Best Lift Kits for Ford F-150 (3″ and Up: SST to Full Suspension)

Above a leveling kit, the questions change. A 2-inch spacer is a stance decision; a 3.5-inch mid-lift or a 6-inch system is a geometry decision — control-arm angles, driveshafts, steering knuckles, and on some kits a cutting torch. This guide covers the F-150 at 3 inches and up: the SST mid-lifts that keep the factory architecture, and the full suspension systems that replace it. If you are still deciding between a level and a lift, start with best leveling kits for 2021+ Ford F-150 and leveling kit vs lift kit vs body lift; if you already know you want height, read on.

Every kit here was verified on its manufacturer’s product page on the date shown, with one labelled exception. Our method is verified-spec comparison: no hands-on testing, no scores, no overall winner — the right kit depends on the tire you are targeting and the trim you own.

2021 and up: the current truck

Best value mid-lift: ReadyLIFT 3.5″ SST (69-21350)

The 69-21350 is the kit this site previously carried as an unscoped SST entry — we have now verified the current manufacturer page and scoped the record properly: 2021–2026 F-150 4WD, 3.5 inches of front lift (ReadyLIFT notes the amount may land between 3.25 and 3.5) and about 1.25 inches at the rear from a 2.5-inch block. At $949.95 it is the cheapest way here into a kit that includes DOM tubular upper control arms — the part that keeps a 3.5-inch level honest at full droop. Its tire statement is the most precise in this guide: 35x11.50 or 295/60-20 on a 20×9 wheel at +18 offset, with 35x12.50 possible at 0 offset with some trimming. And it is the only kit in this guide whose manufacturer states it works with CCD and auto-leveling headlamps. A 2WD sibling (69-21352) exists at the same price.

Who should NOT buy this: owners of factory pre-lifted or off-road-package trucks — ReadyLIFT bars the kit where hub-to-fender height exceeds about 22 inches, which captures the Tremor and FX4 — and standard-cab owners, on whom it is untested.

The premium mid-lift: ReadyLIFT SST2.1 with Falcon shocks (62-21440)

Same 3.5-inch stance, different philosophy: instead of spacing the factory struts, the SST2.1 replaces them with Falcon 2.1 monotube struts and adds adjustable Falcon rear shocks, tubular UCAs and a carrier-bearing drop, for $3,149.95. ReadyLIFT’s no-trim tire statement matches the spacer kit’s (295/60R20 on a 20×9 at +18; 35x12.50 at 0 offset with minor trimming). This is the mid-lift for owners who were going to replace tired dampers anyway — the lift and the damping upgrade are the same purchase.

Who should NOT buy this: 2WD owners (not designed for the truck), and anyone whose factory struts are fresh and healthy — for stance alone, the 69-21350 does the same geometry for a third of the money.

The budget 3 inches: Rough Country 3″ Lift Kit (41430 family)

A correction worth printing: despite what roundup sites repeat, Rough Country’s current 2021+ F-150 kit is a 3-inch kit, not a 3.5. From $699.95 in its base spacer configuration (loaded-strut and premium-shock configurations cost more), with forged upper control arms and an honest tire ceiling — Rough Country states up to 34-inch tires, and its install documentation names 295/70R18 / 295/60R20 on 9-inch wheels at +12 offset as the development fitment. A manufacturer that prints a 34-inch ceiling on a 3-inch kit is telling you the truth about trimming; plan your tire around it.

Who should NOT buy this: CCD owners and Tremor owners (excluded outright), standard-cab owners (excluded), and owners whose stock hub-to-fender height already exceeds 22 inches — Rough Country says the base spacer configuration will not work, and names FX4 and Snow Prep packages as likely over the line. The 3.0L Power Stroke diesel also excludes the replacement-strut configurations.

Best full system for 35s: BDS 4″ (BDS1583 family)

At 4 inches you leave spacer architecture behind: BDS’s system works with replacement knuckles and crossmember drops, configured from $1,966.60 with NX2 shocks (FOX 2.0 at $2,266.60; a FOX 2.5 Performance Elite coil-over version reaches $4,408.60), and BDS states clearance for up to 35-inch tires. One transparency note, in the pattern we used for Bilstein in our leveling guide: BDS’s own page verifies the kit, its prices and its tire headline, but the numbered fitment notes in our kit record (18-inch-minimum wheels, the two-piece-driveshaft shim kit, the diesel and Tremor exclusions, “not tested with BlueCruise”) come from dealer listings reproducing BDS’s fitment data, because BDS’s fetched page text did not include its notes table. They are labelled that way in the record.

Who should NOT buy this: diesel and Tremor owners, and CCD owners — your truck is a separate BDS variant (BDS1961H at 6 inches), not this one.

Best for 37s: BDS 6″ (BDS1579 family)

This is the only kit in the guide whose manufacturer states a 37-inch fitment: BDS says the system provides “clearance for up to 37″ tires,” with 37x12.50 on a 20×9 in its fitment data. Configured from $2,018.60 (NX2, 4-inch rear block) to $2,387.60 (FOX 2.0, 5-inch block). The same dealer-reproduced fitment notes apply, plus two of its own: the 2-piece-driveshaft shim kit is not included, and front crash bars may require modification.

Who should NOT buy this: the same diesel/Tremor/CCD exclusions as the 4-inch apply, and add anyone unwilling to give up stock wheels — 18-inch or larger aftermarket wheels are required, and stock 17s and 18s cannot go back on.

The cheapest 6 inches: Rough Country 6″ (587 family)

From $1,399.95 — hundreds under BDS — and the compromises are printed on Rough Country’s own page, which is to its credit: the install requires cutting and drilling, wheels must be 20 inches or larger to clear the supplied knuckle, and the wheel-and-tire table tops out at 35x12.50. Read that last point twice. The general fitment ladder (our fit-35s guide works through it) associates 6 inches with 37s, but this kit’s manufacturer claims 35s. If 37s are the goal, the BDS above is the verified route; if 35s at 6 inches of stance are the goal, this is the value pick.

Who should NOT buy this: single-cab and two-piece-driveshaft trucks (excluded), CCD and Tremor trucks (excluded), and anyone who wants the install to be reversible.

2015–2020: the older truck’s mid-lift

ReadyLIFT 3.5″ SST (69-2300)

The previous generation’s SST carries a transparency note we will not hide: ReadyLIFT’s live site no longer serves a fetchable product page for the 69-2300, so this record is built from multiple dealer listings reproducing ReadyLIFT’s own copy verbatim — the same standard we applied to Bilstein’s application data in the leveling guide. On that basis: 3.5 inches of front lift, upper control arms, pre-load and top-mount spacers in the box, $949.95 across dealer listings, and a stated fitment for up to 35-inch tires (35x11.50 recommended; 35x12.50 max on a 9-inch wheel at +12 offset). ReadyLIFT’s year coverage is shown as 2015–2020 in the product name and 2014–2020 in its own kit index — check your exact year against a listing before ordering.

One honest confusion in the sources, explained rather than smoothed over: the rear lift is described as 2 inches in ReadyLIFT’s prose, the supplied rear blocks are 3 inches tall, and one dealer’s spec table says 1.75. Those numbers reconcile — the 3-inch block replaces a factory block, so the net lift is what’s left after the swap — but which net figure is exact, 1.75 or 2, the sources do not agree on. We record 2 (the manufacturer’s prose) and say so.

Who should NOT buy this: owners of factory pre-lifted or off-road-package trucks (the same hub-to-fender caution applies), and anyone uncomfortable buying a kit whose manufacturer page we could not fetch — the record says exactly what it is built from.

What changes at 4 inches and up

Three practical lines separate the SSTs from the full systems in this guide. Reversibility: spacer-and-block kits unbolt; the Rough Country 6-inch kit’s cutting requirement does not un-happen. Wheels: both full-system brands impose minimum wheel diameters (18-inch for BDS, 20-inch for Rough Country’s knuckle), which can add a wheel set to a budget that assumed the stock wheels stay — our F-150 lift kit cost guide prices that honestly. Driveshafts: two-piece-driveshaft trucks need carrier-bearing attention on both brands (included with the SST2.1, a separate shim kit at BDS, an outright exclusion on the Rough Country 6-inch).

Sources for this guide (checked 2026-11-03): ReadyLIFT’s 69-21350 product page; ReadyLIFT’s 62-21440 SST2.1 page; Rough Country’s 3-inch kit page and 6-inch kit page; BDS’s 4-inch and 6-inch product pages, with fitment notes as reproduced in BDS dealer listings; ReadyLIFT 69-2300 data as reproduced in dealer listings (XDP, TruckSpring, Speedway Motors).
