"How do I protect the Porsche parked underneath from oil drips?"
You've entered the accessories and add-ons phase. This is where a basic lift transforms into a complete, versatile, and safe workspace.
At garagesuppliesus.com, we stock every component and accessory you need to maximize your lift's utility. This guide is your complete catalog of car lift accessories—from essential lift jack tray for 4 post setups to replacement car lift power unit components.
🛠️ Part 1: 4-Post Lift Essential Accessories
Lift Jack Tray for 4 Post: The Game Changer
This is the #1 searched accessory for 4-post lift owners: "lift jack tray for 4 post."
The Problem:
A standard 4-post lift is a storage lift. The car sits on its tires on the runways. You cannot remove the wheels to do brake work or suspension repairs.
The Solution:
A rolling jack tray (also called a bridge jack) slides between the two runways. You place a bottle jack or a dedicated rolling jack on the tray, position it under the car's frame or differential, and lift the wheels off the runways.
Types of Lift Jack Tray for 4 Post:
| Type | Capacity | Price Range | Best For |
|---|---|---|---|
| Standard Sliding Jack Tray | Holds bottle jack (varies) | $150 – $300 | DIY occasional use |
| Manual Rolling Bridge Jack | 3,500 – 4,500 lb | $600 – $900 | Weekend mechanic, tire rotations |
| Air/Hydraulic Rolling Jack | 4,500 – 7,000 lb | $1,200 – $2,500 | Professional shop, frequent use |
| Dual Rolling Jack Set | Two jacks, synchronized | $2,500 – $4,000 | Full undercarriage access, alignments |
Compatibility Warning:
Not every lift jack tray for 4 post fits every brand. The runway width and inner lip design vary between manufacturers. Always verify compatibility with your specific lift model before ordering.
The garagesuppliesus.com Recommendation: For home 4-post owners, the manual rolling bridge jack is the sweet spot. It provides professional capability (lifting entire front or rear axle) at a reasonable price point.
Car Lift Ramps Extension: Low Car Solutions
This search—"car lift ramps extension"—comes from owners of lowered cars, sports cars, and exotics.
The Problem:
Standard 4-post lift approach ramps are steep. A Corvette C8 or Porsche 911 GT3 will scrape its front splitter before the tires even touch the ramp.
The Solution:
Extended-length, low-angle approach ramps. These are longer (usually 48" – 60" instead of 36") and have a gentler incline.
Car Lift Ramps Extension Options:
| Type | Length | Price Range | Best For |
|---|---|---|---|
| Standard Ramps (Included) | 36" | Included | Normal ride height vehicles |
| Extended Ramps | 48" – 60" | $200 – $400 | Lowered sports cars, exotics |
| Race Ramps (Composite) | 67" – 80" | $350 – $600 | Extremely low cars, show cars |
| Ramp Extenders (Add-On) | +12" – +24" | $100 – $200 | Budget solution for occasional use |
Pro Tip: If you have multiple vehicles with different ride heights, buy Race Ramps composite extensions. They're lightweight, won't scratch floors, and can be stacked/stored easily when not in use.
Lift Drip Trays: Protecting Your Investment
This search—"lift drip trays"—is essential for anyone parking a valuable car underneath another car on a 4-post lift.
The Problem:
The car on top leaks. Even well-maintained cars have residual oil on the undercarriage, condensation from the exhaust, or small fluid seeps. That drips onto the roof, hood, or windshield of the car parked below.
The Solution:
Drip trays (also called catch pans or oil trays) slide between the runways of a 4-post lift and catch falling fluids.
Lift Drip Trays Options:
| Type | Material | Price Range | Best For |
|---|---|---|---|
| Single Solid Tray | Galvanized Steel | $80 – $150 | Basic fluid catching |
| Multi-Panel Tray System | Aluminum / Plastic | $150 – $300 | Full coverage of entire vehicle footprint |
| Magnetic Drip Trays | Plastic with magnets | $40 – $80 | Temporary use, easy removal |
| Custom Fit Trays | Matched to lift brand | $200 – $400 | Perfect fit for BendPak, Atlas, etc. |
The garagesuppliesus.com Recommendation: For long-term storage, invest in a multi-panel aluminum drip tray system. It covers the entire underside of the top vehicle and won't rust like galvanized steel.
Car Lift Wheel Stops: Safety First
This search—"car lift wheel stops"—is about preventing a catastrophic mistake.
The Problem:
On a 4-post lift, you drive onto the runways. If you drive too far forward, the car goes off the front of the lift and crashes to the ground.
The Solution:
Wheel stops (also called chocks or parking stops) bolt to the front end of the runways. They physically prevent the vehicle from rolling forward.
Car Lift Wheel Stops Options:
| Type | Material | Price Range | Best For |
|---|---|---|---|
| Standard Steel Stops | Powder-coated steel | $40 – $80 | Most 4-post lifts |
| Adjustable Stops | Steel with sliding mount | $80 – $150 | Varying vehicle lengths |
| Rubber Stops | Heavy-duty rubber | $30 – $60 | Protecting low-profile tires/wheels |
| LED Illuminated Stops | Steel with LED guide lights | $100 – $200 | Low-light garages, precision parking |
Installation Note:
Most car lift wheel stops bolt directly to pre-drilled holes in the runway. If your lift didn't include them (some budget models don't), they are an essential safety add-on, not optional.
🔧 Part 2: Hydraulic System & Power Components
Lift Hydraulic Oil: The Lifeblood of Your Lift
This is a frequently searched maintenance term: "lift hydraulic oil."
The Problem:
Hydraulic oil degrades over time. It absorbs moisture, collects debris, and loses viscosity. Using the wrong oil can damage seals, cause cavitation, or void your warranty.
The Correct Lift Hydraulic Oil Specifications:
| Oil Type | ISO Viscosity Grade | Common Names | Best For |
|---|---|---|---|
| AW-32 | 32 | Anti-Wear Hydraulic Oil 32 | Standard for most 2-post and 4-post lifts |
| AW-46 | 46 | Anti-Wear Hydraulic Oil 46 | Hot climates, heavy commercial use |
| Dexron III ATF | N/A | Automatic Transmission Fluid | Some older lifts (check manual) |
| ISO 22 | 22 | Thin hydraulic oil | Cold weather operation |
The Golden Rule:
Always check your lift's owner's manual for the exact oil specification. Using AW-32 in a lift that requires AW-46 can cause overheating and pump damage.
How Much Lift Hydraulic Oil Do You Need?
| Lift Type | Reservoir Capacity | Approximate Cost (5 Gallons) |
|---|---|---|
| 2-Post Lift (10,000 lb) | 2.5 – 3.5 Gallons | $35 – $50 |
| 4-Post Lift (8,000 lb) | 3.0 – 4.0 Gallons | $40 – $60 |
| Scissor Lift | 1.5 – 2.5 Gallons | $25 – $40 |
| Heavy-Duty 12,000 lb+ | 4.0 – 5.0 Gallons | $50 – $75 |
When to Change Your Lift Hydraulic Oil:
-
Initial Fill: New lift installation.
-
Annually: If lift is used commercially (20+ cycles/day).
-
Every 3-5 Years: Home garage use.
-
Immediately: If fluid appears milky (water contamination) or dark/gritty (debris).
garagesuppliesus.com stocks: AW-32 and AW-46 hydraulic oil in 1-gallon and 5-gallon containers. We also stock biodegradable hydraulic oil for environmentally sensitive locations.
Car Lift Power Unit: The Heart of the System
This search—"car lift power unit"—indicates a major component failure or a DIY builder sourcing parts.
The Problem:
Your lift motor hums but won't run. Or it's leaking fluid from the pump housing. Or it's 20 years old and you want a modern, quieter unit.
Car Lift Power Unit Components:
| Component | Function | Replacement Cost |
|---|---|---|
| Electric Motor | Drives the hydraulic pump | $200 – $400 |
| Hydraulic Pump (Gear Pump) | Pressurizes fluid | $150 – $300 |
| Reservoir Tank | Holds hydraulic fluid | $50 – $150 |
| Solenoid/Release Valve | Controls lowering speed | $40 – $100 |
| Complete Power Unit Assembly | Motor + Pump + Tank + Valve | $400 – $900 |
Car Lift Power Unit Specifications to Match:
| Specification | Common Values | What Happens If Wrong |
|---|---|---|

Lift Installation Kit: What's Included?
This search—"lift installation kit"—is often from buyers who purchased a used lift that didn't come with hardware, or who need replacement anchors.
What's in a Complete Lift Installation Kit:
| Component | Quantity | Purpose |
|---|---|---|
| Wedge Anchors | 10-14 (per lift) | Secure columns to concrete floor |
| Anchor Setting Tool | 1 | Properly seats wedge anchors |

Replacement Wedge Anchors:
If you're moving a lift or installing a used lift, never reuse old wedge anchors. They are designed for one-time installation. The wedge mechanism deforms during initial torque and will not hold properly a second time.
Standard Wedge Anchor Sizes:
| Lift Capacity | Anchor Diameter | Anchor Length | Embedment Depth |
|---|---|---|---|
| 7,000 – 9,000 lb | 3/4" | 5-1/2" | 3-1/4" minimum |
| 10,000 – 12,000 lb | 3/4" or 7/8" | 6" – 7" | 4" minimum |
| 15,000 lb+ | 1" | 8" – 10" | 5" minimum |
🛡️ Part 3: Safety & Adaptability Components
Car Lift Safety Locks: The Non-Negotiable Component
This search—"car lift safety locks"—is about the most critical safety feature on any lift.
The Problem:
Hydraulic systems can fail. Hoses burst. Seals blow. If the hydraulics fail while a car is in the air, the mechanical safety locks are the only thing preventing a catastrophic fall.
Types of Car Lift Safety Locks:
| Type | How It Works | Common On |
|---|---|---|
| Ladder Lock (Slack Cable) | Spring-loaded pawl engages notches in column ladder | Most 2-post lifts |
| Slack Cable Lock | Cable tension holds lock open; loss of tension triggers lock | Premium 2-post lifts |
| Runway Lock (4-Post) | Steel pins or cams engage posts at each corner | All 4-post lifts |
| Secondary Lock | Redundant backup system | ALI Certified lifts |
Signs Your Car Lift Safety Locks Need Attention:
-
Slow to engage: Grease the pivot points.
-
Don't engage at all: Broken spring or bent lock bar. STOP USING THE LIFT.
-
Uneven engagement: One side locks, the other doesn't. Cable adjustment needed.
-
Grinding noise: Lock pawl is dragging on column. Adjust or lubricate.
Replacement Car Lift Safety Locks:
-
Ladder Lock Pawl Assembly: $40 – $120 (varies by brand).
-
Lock Release Cable: $25 – $60.
-
Lock Spring Kit: $15 – $30.
The garagesuppliesus.com Safety Statement: Never disable, bypass, or modify car lift safety locks. If a lock component is broken, stop using the lift immediately and order replacement parts. We stock safety lock components for all major brands.
Lift Arm Extensions: Reaching Difficult Frames
This search—"lift arm extensions"—comes from owners of trucks, vans, and vehicles with unusual frame configurations.
The Problem:
Standard lift arms are designed for passenger cars. When you try to lift a lifted pickup truck, a Sprinter van, or a classic car with a boxed frame, the standard arms and screw pads don't reach the lifting points.
Types of Lift Arm Extensions:
| Type | Purpose | Price Range |
|---|---|---|
| Tall Screw Pad Adapters | Extra height for trucks/lifted vehicles | $40 – $100 per set |
| Frame Cradle Adapters | Wide contact for boxed frames | $60 – $150 per pair |
| Unibody Adapters (Pinch Weld) | Protect unibody pinch welds | $30 – $60 per set |
| Arm Extension Sleeves | Extend reach of existing arms (rare, brand-specific) | $100 – $300 per arm |
| Magnetic Adapter Pads | Quick-attach for odd shapes | $40 – $80 per set |
Compatibility Critical:
Lift arm extensions are highly brand and model specific. The diameter of the arm tube, the thread pitch of the screw pad, and the locking pin mechanism vary between manufacturers. Always verify compatibility before ordering.
Common Lift Arm Extension Scenarios:
-
Lifted Ford F-250: Needs 6" – 8" tall screw pad adapters.
-
Mercedes Sprinter Van: Needs frame cradle adapters with wide, flat contact surface.
-
Tesla Model 3: Needs unibody pinch weld adapters to prevent battery pack damage.
-
