Rotary Lift® 3” Polymer Jack Adapter | FJ2428

Essential Rotary FJ2428 – 3” Polymer Jack Adapter for Rotary Lifts

The Rotary FJ2428 is a heavy‑duty 3-inch polymer jack adapter engineered to enhance the safety, versatility, and lifting performance of Rotary automotive lifts. Commonly referred to as a spotting block, lift spacer, or stack block, this adapter provides additional lift height while protecting vehicle undercarriages from damage during service. Designed for everyday use in professional shops, the FJ2428 is a go‑to adapter for technicians working on vehicles with low ground clearance, side steps, running boards, or delicate rocker panels.

Manufactured from reinforced polymer, the FJ2428 delivers high-strength durability, excellent surface grip, and long service life under demanding shop conditions. Whether you’re using a Rotary two-post lift, four-post lift, rolling bridge jack, or low-rise lift, this adapter helps ensure consistent, stable contact at the lift points—reducing risk and improving technician confidence on every job.

Designed for Professional Automotive Lifting

The 3-inch height profile of the Rotary FJ2428 makes it particularly valuable for modern vehicles, including crossovers, EVs, and SUVs, where factory lift points may sit above standard pad height or require a taller contact surface. This added height gives technicians the clearance they need without compromising safety or stability.

For dealership service managers, this adapter supports OEM lifting requirements and reduces the risk of underbody damage—an essential factor for warranty repairs. For independent shop owners, it provides a cost‑effective solution for lifting a wider range of vehicles without investing in new arms, adapters, or specialty lifting equipment.

Why Technicians and Service Managers Rely on the FJ2428

Professional technicians, dealership managers, and growing independent shops all rely on lifting accessories that ensure vehicle safety and maximize efficiency. The Rotary FJ2428 is built around the demands of real-world automotive service environments:

1. Increased Versatility
Shops face an array of vehicle sizes and chassis designs. This adapter gives you the height needed to accommodate difficult lift points, EV battery trays, and custom vehicles.

2. Vehicle Protection
Its rubberized polymer material helps protect factory undercoating, painted surfaces, running boards, and step bars from damage—key for maintaining customer trust.

3. Consistent Lift Point Contact
Technicians work faster and safer with stable, predictable contact at every lift. This reduces slip risk and overall wear on lift arms and pads.

4. Shop Efficiency
Adapters like the FJ2428 drastically cut down on repositioning time. Your technicians can lift vehicles correctly the first time, boosting bay productivity.

5. OEM-Trusted Quality
As a Rotary-engineered component, this jack adapter aligns with OEM lifting specifications and integrates seamlessly with Rotary lift systems.

Ideal Applications

The Rotary FJ2428 is suited for a wide range of automotive service tasks, including:

• Brake and suspension repairs
• Tire and wheel service
• General undercar inspections
• Alignment preparation
• Lift point height adjustments for lifted trucks, EVs, SUVs, and low-profile cars

Shops that service many different vehicle types often keep multiple sets of FJ2428 adapters to ensure maximum flexibility.
