Lowered suspension

[formulaws6ramair]

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.

IHC 3/5 on 22’s

Tire size? Do you rub in the front? Mind if you can get a picture of how close the front tire is to the inner fender? 
 

I am back forth about 22s and I am glad I finally see a picture (albeit 3/5)

Belltech 4/6 drop on 24's. Rides great

Twisted Metalworkz ......  They have a 4 link coil over I’ve been looking at to do my 4/6 drop.  How are their products?

So far yes, but I went ahead and ordered the front struts too. The stock front end is way too bouncy. The Belltech shocks are much better than the Maxtracs.

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

That coilover kit is sweet and I'm sure it rides awesome. I'm hoping my setup will ride good and then hold me over until I can bag this truck. It'll be a good 4-5 yrs for that to happen though.

So far the quality of the notch is very nice, I'll find out on Friday how it fits. Super excited to have this truck finally ride good and not bottom out on every bump in the road. It was lowered when it had 375 miles on it, so it's basically rode like ****** for the whole time I've had it.

How many miles do you have on your truck?  I’m of the mindset of do it all at once then enjoy the ride.

1100 miles...just got it this past Thanksgiving. After I ordered the notch and it took 3 weeks to get here. It showed up just after I went back to work...after having 10 days for the holidays. I was trying to get it done over my break, just didn't work out that way.

If I had to do it all over again I might've used the Twisted Metalworkz front and rear coilover with 4 link. It's more than twice the price of the Belltech kit but it comes double adjustable vikings. I would have to assume it rides bad ass.

285/45r22.  No rubbing.  If going with 24's it's recommended to go with 295/35.  My roads are bad so I didn't want to chance it on 24's with the lower profile tires.  Sorry, I don't have pictures but I'll try get some this weekend.

IHC 3/5 on 24" dubs, planning to do a 4/6.

 

Nice!  You on Oahu?  Who did your install?  Or did you do it yourself?

Yup, on Oahu. Rads did the install and alignment.

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 lol
