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, all verified on manufacturer product pages on the date shown; three for coil-spring trucks at three prices, and one — the interesting one — built only for air.

How we chose these kits

Verified-spec comparison, as everywhere on this site: manufacturer page, lift height, stated max tire, stated price, 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.

First: the air suspension split

Here is the shape of the problem. A coil-spring DT Ram can be levelled for $54.95. 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 quick picks

Your truck	Kit	Front lift	Price basis	The catch
Coil springs, budget	Rough Country 35400	2″	$54.95 at Rough Country	Pre-load design; strut disassembly; excludes Off-Road package / Warlock
Coil springs, mid	ReadyLIFT 66-1920	2″	$209.95 at ReadyLIFT	Pre-load spacer — ReadyLIFT itself says the ride gets firmer
Coil springs, done properly	ReadyLIFT 66-1921	2″ + tubular UCAs	$559.95 at ReadyLIFT	The price of replacing the composite factory arm
Factory air suspension	ReadyLIFT 66-19150	1.5″ + tubular UCAs	$559.95 at ReadyLIFT	Air trucks only; 4WD only; no EcoDiesel

Coil-spring trucks, budget: Rough Country 35400

At $54.95, Rough Country’s 2-inch pre-load spacer kit is the cheapest verified way to level a DT Ram, full stop. It reuses your factory coil springs, states fitment for up to a 295/60R20 tire with a maximum width of 11.5 inches (its wheel and tire table shows minor trimming for that size), and carries the platform’s canonical exclusion list: no 4-Corner Air-Suspension, no Off-Road package, no Warlock (both factory-lifted an inch), no TRX.

Who should NOT buy this: air-suspension owners (see above — this is the exclusion that defines the platform), Off-Road package and Warlock owners, TRX owners, and anyone unwilling to disassemble a strut: this is a pre-load design, so the spring comes off the strut during installation, which moves it out of the casual-Saturday category for many home mechanics.

Coil-spring trucks, mid-priced: ReadyLIFT 66-1920

ReadyLIFT’s 66-1920 ($209.95) is also a pre-load spacer — 2 inches of front lift, billet aluminum, made in the USA per ReadyLIFT, max tire 285/65-20 on a 20×9 at +18 offset. What earns it the mid slot is honesty in its own documentation: ReadyLIFT states plainly that pre-load lift will deliver a firmer ride than the factory tuning, and points buyers who want factory ride quality at the 66-1921 below. When a manufacturer’s own page talks you up the range for a stated mechanical reason, that is the most useful sentence in the listing. Note the engineering context ReadyLIFT gives for the whole DT range: the truck’s composite upper control arm is why they chose a pre-load design here — they judged a plain strut extension would over-stress the ball joint.

Who should NOT buy this: the same exclusion families as the Rough Country (air suspension, Classic body, factory pre-lifted and off-road-package trucks — with a hub-to-fender check: over 22 inches may require less lift), plus anyone whose priority is ride quality, per ReadyLIFT’s own warning, and anyone without access to a spring compressor.

Coil-spring trucks, done properly: ReadyLIFT 66-1921

The 66-1921 ($559.95) is the top-mount strut extension version — and the price jump buys 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.

Who should NOT buy this: air-suspension owners (excluded — your kit is the next one), Classic owners, TRX and RHO owners (excluded by name), and budget buyers: if your truck is a mainstream coil-spring trim and the arms are healthy, the honest difference between this and the 66-1920 is longevity insurance, priced accordingly.

Air-suspension trucks: ReadyLIFT 66-19150

The hero of this guide, because it is the only verified answer to the platform’s defining question. The 66-19150 ($559.95) 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.”

Who should NOT buy this: coil-spring truck owners — the exclusion runs both ways, and this kit will not fit your truck at all. Also excluded: Classic body trucks, the TRX, EcoDiesel applications, and 2WD air trucks (this kit is 4WD only). And measure first: ReadyLIFT’s note that trucks over 22 inches hub-to-fender may require less lift applies here too.

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.

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.
