Factory-Direct Heavy-Duty Jacks

Higher Lifting Capacity

Most common air/hydraulic jacks are rated at 22 US tons. Our JR-80/40 model is rated at 80/40 metric tons— more lifting power and a larger safety margin for heavy-duty truck service, fleet maintenance, and roadside tire work.

Rated at 80/40 metric tons vs. standard 22-ton jacks
Larger safety margin for heavy-duty truck service and fleet maintenance
Backed by warranty if jack fails under normal use within rated capacity

80/40 Tons vs. Standard 22 US Tons — Up to 73% More Lifting Capacity

Lower Minimum Height

The JR-80/40 has a minimum height of only 7.5 inches, while many standard 22-ton jacks are around 8.5 to 9.75 inches. For even lower clearance, our 3-stage low-profile model can go as low as 6.5 inches.

7.5" minimum height vs. 8.5"–9.75" on standard 22-ton jacks

Even with a fully loaded heavy truck stranded roadside with a flat tire — our jack fits under, lifts up, no problem.

7-Inch Ram Stroke for Better Lifting Range

Our standard ram travel is 7 inches, compared with many typical 22-ton jacks that offer only about 5 to 5-5/8 inches of travel. The longer stroke gives mechanics more usable lifting range.

7" ram stroke vs. 5"–5-5/8" on typical 22-ton jacks
More usable lifting range per lift cycle
Reduces the need for repositioning during the job

Safer Controlled Lowering

Our jack requires compressed air to lower. Without air supply, the lifting piston will not suddenly descend — even if the external air line or components are disconnected.

Air-required lowering — no accidental descent
Piston stays in place even if air line is disconnected
Added safety layer for professional operators

Piston Will NOT Drop Without Air Supply — Built-In Safety by Design

Solid Jack, Great Service — Bought More This Year

Love this jack. I bought my first one last year at the Mid-America Trucking Show, and I came back and bought more this year. The quality is solid, it works great for truck service, and the jack feels much more stable and reliable than a lot of others I’ve used. Customer service has also been excellent — very responsive and helpful. Great product, great service, and definitely worth the money. Highly recommend.

Perfect

Perfect jack – still solid as new after one-two year of use.

Perfect

I purchased this jack specifically to replace my Harbor Freight 22-ton hydraulic jack. In terms of build and functionality, it works great. So far, it’s the most reliable jack I’ve bought — and the price is unbeatable.

Good truck Service Floor jack

Bought this jack from them 2 years ago — still solid and strong. Reaches max height in 15 seconds. Never had any issues so far, but I accidentally damaged the switch and they sent me a new one for free. Love it

Great Buying Experience — Solid Jack for Farm Equipment!

I first saw this jack at the Mid-America Trucking Show and was immediately impressed. I bought one on the spot and brought it back to my store — no regrets at all. The jack is heavy-duty and works perfectly for lifting some of our larger farming equipment.
I liked it so much that I went ahead and purchased another standard air hydraulic jack from JRAIRTOOLS — both products were delivered within 4 days. Great customer service, solid quality. Highly recommend for anyone in trucking or agriculture!

Huge Upgrade from Standard Jacks — This One’s a Beast!

We’ve been using a basic 22-ton jack for years, but decided to give JR AIR TOOLS a shot when they offered us a 1-month free trial on their air hydraulic jack. And honestly? We’re impressed.

Right out of the box, it felt more solid and well-built. The lift is smooth, powerful, and surprisingly fast. We put it to work during the trial period and ended up loving it so much, we didn’t want to send it back.

If you're in the market for a reliable, heavy-duty hydraulic jack, this is the one to get. Great support from JR AIR TOOLS, and the free trial gave us full confidence in switching over.
