Zone Offroad D99F Lift Kit — 4" Front / 3" Rear | Fox Adventure Shocks | 2019–2024 Ram 1500 4WD | DT Platform | Daily-Driver Geometry | 33–34" Tire Clearance

Serious lift. Daily-driver geometry. Fox Adventure shocks included.

Not every Ram 1500 DT build needs maximum lift. At 4 inches of front lift, caster correction requirements are reduced compared to 6-inch configurations — less stress on CV axles and steering components, more compliant on-road geometry, and adequate clearance for 33–34-inch tires without the geometry demands of a 6-inch system. For owners who want real lift without the maximum-lift tradeoffs, the D99F is the correct call.

The Zone Offroad D99F delivers 4 inches of front lift and 3 inches of rear lift on the 2019–2024 Ram 1500 DT 4WD platform. Heavy-duty crossmembers and steering knuckles correct caster, camber, and scrub radius geometry at lifted height. Differential drop brackets correct CV axle angles. Rear coil spring replacement provides 3 inches of rear lift on the DT's coil-spring suspension. Fox Adventure Series shocks valved for the lifted geometry are included front and rear. Need clearance for 35-inch or larger tires? Step up to the D96F, D96N, D97F, or D97N.

Section 1 — Comprehensive Sizing Matrix

4-inch vs 6-inch — how to choose:

At 4 inches of front lift, the CV axle angles stay within a more comfortable operating range and caster correction demands are lower — the daily-driven Ram 1500 that commutes and occasionally trails will appreciate the reduced geometry stress over the long term. At 6 inches, you gain maximum clearance for 35-inch and larger tires but introduce higher CV angle and caster correction requirements.

The 1-inch front-to-rear differential: The kit delivers 4 inches of front lift and 3 inches of rear — a slight nose-up rake that levels out under normal bed load and towing weight.

Kit contents:

• Heavy-duty front crossmembers
• Steering knuckles
• Strut spacers
• Differential drop brackets
• Rear coil springs (3-inch lift)
• Fox Adventure Series shocks — front and rear
• All required hardware

Section 2 — Critical Compatibility

✅ This kit fits — 2019–2024 Ram 1500 DT 4WD

❌ This kit does NOT fit — read before ordering

Ram 1500 Classic owners — stop here: The Classic is the DS platform (older body style, leaf-spring rear suspension). This kit does not fit. Confirm your truck is the 2019+ DT new body style with coil-spring rear suspension before ordering.

⚠️ Air suspension note: If your Ram 1500 DT is equipped with factory 4-corner air suspension, confirm compatibility before ordering. Text (469) 407-7538 with your trim and build sheet.

Need clearance for 35-inch or larger tires: The D99F provides clearance for 33–34-inch tire packages. For 35-inch or larger, you need a 6-inch kit — see D96F (Fox, standard clearance), D96N (Nitro, standard clearance), D97F (Fox, OE 22-inch), or D97N (Nitro, OE 22-inch).

Section 3 — Before You Buy — Questions We Get Asked

Q: Why choose 4 inches instead of 6 inches?

At 4 inches of front lift, CV axle angles stay within a more comfortable operating range and caster correction requirements are lower — resulting in reduced wear on CV axles and steering components over time and more compliant on-road geometry for daily use. If the truck is primarily a daily driver or street-biased build running 33–34-inch tires that doesn't need maximum ground clearance, the D99F delivers real lift with a geometry footprint that's easier on the truck long-term. If 35-inch or larger tires are the goal, step up to the 6-inch kits.

Q: What's the difference between D99F and D96F?

Both include Fox Adventure Series shocks on the same 2019–2024 Ram 1500 DT 4WD platform. The D99F delivers 4 inches of front lift and 3 inches of rear — moderate lift, 33–34-inch tire clearance, reduced CV angle and caster demands. The D96F delivers 6 inches of front and 5 inches of rear — maximum lift, 35-inch and larger tire clearance, higher geometry correction requirements. The choice comes down to intended tire size and how aggressively the truck is built.

Q: How do I tell if my Ram 1500 is the DT or Classic platform?

Check the rear suspension. Coil springs — DT platform, this kit fits. Leaf springs — Classic DS platform, this kit does not fit. The DT launched in 2019 with a wider, more angular body. The Classic continued the older rounded body style and was sold simultaneously through 2024. Text (469) 407-7538 with your VIN and we'll confirm the platform before you order.

Q: How does this ship and what do I need to know?

At 116 lbs, this kit ships standard freight — free shipping to the Lower 48, no LTL freight coordination required. Professional installation is required. Budget for a full 4-wheel alignment at the time of install and a re-torque appointment at 500 miles.

The Obsidian Take

The D99F is for the 2019–2024 Ram 1500 DT owner who wants a meaningful lift with a geometry footprint the daily-driven truck can live with long-term. Four inches of front lift and 3 inches of rear lift keeps CV axle angles in a more comfortable operating range, reduces caster correction demands, and gives the truck clearance for 33–34-inch tire packages without the geometry stress that comes with a 6-inch system. Fox Adventure Series shocks valved for the lifted geometry handle the suspension load correctly — not generic valving on a lifted platform. Rear coil spring replacement delivers true 3-inch rear lift on the DT's coil-spring suspension. The 1-inch nose-up rake levels under bed load as intended.

This kit is not for Ram 1500 Classic DS owners — the leaf-spring rear and older body style are completely different architecture. It is not for 2025 or newer Ram 1500 owners. It is not for 2WD owners. If factory 4-corner air suspension is equipped, confirm compatibility before ordering. And if the tire goal is 35 inches or larger — the 4-inch front lift won't get you there, step up to the D96F, D96N, D97F, or D97N and build accordingly.

2019–2024 Ram 1500 4WD — DT platform only. Ram 1500 Classic (DS) does not fit. 2WD does not fit. Need 35"+ tire clearance — order D96F or D97F.
