The 2019+ T1XX Silverado and Sierra are extremely popular to level and lift. The new platform has a different front suspension than older generations — here’s what you need to know about leveling, tire fitment, and lift options.
T1XX Front Suspension — What Changed
The T1XX uses a multi-link independent front suspension (not the traditional double-A-arm). This design gives better ride quality but changes how leveling kits interact with the geometry.
Key difference: The T1XX does NOT have traditional strut spacers like older trucks. Instead, the front coilovers (2019+) use a different spacer design or require a specific leveling kit designed for the T1XX platform.
Leveling Kit Options
Method 1 — Upper Strut Spacers
Still the most common approach. The Maxracing 2" Front Leveling Kit for 2019+ Silverado/Sierra is a direct-fit billet spacer kit — no modifications required.
- Most popular option for 2"–2.5" leveling
- Works with factory shocks
- Alignment required after install
Method 2 — OEM UCA with Leveling
Some owners combine a leveling spacer with aftermarket upper control arms (especially for aggressive lifts 3"+). This maintains proper ball joint angles and improves geometry on bigger lifts.
What Tires Fit
| Lift | Recommended Tire | Notes |
|---|---|---|
| Stock (no lift) | 275/55R20 | Factory fitment |
| 1.5"–2" level | 285/60R20 | Clean fit, no trimming |
| 2.5" level | 295/65R20 or 305/55R20 | May need minor trimming |
| 3.5"–4" lift | 33"–35" | Requires UCA on some builds |
The T1XX has more front wheel well space than previous generations, which helps with clearance.
Lift Kits (3"+)
For lifts above 2.5", aftermarket UCAs are recommended to maintain proper ball joint angles and prevent premature wear.
Common lift kit brands for T1XX:
- Rough Country 3.5" and 5" systems
- ReadyLift 3.5" SST lift
- Cognito Motorsports (premium option for performance builds)
Trail Boss Owners
If you have a Trail Boss, it comes with a factory 2" lift from GM. A leveling kit on a Trail Boss will add to that factory lift — read your kit specs carefully. Many Trail Boss owners run a 1" spacer for a total of ~3" front lift.
Always Get an Alignment
No exceptions — align the truck every time you touch the suspension. T1XX alignment adjustments are at the lower control arm (rear eccentric bolt for camber).
