What is a superstructure and what does it include? ▾
The superstructure is the above-ground vehicle contact assembly for an inground lift. The EV1020SS includes 3-stage front and rear versymmetric arms, 4 double telescoping screw pads, 4 standard adjustable screw-type extensions, 4 medium extensions, 2 high extensions, and 4 frame engaging truck adapters. These are the components that physically contact and lift the vehicle at its designated pickup points.
What lift system is this superstructure compatible with? ▾
The EV1020SS is engineered exclusively for the Challenger EV1020 10,000 lb inground cassette-style lift system. It is not compatible with the EV1220, EV1520, EW Series, or competing manufacturers' inground lifts. The EV1220 uses the EV1220SS superstructure, which has different arm specifications and a higher per-arm capacity rating.
How many superstructures do I need? ▾
One EV1020SS superstructure is required per lift unit. If you purchased a set of 2 EV1020 lifts (LS-2 model), you will need 2 separate EV1020SS superstructure kits. If you purchased an EV1020 Upper Components (UC) package, the superstructure is already included and this product is not needed.
What other components do I need for a complete lift? ▾
A complete EV1020 installation requires three component groups: the CSPK-series pre-kit foundation (sealed polymer cassette pit), a completion kit (EV10CK variants providing pistons, power unit, and controls), and this superstructure. If you already have the pre-kit and completion kit installed, the EV1020SS is the final component needed for a fully operational 10,000 lb inground lift.
What does "versymmetric" mean? ▾
Versymmetric refers to Challenger's arm design that enables both symmetric and asymmetric lifting within the same service bay. Symmetric lifting positions all four arms equidistant from center, while asymmetric positioning shifts the vehicle forward or rearward to provide better door clearance or access to specific undercar areas. This dual capability eliminates the need for separate symmetric and asymmetric arm sets.
What is the arm reach range? ▾
The 3-stage arms adjust from a minimum reach of 19.625" to a maximum of 42.125". This range accommodates compact cars with closely spaced lift points through full-size trucks and SUVs with wide-set pickup points. Challenger's triple-telescoping design provides more extension and more retraction than competitive arm designs for broader vehicle coverage.
What are frame engaging truck adapters used for? ▾
Frame engaging truck adapters (Part 10314 or 10318) are required when lifting vehicles with frame construction, such as trucks, body-on-frame SUVs, and vans. The adapters hook onto the vehicle frame rails to provide secure contact points. Four frame engaging adapters are included with the EV1020SS. Unibody vehicles use the standard screw-type extensions instead.
What color options are available? ▾
The EV1020SS superstructure is available in Red, Blue, or Black powder coat finish. The durable finish resists chipping and corrosion in active service environments. Specify your preferred color at the time of order. Contact our sales team if you need to confirm color availability or match an existing installation.
How do the double telescoping screw pads work? ▾
The double telescoping screw pads adjust from 3.875" to 6" in height, providing a wider range of contact heights than single-stage pads. This extended adjustment range minimizes the frequency of needing separate truck adapters by reaching a broader set of manufacturer-designated pickup points. The heavy-duty polyurethane construction provides secure, non-damaging contact with vehicle lift points.
What is the difference between the EV1020SS and EV1220SS? ▾
The EV1020SS is rated at 2,500 lb per arm (10,000 lb total) for the EV1020 lift, with arm reach from 19.625" to 42.125". The EV1220SS is rated at 3,000 lb per arm (12,000 lb total) for the EV1220 lift, with arm reach from 19.625" to 48". The two superstructures are not interchangeable between lift platforms due to different mounting configurations and load ratings.
Is professional installation required? ▾
Professional installation by qualified lift technicians is required for the complete EV1020 system. The superstructure mounts to the completion kit components and must be assembled, adjusted, and tested according to Challenger's installation manual. Proper arm alignment and extension verification are critical for safe operation and warranty coverage.
What warranty coverage does the superstructure include? ▾
Challenger provides a 5-year warranty on structural arm components and a 2-year warranty on functional parts including extensions and adapters. Warranty coverage requires proper installation according to manufacturer specifications and use within the rated 2,500 lb per arm capacity. Registration must be completed within 30 days of installation at challengerlifts.com.
