Katool 4-Post Alignment Lift - 12,000lb Capacity. Rolling Jack Included | KT-4H120X
Need a Service-Ready Alignment Lift? Step Up to the Katool KT-4H120X 12,000 lb 4-Post Lift with RJ70 Rolling Jack
Buying a 4-post alignment lift sounds straightforward until the real questions start stacking up. How stable is it under a 10,000 lb truck? Does the lifting height actually give you enough room to work underneath? And what about wheels-off service -- do you need to buy a rolling jack separately, or does the package actually come ready to work? A lot of lifts look similar in photos, but once you're using one daily, the gaps show up fast. The KT-4H120X by Katool is built to close those gaps -- a true 12,000 lb rated capacity with an RJ70 7,000 lb pneumatic rolling jack included in the box, not sold as an add-on.
The safety system is where this lift separates from the pack. Mechanical locking devices on each column with primary and secondary lock-style backups, a single-point manual safety release, a top limit switch to prevent over-travel, and a quad cable synchronization system that keeps both platforms level through every inch of travel. Max lifting height is 86.9 inches with 80 inches of underneath clearance, so you have real working room -- not just enough to squeeze under with a creeper. Lift cycle is 83 seconds up and 40 seconds down on 220V single-phase power, which is the only voltage option on this model.
What makes the KT-4H120X a genuine alignment platform is the runway setup. Rear slip plates are built into the runways, and front alignment turn plates can be added separately to complete a four-wheel alignment configuration. The included RJ70 rolling jack lets you lift the axle or frame so wheels hang free for brake jobs, tire rotations, suspension work, and more -- all without moving the vehicle off the lift. Overall length with ramps is 258 inches, overall width is 135.2 inches, and post height is 94.88 inches, so measure your bay before ordering. If you've been searching for a 12,000 lb 4 post lift that's genuinely built for daily service and alignment work out of the box, this is the one that delivers.

Benefits of the Katool KT-4H120X
Key Features of the Katool KT-4H120X 4-Post Lift You'll Love:
• 12,000 lb Drive-On Capacity: Rated for 12,000 lbs, giving you real breathing room for heavy SUVs, full-size trucks, and fleet vehicles that push lighter lifts to their limits. This isn't a lift you'll outgrow when you take on bigger jobs -- it's built to handle the vehicles most shops actually see every day.
• RJ70 7,000 lb Pneumatic Rolling Jack Included: This is the upgrade that turns a storage lift into a service platform. The RJ70 lets you lift the axle or frame so wheels hang free for brake jobs, tire rotations, suspension work, and more -- all without pulling the vehicle off the lift and onto a two-post. Most competitors sell the rolling jack separately. Here, it's in the crate.
• Alignment-Capable Runway Design: Rear slip plates are built directly into the runways, so you're already halfway to a full alignment setup out of the box. Front alignment turn plates can be purchased separately to complete a four-wheel configuration. This means you can start doing alignment work without buying an entirely separate alignment rack.
• 86.9' Max Lifting Height: Provides 80 inches of real underneath clearance when fully raised -- enough room to stand and work comfortably, not just slide under on a creeper. Whether you're doing exhaust work, transmission service, or full underbody inspections, you're not fighting for space.
• Multi-Layer Safety System: Mechanical locking devices on each column with primary and secondary lock-style backups, a single-point manual safety release, and a top limit switch. You're not relying on any single component to keep the vehicle in the air -- there's redundancy at every level.
• Free-Standing Design on 220V Power: Engineered for free-standing use without bolting to the floor. Runs on 220VAC/60Hz single-phase power, wired to a dedicated circuit with 10-gauge wire and a 30-amp breaker. No anchor bolts required for normal operation, though the concrete specs on this model are higher than smaller lifts -- 100 mm (3.93') minimum thickness in the manual's specifications but 150 mm (5.9') in its installation section, at 3,000 PSI; confirm with Katool.

*This lift is designed for free-standing use and does not require bolting to the ground for normal operation. Regardless of whether the lift is anchored, it must be installed on a concrete surface that meets the manufacturer's minimum requirements of the figures in the Katool manual (100 mm in its specifications; 150 mm in its installation section) and 3,000 PSI compressive strength. Installing this lift on inadequate concrete may result in serious injury or death. It is the customer's responsibility to verify concrete thickness and strength prior to purchase and installation.

Katool KT-4H120X Frequently Asked Questions
Will a full-size truck fit on the KT-4H120X?
Easily -- the 12,000 lb rating covers every half-ton, 3/4-ton, and 1-ton single-rear-wheel pickup with margin to spare, and the 205' runways are the longest in our Katool 4-post lineup, so crew-cab long-beds fit without overhang. For duallys, measure the outer tire-to-tire width against the 20' runways, and for commercial flatbeds and the heaviest fleet trucks the 15,000 lb Katool KT-4H150 adds capacity headroom.
Can I do wheel alignments on this lift?
Yes -- that's what the runway design is for. Rear slip plates are built into the runways, and adding front turn plates (sold separately) completes a four-wheel alignment configuration. Pair it with one of our wheel alignment machines and you have a working alignment bay without a dedicated rack.
Does the KT-4H120X run on 110V power?
No -- this model is 220V single-phase only, on a dedicated circuit with a 30-amp breaker and 10-gauge wire. If you only have 110V available, look at the Katool KT-4H110 or the Katool KT-4M110PA -- both ship standard with 110V motors.
What's included in the box?
The Katool KT-RJ70 rolling jack (7,000 lb, pneumatic) ships in the crate -- not as a paid add-on -- so wheels-off brake, tire, and suspension work is covered from day one. Rear slip plates come integrated in the runways; front turn plates are the only alignment piece sold separately.
Do I need to bolt it down, and what about my concrete?
No anchor bolts are required for normal operation -- it's engineered for free-standing use. The concrete spec is stricter than smaller lifts, though: the manual gives 100 mm (specifications) or 150 mm (installation section) at 3,000 PSI, so confirm with Katool. Verify your slab before ordering -- it's the most common install surprise at this weight class.
How does freight delivery work?
The lift ships as freight at a net weight of 3,373 lbs plus the rolling jack. You can choose curbside freight delivery or free pickup at one of 19 warehouse locations nationwide -- enter your ZIP above to find the closest one. Most orders arrive within 1-2 weeks.
Is the Katool KT-4H120X worth it?
Price it against buying the pieces separately: a comparable 12K 4-post plus a 7,000 lb rolling jack typically runs well past this package. See the Reviews tab above for buyer feedback, and for a deeper look at the brand read our Are Katool Car Lifts Worth It? breakdown on Garage Equip Pro Guides.

Recommended Concrete Slab & Electrical Setup
Verify your shop bay dimensions before installation. Contact our lift specialists at contact@garageequippro.shop with any questions.
Concrete Slab Depth
9K–11K lb lifts typically require 4″–5.9″ of 3,000 PSI cured concrete (28+ days cure on new pours). Heavy-duty 12K–16K lb models require 5″–6″ depth.
Electrical Supply
Most 2-post lifts and commercial 4-post lifts use a dedicated 220V single-phase 30A circuit breaker. Select 8,500 lb & 9,500 lb 4-post storage lifts offer 110V options.
