The best leveling kit for a Silverado 1500 starts with its suspension and exact model year. A torsion-key kit for an older 4WD truck does a different job from a strut-spacer kit for a newer truck. This shortlist compares three documented Rough Country options: 28330 for eligible older torsion-bar trucks, 1307 for eligible later strut-front trucks and 1323 for eligible new-generation models.
These are specification-based buying choices, not a road-test ranking. We have not installed the kits, measured lift height or tested ride, braking or tire clearance. Have the manufacturer and a qualified installer check the VIN, suspension options and current kit instructions before ordering.
Choose by truck generation and suspension
| Exact kit | Silverado application to verify | Package approach | Key limit |
|---|---|---|---|
| Rough Country 28330 with N3 shocks | 1999–2006 1500 4WD; 2007 1500 Classic 4WD | Nominal 1.5–2-in kit; torsion keys, rear blocks and four shocks | Excludes 1999 old body style; not a general 2WD kit |
| Rough Country 1307 | 2007–2018 strut-front 1500, RWD/4WD; 2019 1500 LD | Nominal 2-in front lift; two lower-strut spacers and hardware | Check suspension options and the current factory-wheel spacer note |
| Rough Country 1323 spacer configuration | 2019–2026 1500, RWD/4WD, including 2026 LTD where listed | Nominal 2-in front lift; two upper-strut spacers and hardware | Excludes Trail Boss, ZR2, Super Cruise and LD models |
A 2007 Silverado 1500 Classic and a 2007 newer-body Silverado are not interchangeable applications. The same distinction matters between a 2019 Silverado 1500 LD and a new-generation 2019 1500. Check the complete model designation, drive type and suspension layout, not just “Silverado 1500” in a retailer title.
1. Rough Country 28330: for eligible older 4WD trucks
The 28330 configuration is the N3-shock version for the older torsion-bar application. It includes front adjuster keys, rear lift blocks, U-bolts and hardware with four N3 shocks. That is a fuller suspension package than a pair of front strut spacers, so compare the complete scope of work and the condition of your existing shocks.
Rough Country lists 1999–2006 Silverado 1500 4WD and 2007 Silverado 1500 Classic 4WD; it separately lists 2003–2005 AWD applications. The 1999 old body style is excluded. Do not extend this fit to coil-spring 2WD trucks, 1500HD/2500HD models or a different generation.
The selected SKU title and N3 manual identify a 1.5–2-in kit, while some family-page and retailer wording says 1.5–2.5 in. Use the selected kit’s current instructions and obtain confirmation of the permitted setting; do not use that inconsistent wording as permission to raise the truck farther. The rear blocks replace the factory blocks, so a block’s physical height is not necessarily the net rear lift.
Stored torsion-bar energy makes correct tooling and professional handling important. The manual calls for a torsion-bar removal tool and warns about that stored energy. It also identifies possible clearance work at the rear shock/e-brake bracket, plus alignment and headlight checks. A generic “no special tools” promise is not appropriate for this package.

2. Rough Country 1307: a lower-strut spacer option
The 1307 kit supplies two lower-strut spacers and hardware for a nominal 2-in front lift. The manufacturer’s procedure does not require taking apart the strut assembly, but it still involves suspension and steering work followed by an alignment. It does not include replacement shocks or rear lift blocks.
Its current application table lists 2007–2018 Silverado 1500 RWD/4WD and the 2019 Silverado 1500 LD. Rough Country says it works with factory control arms, but excludes the related 2014–2018 Denali/Denali Ultimate magnetic-ride application. Confirm any electronic-suspension option on your own truck instead of assuming every trim is covered.
The current product page calls for a 0.25-in wheel spacer, SKU 1065, to retain factory wheels. The linked instructions describe development with factory wheels and do not state that same requirement. Have Rough Country and the installer resolve the wheel/kit combination before purchase. Neither source establishes that every factory wheel or larger tire will clear without further checks.
3. Rough Country 1323: for eligible newer-generation trucks
Select the 1323 upper-strut spacer configuration specifically. The same family page also offers N3 loaded struts, which are a different package. The spacer version lists two upper spacers and hardware; the current page and retailer contents also list bolt-retention plates. Confirm the current packing list, since product photos and older instructions may show an earlier hardware arrangement.
The current page covers eligible 2019–2026 Silverado 1500 RWD/4WD models and lists the 2026 LTD. It excludes LT Trail Boss, Custom Trail Boss, ZR2, Super Cruise-equipped trucks and LD models. Shared GMC exclusions include adaptive-ride Denali/Denali Ultimate, AT4 and AT4X. A separate diesel warning on that configurable page applies to the N3 strut option; it is not a blanket engine-fit statement for the spacer SKU. Confirm your exact engine and suspension combination.
The linked 921132300B instructions are labeled for 2019–2020, while the current product table covers later years. Those instructions call for a spring compressor to rotate the strut and for trimming the upper studs. Have the installer obtain the applicable instructions for the truck and current kit revision. Do not transfer the 1307 kit’s strut-disassembly statement to this upper-spacer design.
What to check before buying
- Give the installer the VIN, complete model designation, 2WD/4WD/AWD status, suspension option codes, engine, wheel dimensions and any existing modifications. A six-lug wheel pattern or a matching model name alone does not establish fit.
- Measure the truck’s current stance and explain how you normally load or tow with it. A front-leveling kit is a ride-height change; this comparison does not establish increased payload, towing capacity or a cure for load-related rear sag.
- Have the exact tires and wheels checked through steering and suspension movement. Rough Country expressly calls for test fitting; some wheel/tire combinations require trimming. A nominal two-inch lift is not a universal tire-size guarantee.
- Budget for installation, alignment, headlight adjustment and the required follow-up inspections, plus any confirmed wheel or suspension parts. Compare the complete installed package rather than the spacer price alone.
Rough Country recommends a certified technician for these kits. Its manuals warn that a taller vehicle has greater rollover susceptibility and that larger or heavier tires can reduce braking performance. They also caution against adding parts to exceed the intended height. Keep the vehicle and kit instructions with the service records and follow the specified torque and inspection schedule; no kit here is promised to preserve handling or make installation risk-free.
Frequently asked questions
Is the 28330 kit the same as a front-only leveling spacer?
No. The selected 28330 N3 package includes rear blocks and replacement shocks as well as front torsion keys. The 1307 and 1323 spacer packages have different contents and applications.
Does a two-inch kit have to be two inches thick?
Do not choose a kit by measuring the loose spacer alone. The advertised lift describes the intended vehicle ride-height change. Buy by exact part number, fitment and the manufacturer’s installation limits, and have the finished height and alignment checked.
Can I stack another spacer on an existing lift?
Do not assume that is permitted. Rough Country’s instructions caution against altering or combining parts to exceed the purchased kit’s intended height. Have existing modifications reviewed before selecting another suspension component.
