Key Features and Benefits of the Challenger EW10SS Superstructure

Extra-Wide 88-Inch Drive-Thru Clearance for Modern Vehicles

The EW10SS superstructure provides an 88-inch drive-thru clearance that is specifically engineered to accommodate wide-bodied vehicles, electric vehicles, and exotics that cannot safely fit on standard-width inground lifts. This extra-wide clearance handles vehicles like the RAM TRX, Hummer EV, Tesla Model X, and Ford Mach-E without risk of tire pinching or bolster contact during positioning.

Standard-width inground lift superstructures with 87-inch or narrower drive-thru clearances can damage tires, wheels, and body panels on today's wider vehicles during the spotting process. As vehicle widths continue to increase across all segments, the extra clearance provided by the EW10 wide platform becomes increasingly important for shops servicing a diverse vehicle mix.

This enables your shop to confidently accept and service the widest vehicles on the road today while maintaining full compatibility with standard-width cars and trucks. The no-bolster-to-drive-over design further simplifies vehicle positioning and reduces the risk of undercarriage damage during entry and exit.

EV-Ready Design for Battery Lowering Operations

The EW10SS superstructure is part of a lift platform designed to support battery lowering operations on electric vehicles. The extra-wide clearance and arm geometry allow technicians to safely lower EV battery packs through the service bay floor, a capability that is becoming essential as electric vehicle adoption accelerates and battery service becomes a routine part of automotive maintenance.

Standard-width inground lifts do not provide the clearance needed for battery lowering procedures, forcing shops to invest in separate specialty equipment or turn away EV battery service work. The EW10 platform addresses this limitation by integrating battery lowering capability into a conventional inground cassette lift format.

This future-proofs your service bay investment by ensuring the lift can handle both traditional vehicle service and emerging EV maintenance workflows without requiring additional specialized equipment or bay modifications.

True 3-Stage Arms for Maximum Vehicle Coverage

The EW10SS includes true 3-stage front and rear arms that provide access to manufacturer-recommended lift points on a wide range of vehicles from compact cars to full-size trucks and wide-bodied SUVs. The triple-telescoping design delivers a 2,500 lb capacity per arm, giving technicians the flexibility to safely contact OEM pickup points across the broadest range of vehicle types including those with specific or hard-to-reach lift point locations.

Standard 2-stage arms have a more limited reach range that can make it difficult to access lift points on certain vehicle types, particularly wider vehicles with outboard pickup points common on modern EVs and luxury platforms. The 3-stage design eliminates this limitation by offering both more extension and more retraction than competitive 2-stage arm configurations.

This maximizes your shop's revenue potential by expanding the range of vehicles you can service in each bay, including the growing segment of electric and wide-bodied vehicles that require the extra clearance and reach of the EW10 platform.

Double-Telescoping Screw Pads with Extended Height Range

The superstructure comes equipped with double-telescoping screw pads adjustable from 4 inches to 6.125 inches, providing a wider height adjustment range than single-stage pads for accommodating diverse vehicle pickup point configurations. This dual-adjustment capability reduces the frequency of needing separate stack adapters to reach vehicle lift points.

Single-height fixed pads require technicians to constantly swap adapters for different vehicle types, adding time to each vehicle positioning cycle. The double-telescoping design builds height adjustment directly into each contact pad, covering more vehicle lift point heights within the standard pad assembly.

This speeds up vehicle spotting and reduces adapter handling time, which is particularly valuable in high-volume service environments. The extended 4-inch to 6.125-inch range ensures compatibility with the varied pickup point heights found across modern vehicles including EVs with battery-protected underbody structures.

OEM EW10 Platform Compatibility

The EW10SS is engineered specifically for the Challenger EW10 (EW1020) 10,000 lb capacity wide inground cassette-style lift system. This ensures proper dimensional fit with the EW10 bolster mounting points, correct arm pin alignment, and proper clearance specifications when installed on the EW10 platform.

Attempting to use superstructure components from a standard-width lift model (such as the EV1020) or a different capacity rating will not provide the correct drive-thru clearance, arm geometry, or mounting dimensions for the EW10 wide platform. The EW10SS eliminates these risks through factory engineering that matches the specific tolerances of the EW10 system.

This enables shops to replace or install superstructure components with confidence that the completed lift will operate within its original safety and performance parameters while maintaining the full 88-inch drive-thru clearance that defines the EW10 wide platform.

Applications and Use Cases for the Challenger EW10SS Superstructure

  • Superstructure Replacement: Replace worn, damaged, or outdated superstructure components on an existing EW10 wide inground lift with factory-specified 3-stage arm assemblies that restore original performance and the full 88-inch drive-thru clearance.
  • New EW10 Installations: Provide the above-grade lifting interface for a new EW10 wide inground lift installation when purchased separately from the completion kit and lower cassette tub components.
  • Electric Vehicle Service Bays: Equip service bays dedicated to EV maintenance with the wide-body superstructure that supports battery lowering operations and accommodates the wider chassis dimensions of modern electric vehicles.
  • Dealership and Luxury Service Centers: Service wide-bodied luxury vehicles, performance trucks, and exotics with the extra clearance needed to prevent cosmetic damage during vehicle positioning.
  • Multi-Brand Service Facilities: Maximize bay versatility by installing a superstructure that handles both standard vehicles and the growing segment of wide-bodied and electric vehicles on a single lift platform.
