Ranger RFJ-4000ALX 4,000 lb Aluminum Racing Floor Jack

The Ranger RFJ-4000AL (and 4000ALX equivalent) is a high-performance aluminum racing floor jack built for serious garages, performance shops, and track enthusiasts. Engineered to handle tough jobs while remaining lightweight and easy to maneuver, this jack blends strength, agility, and safety in one efficient package.

Rated for a lifting capacity of 4,000 lbs, this jack is very well suited and capable to lift most passenger cars, performance vehicles, light trucks, and sports cars. The all-aluminum construction keeps the unit light and portable, while still providing durability under load. The jack’s body is crafted from aircraft-grade billet aluminum, ensuring long life without excessive weight.

One of the standout advantages of this floor jack is its low profile and small footprint that preserves garage space. It begins with a minimum saddle height of 3.75 in (95 mm), allowing it to slip under low-clearance cars and performance vehicles. When fully extended, it reaches a maximum saddle lift height of 19 in (487 mm), enabling ample undercarriage access for maintenance, inspections, and repairs. The compact overall length of 26 in (660.5 mm) maintains maneuverability in tight workshop spaces, while the rear width sits at 12.4 in (315 mm), front width at 11.33 in (288 mm), and body rear height of 6.5 in (165 mm). The total weight of the unit is about 56 lbs (25.4 kg). 

To make jacking smoother, the jack includes a dual-piston pump system that reduces pumping effort and speeds up lift time. The alloy-plated ram and double-sealed hydraulic system resist contamination and wear, extending service life and maintaining performance consistency. A built-in safety overload valve prevents hydraulic overload, guarding against misuse or overloading beyond capacity. 

The jack’s front features a low-profile, single-piece roller that helps with alignment and stability under the vehicle. The oversized knurled aluminum handle provides a secure grip and enhanced control during operation. Swivel casters add to mobility, letting you move the jack smoothly around the shop floor or into tight spaces. 

Safety and ease of use are key. The built-in overload protection ensures you don’t accidentally lift beyond safe limits. The precision machining ensures minimal play or wobble under load. The jack’s design also makes it easy to set up, stow, and position even in confined bays or trailers.

Maintenance of this floor jack is straightforward. Keep the piston and ram clean and lubricated, periodically bleed air from the hydraulic system, inspect seals and the overload valve, and ensure the swivel casters and roller are free from debris. Proper storage and periodic checks will keep the jack reliable for years.

For shops, track support units, or serious home garages, this Ranger aluminum racing floor jack strikes a balance between performance and practicality. It allows fast, smooth lifts with minimal effort, supports high weight capacity, and offers portability. If you’re looking to upgrade your lifting gear or outfit a professional shop with a reliable, strong, and precise floor jack, this model stands out.
