Ram 1500 Lift & Leveling Hub

The Ram 1500 is the platform where the first question is not “which kit?” but “which truck?” — twice over. Ram has sold two different 1500s under the same name since 2019, and offers the current one with two different front suspensions — coil springs or a factory air system that most kits exclude. Get either answer wrong and the kit simply does not fit, however good the reviews were. This hub exists to make both checks before any money moves: generations first, then the air-suspension split, then the verified data.

We have not hands-on tested kits for this platform. Everything published here is tied to a cited source — manufacturer fitment pages and listings, checked 2026-11-03 — and our method is explained in how we test and verify.

Check first: two trucks, one name

The fourth-generation Ram 1500 (the DS, 2009–2018) was replaced for 2019 by the fifth-generation DT — a different frame, different suspension, different truck. Unusually, Ram kept building the DS alongside it as the Ram 1500 Classic through the 2024 model year, so for six model years a buyer could purchase a brand-new DS or DT from the same showroom. Parts do not interchange between them, and the kit manufacturers say so in plain terms: ReadyLIFT’s DT kits state not for use on classic body style Ram 1500. The five-second field check, per RealTruck’s comparison of the two trucks: count the lug nuts. The Classic (DS) is a 5-lug truck; the DT is 6-lug. If a listing’s year range spans 2019 without naming a body style, it has not answered the first question.

Check second: the air suspension exclusion

Ram’s 4-Corner Air Suspension is the defining exclusion of this platform — on the DT it is standard on Limited and Limited Longhorn and optional across other trims, and it was available on DS trucks from 2013 as well (the DS Rebel’s air system even runs a higher normal ride height). The aftermarket’s position is consistent and blunt: Rough Country’s DT leveling kit states it does not fit models with 4-Corner Air-Suspension; ReadyLIFT’s coil-spring DT kits carry the same exclusion. A spacer designed around a steel coil has nothing to offer a system that sets ride height with air springs and a compressor.

The exclusion is not a dead end, in either generation — it is a routing instruction. For the DS, air-specific systems exist (BDS builds a 4-inch kit explicitly for 2013–2018 air-ride trucks, Rebel included). For the DT, ReadyLIFT builds a leveling kit exclusively for factory air trucks — the 66-19150 in our Ram leveling kits guide — whose exclusion list is the mirror image of the others: it will not fit coil-spring trucks. Air owners shop a smaller, separate catalogue; the mistake is shopping the main one.

2009–2018 (and the Classic): the DS generation

The DS is the truck that made coil-spring rear suspension the Ram signature, and it is now the used-market staple — including its second life as the 2019–2024 Classic. For lift buyers the DS story is simpler than the DT’s in one way (no DT-style electronics layer in the exclusion lists) and identical in another: factory air suspension, where fitted, routes you to air-specific kits, and the Rebel’s higher factory stance deserves the same measure-first respect as any factory-lift trim.

Honesty about our own coverage: our verified dataset does not yet hold a DS-scoped leveling kit or fitment row we are willing to publish. The kit records and table below are DT-only, labelled as such, rather than stretched across a generation boundary they were never verified for — the single most common fitment error on this platform. DS owners should start with the generation and air checks above and the workflow below; the catalogue work for this generation is in progress.

2019+: the DT generation

The current truck (DT, 2019–present) is where our verified data starts, and its headline pattern is convergence: three different ReadyLIFT DT kits — pre-load spacer, strut extension with control arms, and the air-suspension kit — all state the same maximum tire, a 285/65R20 (about 34.6 inches) on a 20×9 wheel with +18 offset, while Rough Country’s budget 2-inch kit states up to a 295/60R20 with a maximum width of 11.5 inches and minor trimming. Nobody verified here promises a 35×12.50 on a level, and this hub will not either. The full comparison — including which kit fits the Rebel, and why the DT’s composite factory upper control arm drives the price spread — is in best leveling kits for Ram 1500. The factory-lift notes: the Rebel carries a 1-inch factory lift (Rough Country excludes the Off-Road package and Warlock for exactly this reason), and the TRX and RHO sit outside the standard catalogue entirely — every kit we verified excludes them.

Your workflow on this platform

1. Name your generation: DS or DT — lug count settles it in five seconds.
2. Name your suspension: coil springs, or factory air? Look for ride-height controls and air springs, not just the trim badge.
3. Run both answers against the kit’s exclusion list before reading a single review.
4. Convert your tire goal with the tire size calculator, then price the whole job — kit, labour, alignment, tires — with how much does it cost to lift a truck.
