The best lift kit for a Chevy Silverado depends on which Silverado you own. A front leveling kit for a 2018 1500, a system for a new-body 2020 1500 and a kit that adds height to a factory-lifted Trail Boss are different purchases. The model year alone does not settle fitment.
These three picks cover those distinct jobs. They are based on manufacturer application notes and installation manuals, not a hands-on ride or off-road test. The shortlist is for specified Silverado 1500 applications; it does not cover 2500HD or 3500HD trucks.
Best Silverado lift kits at a glance
| Kit | Best use | Application covered here | Height and key limit |
|---|---|---|---|
| Rough Country 1307 | Modest front leveling on an older 1500 | 2007–2018 new-body Silverado 1500, 2WD/4WD; 2019 1500 LD | Advertised 2-inch front lift; no rear lift components |
| ReadyLIFT 69-39400 | A larger lift for a compatible standard-height newer 1500 | 2019–2024 new-body Silverado 1500 4WD; exclusions below | Advertised 4-inch front lift; 3-inch-tall replacement rear blocks |
| ReadyLIFT 69-3920 | Adding height to a factory-lifted Trail Boss | 2019–2024 Silverado 1500 Trail Boss 4WD; steel rear leaf springs and square U-bolts | Advertised additional 2 inches front and 1 inch rear |
Lift figures describe the manufacturer’s intended result on a compatible truck. Initial ride height, factory equipment and payload options affect the outcome. A block’s physical height is also different from the net lift obtained when it replaces an existing block.
1. Rough Country 1307: best for straightforward front leveling
Rough Country 1307 is the compact choice here: two lower strut spacers and installation hardware, intended to provide 2 inches of front lift. It is useful to consider if the goal is reducing the truck’s nose-down stance without buying a front-and-rear suspension package.
The current application list covers 2007–2018 Silverado 1500 2WD and 4WD, plus the old-body 2019 1500 LD. The 2007 Classic and the new-body 2019 1500 are outside this recommendation. Confirm the body designation before using either transition year in a vehicle selector.
Rough Country says retaining factory wheels requires its 0.25-inch wheel spacer, SKU 1065. Include that requirement in the fitment discussion with your installer. Do not read the kit’s small size as proof that every stock wheel and tire combination clears. The product page also excludes 2014–2018 Denali/Ultimate models with Magnetic Ride Control; its broader GM listing is not permission to transfer fitment across suspension systems.
- Pros: a small front-only parts package; current manufacturer fitment includes both drivetrains for the specified Silverado years.
- Limitations: no rear-height change, upper control arms or replacement dampers; factory-wheel spacer requirement.
Read the current 1307 instructions for inspection and alignment requirements. The listing below is one kit containing two lower strut extensions and hardware.

2. ReadyLIFT 69-39400: best for a compatible newer 1500 needing more height
ReadyLIFT 69-39400 is the broader parts package for a standard-height new-body Silverado 1500. The recommendation here is limited to compatible 2019–2024 4WD trucks. It excludes Trail Boss, ZR2, the old-body 2019 LD and trucks with Super Cruise. ReadyLIFT says single-cab applications have not been validated.
The system uses strut extensions, preload spacers and replacement upper control arms. It also includes rear blocks and U-bolts, rear shock and bump-stop extensions, and Adaptive Ride Control brackets. ReadyLIFT explicitly supports compatible trucks with or without Adaptive Ride Control; the installation manual has a separate ARC-bracket section.
Shop this as an advertised 4-inch front-lift kit with 3-inch-tall replacement rear blocks. Do not assume those blocks add 3 inches on top of the existing rear height. The instructions remove the factory blocks before installing replacements.
For the kit as boxed, this shortlist is restricted to traditional steel rear leaf springs and square U-bolts. The current product page identifies additional hardware for some other spring arrangements and warns about later round U-bolts. Have ReadyLIFT confirm the exact supplement for your VIN before ordering a different configuration.
- Pros: replacement control arms and rear support components included; documented ARC provision.
- Limitations: spring-compression work and strut-stud trimming appear in the instructions. ReadyLIFT does not recommend Auto 4 HI use with this kit and says it is not intended for off-road use or abuse.
Match the part number, then apply the manufacturer’s exclusions above even when a retailer headline gives a broader vehicle range.
3. ReadyLIFT 69-3920: best for the specified Trail Boss application
The ReadyLIFT 69-3920 AT4/Trail Boss Plus 2.0 is designed around the Trail Boss’s factory 2-inch front lift. Its advertised additional lift is 2 inches at the front and 1 inch at the rear. That makes it the relevant comparison for a supported Trail Boss, while 69-39400 explicitly excludes that trim.
The kit includes upper control arms, strut and preload spacers, rear blocks, U-bolts and rear jounce-stop extensions. Its 3-inch rear blocks replace the originals; the product’s additional rear-lift figure is 1 inch.
The current product heading covers 2019–2024 Trail Boss 4WD. This recommendation requires traditional steel leaf springs and square U-bolts. ReadyLIFT excludes composite mono-leaf configurations, flags later round U-bolts as incompatible with the boxed kit, and excludes ZR2 and AT4X. Do not extend it to 2025 simply because some retailer titles do.
- Pros: a system expressly designed for the factory-lifted Trail Boss application; upper control arms included.
- Limitations: spring and U-bolt checks are essential; Auto 4 HI use is not recommended. The manufacturer’s instructions prohibit combining it with aftermarket lift struts or other lift systems.
This is one complete kit listing, not a universal 2-inch spacer for any Silverado.
What to verify before buying a Silverado lift kit
Record the actual truck configuration. Give the manufacturer or installer the VIN, model year, 1500 designation, drivetrain, cab/body style, trim and suspension options. On newer trucks, inspect the rear spring construction and U-bolt shape. A factory-lifted Trail Boss and an ARC-equipped truck need explicit application support, not assumptions based on the badge alone.
Decide whether you want leveling or a larger suspension change. The 1307 raises the front only. The two ReadyLIFT systems address front and rear components and include upper control arms. If your truck already has aftermarket struts, spacers or another lift, establish the starting configuration before ordering. The ReadyLIFT manuals specifically reject stacking their systems with other lift devices.
Plan wheels and tires with the kit. Nominal tire diameter alone does not settle clearance. Width, wheel offset, actual tread shape and body openings matter; ReadyLIFT’s manuals warn that trimming can be necessary. Have the installer evaluate the complete combination through steering and suspension travel. Do not purchase on a blanket “fits 35s” promise.
Budget for the work after the parts go on. Both manufacturers call for alignment and inspection. The ReadyLIFT manuals additionally call for headlamp checks and checks of applicable camera or radar systems. Their post-installation instructions include a hardware recheck after 500 miles and periodic checks thereafter. Use the exact current kit instructions and vehicle service information for procedures and torque values.
Be realistic about the result. ReadyLIFT warns that raising the vehicle changes its center of gravity and can affect stability and control. These picks carry no promise of unchanged ride, greater towing capacity or improved off-road performance. Choose the smallest suitable change for the truck’s intended job, and confirm local vehicle-height requirements before installation.
Frequently asked questions
Will a Silverado 1500 lift kit fit a 2500HD or 3500HD?
Do not assume interchangeability. The three kits in this shortlist cover specified Silverado 1500 applications only. An HD truck needs its own verified chassis, drivetrain, suspension and model-year application.
Does a 3-inch rear block add 3 inches of rear lift?
Not when it replaces a factory block. Net lift depends on the original block and starting configuration. ReadyLIFT 69-3920 uses 3-inch replacement blocks but advertises 1 inch of additional rear lift on its supported Trail Boss application.
Can I use a standard Silverado lift kit on a Trail Boss?
Only if the kit explicitly supports the factory-lifted Trail Boss. ReadyLIFT 69-39400 excludes it. ReadyLIFT 69-3920 is the Trail Boss option here, subject to its year, drivetrain, spring and U-bolt restrictions.
Which listed kit supports Adaptive Ride Control?
ReadyLIFT 69-39400 explicitly supports compatible trucks with or without Adaptive Ride Control and includes ARC brackets. That does not establish ARC compatibility for the other kits. All other application restrictions still apply.
Will I need an alignment after installing a lift kit?
Yes. The cited instructions require alignment and post-installation inspections. Also check headlamp aim, wheel and tire clearance, brake-line and ABS-wire clearance, and applicable driver-assistance systems. Follow the exact kit manual for later hardware checks.
