Challenger RJ7X — 7,000 lb Air/Hydraulic Rolling Jack for Scissor Lifts

The Challenger RJ7X is a 7,000 lb capacity air/hydraulic rolling jack engineered specifically for the Challenger SX14 and SX14R series scissor lifts. Rail-mounted and foot pedal operated, the RJ7X rolls along the scissor lift's accessory rails to position under each axle, giving technicians free-wheel access for brake, tire, and suspension work. The included FLR (filter, lubricator, regulator) assembly connects to your shop's compressed air supply via a standard ¼ NPT quick disconnect coupling.

Key Specifications & Operation

The RJ7X lifts from a lowered height of approximately 2.75 inches to a raised height of 12.625 inches. The extendable lift pad arms reach from 33 inches (retracted) to over 50 inches (extended) at center, allowing precise positioning under factory lift points. The air/hydraulic pump is activated by a foot pedal and delivers 7,000 lb of lifting capacity (3,500 lb max per arm/pad) at 5,200 PSI hydraulic pressure. A mechanical lock secures the jack at the raised position. Two 3-inch stack extensions are included for trucks and SUVs. Maximum air operating pressure is 150 PSI.

Compatibility & Installation

The RJ7X is compatible with Challenger SX14 and SX14R series scissor lifts equipped with accessory rails. It is not interchangeable with rolling jacks designed for 4-post lifts (RJ7.5, RJ9, RJ15) due to the different rail geometry on scissor lifts. Installation requires mounting the jack assembly on the lift rack rails and securing it with four hex bolts (two per side). An internal airline kit (sold separately) is required to route compressed air to the rolling jack positions. The RJ7X is sold individually.

Before You Buy

Scissor Lift Only

This rolling jack is designed exclusively for Challenger SX14 and SX14R series scissor lifts. It is NOT compatible with 4-post lifts. For 4P14, 4015, and 4115 series lifts, see the RJ7.5 rolling jack.

Air Supply Required

The RJ7X requires a compressed air supply (max 150 PSI) for operation. An air compressor is not included. An internal airline kit (sold separately) is required to route air to the rolling jack positions.

Sold Individually

This rolling jack is sold as a single unit. Most setups use two rolling jacks (one per axle). Order quantity of 2 for a complete set.

Frequently Asked Questions

The Challenger RJ7X is compatible with Challenger SX14 and SX14R series scissor lifts equipped with accessory rails. It is NOT compatible with 4-post lifts — use the RJ7.5 for 4P14, 4015, and 4115 series lifts instead.
The RJ7X is designed for SX14 series scissor lifts with a 7,000 lb capacity. The RJ7.5 is designed for 4P14, 4015, and 4115 series 4-post lifts with a 7,500 lb capacity. They are not interchangeable due to different rail geometry.
The RJ7X requires compressed air connected via a standard ¼ NPT quick disconnect coupling. Maximum air operating pressure is 150 PSI. An internal airline kit (sold separately) is required to route air to the rolling jack positions on your scissor lift.
The RJ7X lifts from approximately 2.75 inches (lowered) to 12.625 inches (raised). Extendable center lift pad arms reach from 33 inches retracted to over 50 inches extended.
Yes, two 3-inch stack extensions are included. Optional 6-inch (10355-6) and 9-inch (10355-9) stack extensions are available separately for greater reach on trucks and SUVs.
The RJ7X is sold individually. Most scissor lift setups use two rolling jacks (one per axle) for complete free-wheel access. Order a quantity of 2 for a complete set.
