Zone Off Road 6" Lift Kit — Ram 1500 4WD (Large Bore Knuckle, Strut Spacer / FOX 2.0 Adventure Series Rear Shocks) SKU: ZOND97F

Overview

This is Zone Off Road's 6" lift kit for the Ram 1500, 4WD, configured with the large-bore OE-type steering knuckle — required for Rams with factory 22" wheels — and upgraded FOX 2.0 Adventure Series rear shocks. The system uses top-mount strut and pre-load spacers up front and 5" rear coil springs, with high-strength CNC-machined steering knuckles and a heavy-duty differential skid plate, for clearance up to 37" tires.

Before ordering: This kit will not fit the 2019–2021 Ram 1500 Classic (see the 2018 kit listings instead), diesel models, models with the Thermal Axle option (build code DSK-P, or check the diff cover for cooling lines), or models with factory rear airbag suspension. This is the Large Bore knuckle configuration, required for Rams with factory 22" wheels (build code WPM or WPZ) due to their larger wheel bearing assembly. If your Ram does not have factory 22" wheels, the Standard knuckle configuration is the correct kit instead — not this SKU. If your truck has the Off-Road Group option (similar to Rebel), special installation steps apply — confirm with your Ram dealer using your VIN whether "Off-Road Group" appears under Optional Equipment on your window sticker. Fitment coverage varies significantly by model year, trim, and fuel type (gas vs. mild hybrid) — confirm your exact configuration against the Verified Fitment table before ordering.

Required separately: None specified beyond the kit contents — confirm wheel/tire selection against the backspacing guidance below.

Verified Fitment

Ram 1500, 4WD unless noted (ALL = all drivetrains offered)

*Rebel: Listed with Position "N/A" in the source fitment data across all years, distinct from other trims. Rebel is also called out separately in Critical Compatibility as requiring the same special installation steps as the Off-Road Group option.

Does not include the 2019–2021 Ram 1500 Classic — see Critical Compatibility. This fitment table reflects the general Ram 1500 lineup; whether a given truck requires this Large Bore knuckle configuration specifically depends on its wheel size (factory 22") rather than model year or trim.

Component Specifications

What Is and Is NOT Included

Included:

• High-strength crossmembers
• Large-bore steering knuckles, CNC machined
• Strut spacers (top-mount strut and pre-load spacers)
• Differential relocation brackets
• Heavy-duty differential skid plate
• 5" rear coil springs
• FOX 2.0 Adventure Series rear shocks

Not included:

• Standard-bore knuckles (this kit is specifically for factory 22"-wheel trucks; if your truck does not have factory 22" wheels, the Standard knuckle configuration is the correct kit instead)
• Wheels and tires

Critical Compatibility

• Does not fit 2019–2021 Ram 1500 Classic. Refer to Zone's 2018 kit listings for that model instead.
• Does not fit Diesel models.
• Does not fit models with the Thermal Axle option. Reference build code DSK-P, or check the differential cover for cooling lines.
• Does not fit models with factory rear airbag suspension.
• Knuckle bore size: This is the Large Bore knuckle configuration, required for Rams with factory 22" wheels due to their larger wheel bearing assembly — reference build code WPM or WPZ. If your truck does not have factory 22" wheels, use the Standard knuckle configuration instead, not this SKU.
• Off-Road Group / Rebel: Vehicles equipped with the Off-Road Group option require special installation steps similar to the Rebel trim. Confirm with your Ram dealer, using your VIN, whether "Off-Road Group" appears under Optional Equipment on your window sticker.
• Ride height on Rebel / Off-Road Group trucks: With the 6" kit and preload spacer installed, these trucks sit roughly 1/2" front-high. Without the preload spacer installed, they sit about 3/8" nose-low.
• Wheels: Stock 20" wheels can be reinstalled with factory tire size. If using 18" wheels at maximum recommended backspacing, test-fit wheels on the vehicle before mounting tires to ensure clearance.
• Recommended tire/wheel combinations: 37x12.5 tires with 20x9 wheels and 5" backspace, or 37x12.5 tires with 18x9 wheels and 5.5" backspace. Trimming may be required for either combination.
• Shock seal wear is not a warranty defect: Consistent with Zone's warranty terms, shock oil seal wear over time is expected and not covered on FOX Adventure Series shocks, except for leaking seals under 2 years from purchase that are free of contamination or misuse.
• Not for competition or commercial use under full warranty terms: Competition/racing use voids the warranty entirely; commercial-application vehicles carry only a 1-year warranty term rather than the full coverage described above.

Installation Notes

Estimated install time is 8 hours; Zone rates this installation as Moderate difficulty. Zone strongly recommends installation by a certified mechanic; if self-installing, read, understand, and follow all instructions and warnings before beginning. Confirm your truck's knuckle bore requirement (this Large Bore kit is for 22" wheel trucks specifically) and whether the Off-Road Group option applies before beginning installation, since both affect installation steps and final ride height. Refer to the current Zone Off Road installation instructions supplied with this kit for complete procedures, torque specifications, and all safety requirements.

The Obsidian Take

The ZOND97F is Zone Off Road's 6" Ram 1500 lift kit in its Large Bore-knuckle, strut-spacer front / FOX 2.0 Adventure Series rear configuration, using 5" rear coil springs rather than a block kit. This is the correct configuration specifically for Rams equipped with factory 22" wheels, whose larger wheel bearing assembly requires the large-bore knuckle — if your truck doesn't have factory 22" wheels, the Standard knuckle kit is the right choice instead. It clears up to 37" tires with the right wheel and backspacing, and the FOX 2.0 Adventure Series shocks step up from the base Nitro Series with an IFP monotube design and race-developed valving. Confirm these application conditions before ordering: it doesn't fit the 2019–2021 Classic body style, diesel models, Thermal Axle-equipped trucks, or factory air-suspension trucks. Off-Road Group and Rebel trucks have their own installation considerations and resulting ride height. Zone backs the kit with a 3-year/36,000-mile warranty on hard parts, converting to a limited lifetime warranty for as long as the original purchaser owns the vehicle — with the usual shock-seal-wear and off-label-use exclusions.

This Product Is For You If

• You own a 2019–2024 Ram 1500 (non-Classic), 4WD, whose exact model year, trim, and fuel type appears in the Verified Fitment table.
• Your truck has factory 22" wheels (build code WPM or WPZ), requiring the large-bore knuckle.
• You want upgraded FOX 2.0 Adventure Series rear shocks over the base Nitro Series option.
• You are not running the Thermal Axle option or factory rear airbag suspension.
• You are running up to 37" tires with appropriate wheel backspacing.
• You are prepared for a moderate-difficulty, 8-hour professional installation.

• Your truck has the Off-Road Group option or is a Rebel and you have not reviewed the specific installation and ride-height notes that apply.
• You intend to use the vehicle for competition or racing.

Common Questions

Does this fit the Ram 1500 Classic?
No. It does not fit the 2019–2021 Ram 1500 Classic — refer to Zone's 2018 kit listings for that model.

Does this fit diesel Ram 1500s?
No.

How do I know if I need the Large Bore knuckle?
Rams with factory 22" wheels require the large-bore knuckle due to a larger wheel bearing assembly — reference build code WPM or WPZ. If your truck doesn't have factory 22" wheels, use the Standard knuckle kit instead.

How do I know if my truck has the Off-Road Group option?
Call your local Ram dealer, provide your VIN, and ask them to pull your window sticker. Look under "Optional Equipment" for a line item reading "Off-Road Group."

What happens to ride height on a Rebel or Off-Road Group truck?
With the preload spacer installed, the truck sits roughly 1/2" front-high. Without the preload spacer, it sits about 3/8" nose-low.

Does this fit factory air suspension trucks?
No.

What tire size does this kit support?
Up to 37" with 20x9 wheels and 5" backspace, or 37x12.5 with 18x9 wheels and 5.5" backspace. Trimming may be required. If using 18" wheels at max backspacing, test-fit before mounting tires.

Can I reinstall my stock wheels?
Stock 20" wheels can be reinstalled with the factory tire size.

What's different about the FOX 2.0 Adventure Series shocks compared to the Nitro Series?
The FOX 2.0 Adventure Series uses a 2" diameter steel body with an internal floating piston (IFP) monotube design, a 5/8" hard chrome plated shaft, race-developed high-flow piston, and application-specific valving, finished in clear anodizing.

What is the warranty?
Zone provides a 3-year/36,000-mile Worry Free warranty on hard parts and wearable items like ball joints, tie rod ends, and bushings — shocks are excluded from this initial period. After that, a Limited Lifetime Warranty covers defects in material and workmanship for as long as the original purchaser owns the vehicle. See full warranty summary below.

Are the included FOX shocks covered under warranty?
Shock oil seal wear over time is expected and not covered on FOX Adventure Series shocks. Leaking seals under 2 years from purchase, free of contamination, damage, or misuse, can be considered for warranty.

Does the warranty cover racing or commercial use?
No — competition or racing use voids the warranty. Commercial-application vehicles are covered for only 1 year rather than the full warranty term.
