Had bad experience with drop struts in the past is why im contemplating. 
 

Also, why did you have to add a drop shackle for a 6” in the rear?

So far pretty good but I don't have a lot of miles on them yet. Before yesterday, the rear bottomed out so much that it was hard to tell how the front rode. It's stiffer than stock, but it's not bad. If I had my choice I'd put the Belltech double adjustable shocks and struts on it so I could fine tune the compression/rebound to make the ride better. The street performance stuff is definitely better than the old nitro drop crap they had years ago.

When I lowered the truck initially I was only going 3/5, so I added the lift shackles that come with the kit to get back up to 5". I was just gonna run the 3/5 with IHC helpers but the truck still bottomed out until you aired it back up to 4" drop....which seems pointless. So I decided to just c notch but I wanted a weld in instead of bolt in.

I think it'll ride firmer then stock on your IHC set up but not bad. Why are you taking the stock struts out?

I see that you still had bump stops along with the bump stop mount. I had the same issue were I was bottoming out after the install then had the bump stop removed and mount cut off. Currently running no bump stops and running 15 psi on the bags with few hundred pounds of tools and crap in the bed. I daily my truck and for almost a year now with the IHC kit installed, the axle kissed the frame twice on huge dips going 60 mph. At 15 psi it may have lifted it barely 1/4”. 
 

Reason for the upgrade is to get to 4/6 with adding in adjustable struts in the front and replacing the lift shackle with the stock one. Also some guys who replaced the rear shock with belltechs assumed that it rode better than with the shocks the kit came with.
 

Theres someone on forums who has the kit running 3/6 on 26s with no notch and aired it to 25 psi and claims that he doesnt bottom out so I may just chance it.

Yea, I left the bump stop cups there because I knew the notch was going in. Unfortunately the notch took some time to get here.

Once I get the pinion angle corrected, the truck should be perfect. The rear end is also shifted to one side a little more than 1/2", so it might get tight with the new wheel setup. I wish DJM would sell their flip kit separately, it gives you pinion angle adjustment and side to side adjustment. When I called them, they said they only sell complete kits for these trucks, they won't break out their flip kit. This flip kit would solve both my issues.

Just curious, exactly what parts are you currently running on your setup?

Lmk after installed and running it some miles. I was contemplating doing this as well. 

So, I had my front struts installed and had an alignment done. It is definitely a much more controlled ride, but there is definitely a stiffer ride characteristic that I am trying to get used to. The factory was so plush, it is taking some getting used to. I guess I had the same results when I lowered my '08 GMC though.

What ring setting is it sitting on ?

3 wide, 1 narrow, which is the OEM height since I used drop spindles.

Thanks for the info. I know what you mean by "controlled" ride which equates to stiffer. Ill probably try out bilsteins 5100. There was a member here who used them and claims that it lowered his truck by a little bit.

Update on my lowered suspension experience. The front Belltechs have been installed and the alignment done, and honestly I am not thrilled with the results. The ride is very 'busy', meaning that I can feel every dip, bump and imperfection on every road I travel. When I hit a dip in the road, my truck dives immediately instead of letting the suspension drop and floating over it like the factory suspension. Also, I am having the 'drive' the truck using lots of steering wheel correction to keep the it in a straight line. Here in Texas, the interstate speed limit of 75mph is more of a suggestion and I drive it 5 days a week.

 

This is the 4th GM truck I have lowered over the years and none have ridden this firmly. All were done with drop spindles, 2 of them were S-10s that already had the axle over the leaf and my '08 Sierra had drop shackles on the back with Street Performers all the way around. I don't know what I can do to make my truck ride better. I may wait 6 months or so for the sting of how much I spent lowering the truck wear off and then raise it back up, maybe just put drop shackles on the back. It's too bad, I love the way it looks!

I would agree with your take on the ride. In my area there is a 1.5 miles stretch where the truck is constantly bouncing and it drives me crazy. I was in my wife's brand new Jeep GC Limited and it rode the same, bouncing a lot,, so the rode definitely sucks. But I'm coming from a 2017 Ram with Ground Force coils, which rode like garbage. Then a 2019 Ram with Maxtrac struts in front and coils in the rear, which rode a little better. This truck with the Belltech SP's definitely rides better then both of them by far.

I think the only real solution for a better ride is using a double adjustable strut/shock setup. Viking and Belltech have double adjustables but I don't know if they have anything for the T1 trucks yet. Unfortunately that's not a cheap route to go. But I think having control of both compression and rebound will allow you to fine tune it to where the ride would be far better.

I'm in it for the long haul, this truck is staying lowered forever, especially after all the work I've put into it so far. I will keep the current Belltech setup for a year or so, then start looking to see how I can switch to a double adjustable setup. Always improving lol.

This is my current situation, truck is apart in the driveway with snow all around it, while I modify the leaf spring perches to correct the pinion angle. I'll slow down on the truck after I get this vibration taken care of, hoping the pinion angle correction is the answer. My neighbors must think I'm crazy, brand new truck apart in the driveway, in the middle of a Michigan winter! Lmao4e91dfbb96d66617c34939f5fd3e3d42.jpg

Try out the bilsteins 24-186940 made for the NNBS. This member accidently used used them, placed the snap ring to the highest setting looking to level the truck and got an unexpecting result. After looking at the spec difference on bilstein website there is about 3-4" in extended/ collapsed length. He claims the ride is 100% better but didnt expect the height issue. Im very tempted to do this.

So if the rings are not installed the result would be a 2" drop or so?

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
