Rough Country is the most-searched lift kit brand for Wranglers, and for good reason — it's the budget entry point most owners consider first. But "Rough Country lift kit" isn't one product. Depending on your generation, door count, and engine, you're buying a different kit with different parts inside the box. Here's what each one actually includes, straight from the manufacturer and retailer spec sheets — no guessing.

JK & JK Unlimited (2007–2018)
The JK is where Rough Country offers the most SKU variety, and the specs actually differ by door count:
- Series II 2.5" Lift Kit (635) — the base kit for JK/JKU. Includes front and rear coil spring spacers, brake line brackets, a rear track bar bracket, and sway bar links. You choose shock relocation brackets (reuse your factory shocks) or add Rough Country's own shocks. Rated for up to 35" tires.
- 2.5" Lift Kit for JK Unlimited (67930) — instead of spacers, this one includes actual lifted coil springs plus N3 shocks, factory-tuned to keep ride quality close to stock.
- 2.5" Lift Kit for JK 2-Door (PERF678) — same spring-and-shock format as the Unlimited kit, but the 2-door version is rated to 33" tires rather than 35".
- 3.25" Lift Kit for JK 4-Door (PERF694) — a step up in height for owners planning larger tires from the start, also built around new coil springs and shocks rather than spacers.
JL & Gladiator (2018–present)
The 2.5" Lift Kit for JL (67700) is a spacer-based kit: it keeps your factory coil springs in place and adds coil spacers, sway bar endlinks, bump stops, and either shock extensions or a shock upgrade. It's rated for up to 35" tires and fits both 2-door and 4-door JL models.
One fitment detail worth knowing before you buy: this kit does not fit the Rubicon 392 or Mojave Edition — those trims have different factory suspension tuning that the standard spacer kit isn't designed around.
Because the JL's factory suspension already handles bump steer differently than older Jeeps, Rough Country also sells a matching N3 Dual Steering Stabilizer for JL & Gladiator (2.5"–8" lift). Steering stabilizers don't replace a track bar or tie rod — they dampen the vibration and bump steer that gets more noticeable once you're running larger tires on a lift. Worth adding to the cart if you're also going up in tire size.
TJ (1997–2006)
Unlike the JK/JL, the TJ kit is not a spacer kit — it's a full spring replacement, because the TJ's coil-sprung suspension needs new springs tuned to the vehicle's weight to lift correctly and stay level.
- 2.5" Lift Kit for TJ 6-Cylinder (653.20) — includes progressive-rate front and rear coil springs (roughly 115 lb/in initially, progressing to 160 lb/in under compression) plus four N3 shocks. This kit is built specifically for the 4.0L six-cylinder and does not fit 4-cylinder TJs.
- 2.5" Lift Kit for TJ 4-Cylinder (652.20) — the equivalent kit tuned for the lighter 4-cylinder engine.
Both are rated for up to roughly 31" tires with proper wheel backspacing, and both level out the factory rake (TJs sit slightly nose-down from the factory; the kit corrects that along with adding height).
YJ (1987–1995)
The YJ is the oldest platform still getting a dedicated Rough Country kit, and it's built around leaf springs front and rear rather than coils. The 2.5" Suspension Lift Kit for YJ (615.20) includes new front and rear leaf springs (double-tapered with Teflon pad inserts to reduce spring friction), U-bolts, bushings, and shocks. It's rated for up to 31" tires with the right backspacing.
Because it's a leaf-spring swap rather than a spacer or coil-spring job, YJ owners doing this install should plan on more time under the Jeep — the leaf spring hardware requires supporting the axle on a jack and working the spring pack loose from both the frame mount and the shackle, then torquing everything (typically around 65 ft-lbs on the U-bolts) only after the vehicle's weight is back on the suspension. Installing before the Jeep is on the ground can pin the springs in the wrong position.
What the Kit Doesn't Include
None of these kits are a complete, drive-away solution by themselves. Budget for:
- An alignment after any lift — non-negotiable, on every generation.
- A steering stabilizer if you're also upsizing tires, especially on JK/JL — see the JL section above.
- The exhaust spacer kit on 2012+ JK models (noted above).
- Extended brake lines if you go beyond what the included brackets can handle — none of these 2.5" kits require them by default, but if you later stack a body lift on top, that changes.
The Honest Trade-off
Rough Country's kits are the most accessible price point in every generation here, and the specs above show real engineering behind them — this isn't a "cheap spacer and nothing else" product line. But as covered in our brand comparison guide, owners in the Jeep community have reported spring sag over time and some highway steering wander on the budget tier compared to mid-tier brands like Rancho or TeraFlex. For light trail use and a better stance, that trade-off is usually fine. If you're planning to run 35s hard and keep the Jeep for years, it's worth reading that comparison before you commit.
Before ordering any of these, confirm your exact year, trim, and door count against Rough Country's fitment page — the JK alone has four different kits depending on those variables, and an easy mix-up is ordering the 2-door kit for a 4-door Jeep (or vice versa).
