2 Best Leveling Kits for Ram 1500

Every truck platform has one question that decides the whole purchase. On the current Ram 1500 — the DT generation, 2019 and newer — it is not trim, and it is not dampers. It is this: does your truck ride on coil springs or on factory air suspension? Ram sells the DT both ways. The 4-Corner Air Suspension is standard on Limited and Limited Longhorn and optional across much of the range — and almost every leveling kit made for this truck excludes it in the first line of its fitment notes. This guide is organised around that split. Four kits were verified on manufacturer product pages on the date shown; the two sold on Amazon — one for coil-spring trucks, one built only for air — are the picks in this guide, and the other two are covered on the hub (see “What we left out” in the buying guide below).

How we chose these kits

Verified-spec comparison, as everywhere on this site: manufacturer page, lift height, stated max tire, exclusions in the manufacturer’s words. Our method is in how we test and verify; we have not installed or hands-on tested any of these kits. Scope is the DT generation only — the DS / Ram Classic is a different truck with a different catalogue, and the Ram 1500 hub covers the split. If you read nothing else here, read the air-suspension section before the kit sections.

ReadyLIFT

ReadyLIFT 2-Inch Leveling Kit with Tubular Control Arms (66-1921)

Check Price on AmazonSource listing used for verification

Last checked November 3, 2026

Key specs

• Front lift: 2″
• Rear lift: 0″
• Type: leveling
• Max tire stated: 34.6″
• SKU: 66-1921

Why we recommend it

The 66-1921 is the top-mount strut extension version — and what it buys is the thing the DT actually needs: replacement DOM tubular steel upper control arms with corrected ball-joint angles, included because ReadyLIFT's engineers determined the factory composite arm's ball joint would be over-stressed by a strut extension alone. Two inches of lift, the same stated 285/65-20 maximum on a 20×9 +18, and an application line that names the Rebel — tempered by the same page's factory pre-lift exclusion and 22-inch hub-to-fender check, so Rebel owners should measure rather than assume.

From the Amazon listing

• 2019-2020 Ram 1500 (including Rebel) 2WD/4WD 2 inch Leveling Kit with new Tubular Upper Control Arms
• Also fits Rebel Edition
• Front strut extension leveling kit

Best for: Coil-spring DT trucks — the level done properly

Pros

• ✓ Replacement tubular UCAs with corrected ball-joint angles
• ✓ Stated 285/65-20 maximum, like the rest of the DT range
• ✓ Names the Rebel in its application line

Cons

• ✗ Excludes air-suspension trucks — that is the 66-19150's job
• ✗ Rebel fitment is measure-first: the 22-inch hub-to-fender check applies
• ✗ Excludes Classic, TRX and RHO by name

ReadyLIFT

ReadyLIFT 1.5-Inch Leveling Kit for Factory Air Suspension (66-19150)

Check Price on AmazonSource listing used for verification

Last checked November 3, 2026

Key specs

• Front lift: 1.5″
• Rear lift: 0″
• Type: leveling
• Max tire stated: 34.6″
• SKU: 66-19150

Why we recommend it

The hero of this guide, because it is the only verified answer to the platform's defining question. The 66-19150 gives a factory-air DT Ram 1.5 inches of front leveling lift using a fabricated offset steel spacer, with the same tubular upper control arms as the 66-1921, and states the same maximum tire: 285/65-20 on a 20×9 at +18. It works *with* the air system rather than deleting or fighting it — the level is modest precisely because the suspension underneath it is active. For Limited and Limited Longhorn owners, who had no choice about air suspension, this kit is the difference between 'levelled' and 'not available.'

From the Amazon listing

• 2019-2023 Ram 1500 (Factory Air Suspension) 4WD
• 1.5 inch Leveling Kit
• New Tubular Upper Control Arms included

Best for: Factory air suspension trucks — Limited and Limited Longhorn especially

Pros

• ✓ Built exclusively for air trucks — the only verified answer for them
• ✓ Tubular upper control arms included
• ✓ Same stated 285/65-20 maximum tire

Cons

• ✗ Air trucks only — will not fit coil-spring trucks at all
• ✗ 4WD only, and no EcoDiesel applications
• ✗ Measure first: over 22 inches hub-to-fender may require less lift

Buying Guide: Two Catalogues, One Truck Name

Here is the shape of the problem. A coil-spring DT Ram can be levelled with a budget spacer kit. An air-suspension DT Ram cannot use that kit, or the mid-priced one, or the premium one — Rough Country’s listing states it flatly (does NOT fit models with 4-Corner Air-Suspension), and both of ReadyLIFT’s coil-spring kits carry the same exclusion. This is not upsell theatre: a spacer engineered around a steel coil has nothing to say to a system that sets its own ride height with air springs and a compressor, and installing one anyway means fighting the truck’s own levelling logic.

The verified exception — and the reason this guide exists — is that ReadyLIFT builds a kit for the air trucks: the 66-19150, a 1.5-inch leveling kit with tubular upper control arms, designed exclusively for factory air suspension. Its exclusion list is the mirror image of every other kit here: it will not fit trucks with conventional springs and struts. So the Ram catalogue is not “kits, plus an air warning.” It is two separate catalogues that happen to share a truck name, and the first job is knowing which one you are shopping in. Check for ride-height controls on the dash, air springs at the corners, and the self-lowering Aero behaviour at speed; Limited and Limited Longhorn owners can assume air until proven otherwise, everyone else should look.

The Classic trap, once more

Everything above is DT. From 2019 to 2024 Ram sold the old DS truck beside it as the Ram 1500 Classic, and every manufacturer in this guide excludes it by name — not for use on classic body style. The two trucks share a badge and almost nothing else; the five-second tell is lug count (5 for the Classic, 6 for the DT). If yours is a Classic, you are shopping the DS catalogue, and the Ram hub is the right starting point — our verified kit data for the DS is still being built, and we would rather say that than dress DT numbers in DS clothing.

What we left out, and why

Two verified kits are not picks here, because this guide only features products sold on Amazon. Rough Country’s 35400 — the budget pre-load spacer for coil-spring trucks — and ReadyLIFT’s 66-1920 — the mid-priced pre-load kit whose own documentation honestly warns that the ride gets firmer — both stay fully documented on the Ram 1500 hub, but neither has an Amazon listing we could verify to our standard. The two picks above cover the platform’s split: one kit per catalogue.

🏆 Our Top Recommendation

ReadyLIFT 2-Inch Leveling Kit with Tubular Control Arms (66-1921)

If you want one recommendation for the majority case — a coil-spring DT Ram — it is the 66-1921: a top-mount strut extension plus the replacement DOM tubular control arms the DT's composite factory arm actually needs, with the same stated 285/65-20 ceiling as every ReadyLIFT kit here. Air-suspension trucks should skip straight to the 66-19150: it is the only pick built for them.

The 66-1921 is the top-mount strut extension version — and what it buys is the thing the DT actually needs: replacement DOM tubular steel upper control arms with corrected ball-joint angles, included because ReadyLIFT's engineers determined the factory composite arm's ball joint would be over-stressed by a strut extension alone. Two inches of lift, the same stated 285/65-20 maximum on a 20×9 +18, and an application line that names the Rebel — tempered by the same page's factory pre-lift exclusion and 22-inch hub-to-fender check, so Rebel owners should measure rather than assume.

Best for: Coil-spring DT trucks — the level done properly

Final Thoughts

Price the whole job — kit, labour, alignment — with how much does it cost to lift a truck, and if you are still deciding whether a level is even the right tool, leveling kit vs lift kit vs body lift comes before any of this.
