6-Inch Stack Extensions for High-Clearance Vehicle Service - Challenger Rolling Jack Accessories (10355-6)
Trucks, SUVs, and lifted vehicles often sit too high for standard rolling jack pads to reach factory lift points. The Challenger 10355-6 stack extensions solve this problem by adding 6 inches of height to your RJ6 or RJ7.5 rolling jack. Sold as a matched pair, these extensions work with Challenger 4-post lift systems to give technicians proper undercarriage access during wheel service, brake jobs, and suspension repairs.
Designed as genuine Challenger Lifts accessories, the 10355-6 extensions feature drop-in installation that requires no modifications to your existing rolling jack setup. When properly installed, the extensions maintain full compatibility with the RJ6's 6,000 lb capacity and the RJ7.5's 7,500 lb capacity.
Key Features and Benefits
Exact-Fit Compatibility - Engineered specifically for Challenger RJ6 and RJ7.5 rolling jacks, eliminating the fitment guesswork associated with universal or aftermarket adapters.
Drop-In Installation - Installs directly into the existing rolling jack adapter interface without tools or permanent modifications, reducing setup time between service jobs.
Complete Matched Set - Package includes two 6-inch extension adapters, providing everything needed for a single rolling jack without separate purchases.
Applications
- Reaching factory-recommended lift points on trucks, SUVs, and vans.
- Servicing vehicles with running boards or lifted suspensions.
- Brake service and rotor replacement on high-clearance vehicles.
- Tire rotation and wheel service within 4-post lift ecosystems.

Frequently Asked Questions
Will the Challenger 10355-6 stack extensions fit other rolling jack brands?
No, the 10355-6 extensions are designed exclusively for Challenger RJ6 and RJ7.5 rolling jacks. They are engineered as OEM accessories with exact-fit dimensions for these specific models and will not work with rolling jacks from BendPak, AMGO, Atlas, or other manufacturers.
How do the 10355-6 stack extensions install on my rolling jack?
The extensions use a drop-in design that fits directly into the existing rolling jack adapter interface. No permanent modifications or special tools are required. Simply position the extensions in the rolling jack receiver before lifting the vehicle.
What is the difference between the 10355-6 and 10355-9 extensions?
The 10355-6 provides 6 inches of additional height, while the 10355-9 provides 9 inches. Both are sold as pairs and fit the same Challenger RJ6 and RJ7.5 rolling jacks. Choose based on your typical vehicle clearance requirements.
Do the stack extensions reduce the rolling jack weight capacity?
When properly installed, the 10355-6 extensions maintain full compatibility with the parent rolling jack capacity ratings - 6,000 lbs for the RJ6 and 7,500 lbs for the RJ7.5. Always follow Challenger Lifts installation guidelines.
