4 ton floor jack

Four ton capacity equals 8,000 lb [3,629 kg]. That is the maximum rated lift. It is not a support rating. Use jack stands after lifting.

This page explains the 4 ton floor jack class with sizes and lift range and safe use. You get dual units on every figure. Native unit first and the conversion in brackets.

What 4 ton means

A floor jack is a lifting device. It raises part of the vehicle. It does not hold the load for work. After the lift place jack stands under maker approved points and lower the load onto the stands.

Capacity is the rated lift at the saddle. Four ton means up to 8,000 lb [3,629 kg]. One lift point carries a share of the curb weight. A 6,000 lb [2,722 kg] SUV can place about 1,500 to 3,000 lb [680 to 1,360 kg] on one corner depending on balance. The 4 ton rating covers that use when you follow the manual.

Materials and features that matter

Steel or aluminum

Steel frames are durable. Aluminum frames cut weight for easier moves. Both can meet the same capacity when built to the standard.

Handle length

Longer handles give easier lifts and keep you clear of rocker panels. Check two piece handles for a firm joint.

Saddle pads

Use a rubber pad for pinch weld lifts when the maker allows it. A U slot pad can help on pinch welds.

Safety valve

Overload valves stop unsafe lifts. They do not replace stands.

Safe use in one page

Read the jack manual and the vehicle manual
Use level concrete and wheel chocks on the ground
Set the parking brake before any lift
Center the saddle on the maker approved lift point
Lift only enough to place stands at the same height
Lower the load onto stands rated for the job
Never work under a vehicle that sits on a jack

FAQ

Is 4 ton enough for a full size truck: Yes for lifting one corner or one axle when you follow the manual. The jack raises part of the weight. Use stands for support.
Can I use this on asphalt: Use a firm level surface. Asphalt can soften in heat. Use thick plywood under the jack and under stands if the surface is not concrete.
Do I need jack stands with a 4 ton jack: Yes. A floor jack is for lifting. Stands are for support. The standards and the manuals require stands for any work.
Are jack stand ratings per stand or per pair: Labels vary by maker and region. Some rate per pair. Some rate per stand. Read the label on your stands and follow the manual.
Is aluminum safe for trucks: Yes when the rating matches the task and the jack meets the standard. Check minimum saddle height and maximum lift for your frame.
