This was SUPER helpful. Just got my install on the ground! Still need to torque around. Few things are done in different orders in the paper manual so be aware. They do end up getting done just in a different order. Also on a 2021 at least you can totally get the ABS sensors with the dust cover and rotor assembly and axles on. Makes it much easier. You don't have to unclamp them etc. I did clearance the dust cover some on the ground before installing but seems to be unnecessary.
The inherent problem in lifting is that IF you put on bigger tires, you need to do a gear change as well, things go hand in hand, and without the gear change, the bigger tires you put on, the worse the vehicle drives... Having said that, I had my 2002 GMC 2500HD(Duramax) lifted with a 4.5" BDS coilover kit, up to and including brand new 5" leafsprings and dual steering stabilizers...with 35's, the gearing was set to 4.28's with a Detroit locker in the rear, and a Detroit TruTrac in the front...
@@lawman8877 I can see that you're absolutely clueless... The REASON you do a gear change, especially on a diesel is to keep the engine in prime rpm operating range...has NOTHING to do with "torque" or "horsepower"...
2 questions for ya. Any reason you don't just remove the caliper completely since you're replacing brake lines anyway? Then, is there a reason you don't just remove the spindle completely before removing the wheel bearing? Starting mine in the morning and just curious.
Cody Im think of doing this on a 06 GMC 2500hd Sierra. Big backup in Georgia where the Coil over and shocks come from right now. Do you see any problems for the 06 install?
It can, the torsion bar keys can be loaded/unloaded a bit to dial in ride height. The kit components are designed to correct steering-suspension-driveline geometry at 5-6.5" of lift.
How important is the inner seal on the knuckle? I noticed they were still my stick knuckles when cleaning up the garage. I’ve driven about 1k miles since I picked the truck after the install.
Not sure I’m comment is showing up. How important is the inner seal on the knuckle? I noticed that my stock knuckles both had the inner seal still in them. I was picking up the garage and happen to notice it. I have put about 1k miles on the truck since the lift was installed. Contacted the shop to see if they used different seals or what they would say but they definitely did not swap over the inner seals. Also, is the bracket only on the passenger side for the abs lines or is on both driver and passenger?
This is part of our R&D facility and is not open to the public. However, if you visit our website we have a section called vehicles wanted, where we recruit customer rigs for testing new model lift systems here!
Due to the design of the factory suspension/driveline geometry if you intend to use the driveshaft the rear crossmember must be cut (removed) and is replaced with a drop crossmember designed to allow sufficient driveshaft clearance. This is the case with all lift kits over 3" for these trucks. If you don't want to cut a 2-3" lift kit is your best option. He have this option available bds-suspension.com/product?kid=760FS

Nice work. This man is a suspension god.
Mate you are a good fitter and explain the job really well

You don't need a different gear with thus truck it make almost 1k torque

@wipatriot510 oh I'm not clueless at all going from a 34 inch to a 37 inch tire in the new 10 speed trucks literally drops you less then 100rpm at 60.
BDS is Hardcore heavy duty Metals 🤙🏼🤙🏼❤️ Great video
Like all the Videos and content would like a Side by Side of Before and After Each build
Damm that’s a good video. I’d let this guy work on my truck anytime
Who else watched the entire video just cuz you plan on someday owning a 2500 Sierra and installing the lift kit yourself? 😂

I did lift added 37” tires but when I hit crack or dips steering wheels shakes or kicks to one side should I add stabilizer shock or adjust gear box?
Can you do an install video for a 16-18 Silverado 4x4???

Looks like the bump stop is going to ride on or at least not much distance for drop. How does this affect ride quality.
Can the torsion bars be adjusted a bit after installation to get the desired height? PS- my truck rides amazing with the 6.5" lift and Fox resi shocks

Hey Justin,
Contact our customer service/tech support team for assistance. You can reach them at (517) 279-2135 or
Minute 33:21 of the video where can I get those torsion key brackets ? TIA
They're included in our kits, contact our sales team for more info (517) 279-2135
I really want this but I need to still be able to tow our fifth wheel RV
Man… I wish I had a two or 4 post lift.
Where is this shop located? Is it open to the public for BDS installs?

There is one thing I don’t see you guys doing. You guys do not talk about the pinion angle on the front and rear differential.
Good work
Q: does the front knuckle push out front wheel track wider than the rear?
nope, zero track width change when lifting the 11-19 HD and 20+ HD trucks.
Me still looking for my 36mm socket
buen trabajo
You guys gota be kidding me lol
First I need a bigger garage without Christmas decorations and a lift 😂 or no wife and no rugrats
you have to cut? Unacceptable.
