Generation & Trim Notes
This page covers the GMC Sierra 3500HD from the 2017 model year on. That spans two generations: 2017-2019 trucks (the body style sold from 2015) and the redesigned trucks sold from 2020, which were refreshed for 2024. Many suspension parts differ between 2017-2019 and 2020+ trucks, so check the years on each part.
HD trucks use torsion-bar front suspension, so front leveling is done with adjustable torsion keys rather than strut spacers. Drivetrain (4x2 vs 4x4), cab, bed length and engine also change what fits. The 3500HD is sold with single or dual rear wheels (DRW, dually); wheel spacers and many rear lift kits do not fit dually trucks.
Check Before You Buy
- Wheels and wheel spacers use an 8x180 bolt pattern.
- Torsion keys for 2017-2019 trucks and 2020+ trucks are different parts.
- Turning the torsion bars up firms up the ride. Above about 2 inches, upper control arms are common to keep ball-joint angles in range.
- Dually (DRW) trucks use different wheels; most wheel spacers do not fit them.
- Get an alignment after changing torsion key settings.

FAQ
Will parts made for another generation fit my GMC Sierra 3500HD?
Often not. Generations usually have different frames, mounts and wiring, so many parts are specific to one. Always check the fitment line on each product.
Do trims change what fits?
Sometimes. Off-road and performance trims, hybrids and special editions can differ in suspension, axles, wheel specs or underbody layout. Where a manufacturer lists trim exceptions, we show them.
Does Octarak sell parts?
No. We link to retailers, and you buy from them directly.
How is fitment checked?
We use manufacturers' published fitment and show the source and the date we checked it. Fitment can still be wrong or change, so confirm with the retailer before buying. You can also report an error.
