A 2-post car lift is the single best investment you can make in your shop or home garage. It gives you full access to the undercarriage, exhaust, suspension, and drivetrain — and turns a back-breaking job into a comfortable, professional one. Every serious repair shop has one.

Installing a 2-post lift requires attention to detail and for most shops we recommend professional installation. But if you're a hands-on technician who wants to do it yourself, this guide walks you through every step — from verifying your concrete to testing the lift arms before your first vehicle goes up.

Before You Begin: Evaluate Your Space and Concrete

Concrete requirements

The most critical pre-installation check is your concrete floor. A 2-post lift puts enormous point-load stress on two anchor locations. Most manufacturers require:

If your floor doesn't meet specs, dig down where each column will sit (typically 2 ft × 2 ft × 1 ft), pour new concrete, cure for 28 days, then proceed. Never anchor into weak or shallow concrete.

Bay dimensions and positioning

Most 2-post lifts need to be positioned roughly 13 feet from the bay door to allow enough room to drive a car in and raise it fully without the rear overhanging. Confirm this against your model's manual.

Receiving the lift

A 2-post lift ships on a freight truck and typically weighs 1,200–1,800 lbs. Arrange a forklift for delivery day ($100–$200/day rental). Ask the carrier to call you 24 hours ahead so the forklift is ready. When removing packaging, be careful around the hydraulic power unit — it sits on top of the folded lift and can be damaged if dropped.

Tools and Materials You'll Need

Gather all of these before starting. Stopping mid-installation to find a tool is how mistakes happen.

• Two 10–12 ft step ladders
• ISO 32 Light Hydraulic Oil (~12 quarts)
• Tape measure
• Chalk line
• Rotary hammer drill + ¾ in. bit
• 4-foot level
• Socket & open wrench set (½ – 1½ in.)
• Torque wrench
• Vise grips
• 8mm socket head wrench
• Horseshoe shims
• Teflon tape
• Dust mask and ear protection
• Safety glasses

Symmetrical vs. Asymmetrical: Know Your Lift Before You Install

Symmetrical lifts center the vehicle between both posts. Arms are equal length front and rear. Most common configuration for passenger cars and light vehicles.

Asymmetrical lifts (like the BendPak XPR-10A or Challenger CL-10 Versymmetric) rotate the columns slightly inward so rear arms are longer. The vehicle sits further back, letting the door open fully — ideal for trucks and SUVs.

Column orientation for each type is specific to your model. If you're unsure, call us at 800-562-4791 before you start marking the floor.

Step 1 — Pre-Thread Cables and Position the Columns

Thread the cables first

Before standing the columns up, thread the safety cables and equalizer chains inside them while they're still flat on the floor. Far easier than doing it after they're vertical.

Snap a chalk line

Measure the correct center-to-center column distance from your manual (typically 10–11 ft) and snap a chalk line across the floor as your alignment guide. Both base plates must align precisely with this line.

Stand and position the columns

Raise each column with an assistant — they're heavy. Align each base plate with the chalk line. Have your assistant hold the column plumb while you mark your drill points through the base plate holes.

Step 2 — Drill Anchor Holes and Set the Bolts

Drilling is the noisiest, dustiest part of the job. Wear your dust mask and ear protection throughout.

Use the base plate holes as your drill guide. Work the bit up and down to fully clear each hole, then blow out all dust — concrete dust in the hole significantly reduces anchor holding power.

Insert the anchor bolts and tap them down until the washer is flush against the base plate. Do not fully tighten yet. Level the column using your 4-foot level, adding horseshoe shims under the base plate as needed (max shim thickness: 2¼ in.). Once plumb, torque to 85 ft-lbs. Repeat for the second column, then re-check the first column's torque.

Step 3 — Raise and Install the Top Trough

With both columns anchored, it's time to lift the overhead connecting bar (top trough) into position. You have two options:

• Two ladders + two people: One person on each side raises simultaneously, slides the bar into the column bracket slots, and bolts from the top.
• Forklift: If you still have one from delivery day, use it — especially on heavier 14,000 lb+ lifts.

Once the top trough is bolted, re-check all column anchor bolts one more time. Installation vibration during this step can loosen them.

Step 4 — Install the Hydraulic Power Unit

The hydraulic power unit mounts to the main column at mid-height. A vibration dampener pad goes between the unit and the column — never skip this; it prevents fastener loosening over time.

Once mounted, fill the reservoir with approximately 3.5 to 4 gallons of ISO 32 Light Hydraulic Oil (confirm exact capacity in your manual). Wrap all hydraulic fittings with Teflon tape before connecting, and check for leaks after the first test cycle.

Step 5 — Route Cables, Lines, and Hoses

This step varies most between manufacturers — follow your manual closely. You'll route and connect:

• Equalizer cables — through the cylinders and over pulleys in each column, keeping both carriages synchronized during raise and lower
• Safety cables — lock carriages in place if hydraulic pressure is lost
• Hydraulic lines — connect the power unit to both cylinders
• Power unit hoses — connect the reservoir to the pump

Take your time. A misrouted equalizer cable will cause uneven raising and binding under load. If something feels wrong during your first test cycle, lower immediately and trace the cables before continuing.

Step 6 — Install and Test the Lift Arms

Lift arm installation is typically the simplest part. Slide each arm into the carriage slot and insert the headpin through the arm and carriage hole. Then:

1. Install the snap ring into the headpin groove on the underside of the carriage.
2. Confirm each arm is in the correct left/right configuration.
3. Verify the Arm Restraint Gear Ring teeth mesh cleanly with the Pin Assembly on each arm — these are the locks that hold the vehicle at height.
4. Tighten the gear ring bolts.
5. Swing each arm left and right by hand and feel for solid, smooth engagement at every position.

First Test Run Checklist

Before any vehicle goes on the lift, do a full no-load test cycle:

1. Raise to full height. Listen for grinding, popping, or uneven hydraulic sounds.
2. Visually confirm both sides rise at the same rate. If one lags, re-check equalizer cable routing and tension.
3. Check every hydraulic fitting for leaks. Wipe dry and recheck after a second cycle.
4. Lower fully and confirm both carriages descend at the same rate.
5. Test the safety latches — raise to mid-height, let the safeties engage, and try pushing the carriage down by hand. It should not move.

Once everything checks out, load with a light test vehicle and repeat. Inspect all anchor bolts and base plates after the first loaded raise.

A proper installation takes 3–5 hours with two people. If anything feels wrong, stop and call a certified installer — the cost of a service call is nothing compared to a drop event.
