10315 Stack Truck Adapter Kit For Challenger Lifts
This stack adapter kit is designed for two-post Challenger lifts and related models, providing height extensions to accommodate running boards, side steps, or other pickup points. The set allows stacking to achieve 3, 6, or 9 inches in height, enabling safer, more stable lifts where reach is a limiting factor. Crafted from high-strength #45 steel, the adapters balance durability with manageable weight, and their design supports a load capacity around 12,000 lbs, suitable for a range of trucks and larger vehicles.
Atesilor 4 Pcs 60mm Lift Adapter Set
The 4-piece kit raises lift feet by 3 inches and uses high-strength #45 steel with sandblasting for corrosion resistance and a rated load of 12,000 lbs. Each adapter has a 60mm pin diameter and is compatible with 2-post lifts, bridge jacks, and lift pads featuring a 60mm hole. It is particularly suitable for Challenger 2-Post Lifts, with guidance to verify the mounting hole diameter before installation to ensure a secure fit.
Aumtoni Auto Lift Adapter For KATOOL Two-Post Lifts
Designed for Katool two-post car lifts, this adapter focuses on vehicle protection and stability. It features rubber padding to reduce scratches on trucks and SUVs while providing tactile pads that minimize slipping. The product targets a high load-bearing capacity range and emphasizes safe lifting operations with a focus on finish protection during pallet-like lifts.
4 Pack Truck Adapter For 2 Post Lift
Hot-dip galvanized steel construction delivers corrosion resistance and durability. The set includes four adapters with a 60mm pin diameter and a standard M36 bottom thread, compatible with Challenger and several other two-post lifts. A rotating anti-damage design with a 360° self-balancing support head helps correct center-of-gravity offsets, reducing the risk of frame deformation when lifting uneven or modified vehicles.
QuickJack SUV and Light Truck Adapter Kit
This set adds 6 inches of lifting height specifically for SUVs and light trucks used with QuickJack TL and TLX models. The four adapters are designed for QuickJack’s lift system to extend reach safely and efficiently, broadening the range of vehicles that can be serviced with this setup. Compatibility notes indicate optimization for QuickJack’s TL/TLX line, providing a practical upgrade where additional height is needed.
Atesilor 2 Pcs Upgraded 60mm Lift Adapter
This 2-piece 60mm adapter set offers a 3-inch height increase with robust #45 steel construction and corrosion resistance via sandblasting. It is designed for 2-post lifts with a 60mm hole, with advice to verify the hole diameter prior to installation for a secure fit. The compact kit suits garages needing quick, incremental height enhancements for precise alignment during lifts.
Atesilor 6pcs 60mm Stack Truck Adapter Kit
The 6-piece kit includes four 3-inch adapters and two 6-inch adapters, plus storage racks and screws. This flexible set enables 3/6/9 inch height combinations for Challenger 2-Post Lifts and similar systems. As with other Atesilor products, it uses #45 steel with corrosion-resistant finishing and a 12,000 lb load rating, designed for demanding shop environments and varied vehicle shapes.
Buying Guide: Key Purchase Considerations
- Compatibility: Confirm whether adapters fit your lift brand and model (Challenger, ME, KA, KT, or QuickJack TL/TLX). Check diameter (60mm is common) and bottom thread size (M36) to ensure a proper match.
- Height Increase vs Weight Capacity: Decide how much additional height you need (3″, 6″, or 9″) and verify the combined weight capacity remains within the lift’s limits for your typical vehicle mix.
- Material and Finish: Look for high-strength steel (e.g., #45) with corrosion-resistant finishes. Hot-dip galvanization adds durability in harsh workshop environments but may increase weight.
- Pad Protection and Slippage: Rubber pads and anti-slip surfaces protect finishes and help prevent slipping during lifting, especially with trucks and SUVs.
- Storage and Organization: Sets with racks or organized storage help keep adapters neatly arranged, reducing misplacement and improving workflow in busy shops.
- Installation Considerations: Some adapters require removing a retaining ring or verifying mounting hole diameters before installation. Ensure you have the appropriate tools and follow safety guidelines.
- Safety Certifications and Load Testing: Look for adapters tested to handle heavy loads (commonly 12,000 lbs) and that they meet applicable safety standards for automotive lifts.
When selecting adapters, balance the need for additional clearance with the lift’s structural limits and the specific pickup points on vehicles you service. A mix of shorter 3-inch and taller 6-inch options often covers a wide range of use cases, from running boards to frame rails, while keeping payload within safe limits.
