Rotary FC5781-7 Extended Ramp Chocks for SM30 Lifts - 73-inch Length Pair
The Rotary FC5781-7 Extended Ramp Chocks increase total ramp length on SM30 and SM300-200 series four-post lifts, reducing approach angle during vehicle loading. This pair of extended drive-on ramps features an oil-resistant, non-skid surface engineered for traction and safety in professional automotive service environments.
Key Features & Benefits
Extended Ramp Length for Low-Clearance Vehicle Loading
The extended ramps add 33 inches of additional length beyond standard SM30 ramps, bringing total ramp length to 72–73 inches. This extended profile reduces the driving approach angle when loading vehicles with low ground clearance, minimizing the risk of bumper damage or vehicle contact during the initial drive-on phase.
Professional automotive shops frequently handle low-clearance passenger vehicles, sports cars, and modified vehicles that struggle with standard ramp geometry. Traditional ramps force steep approach angles that risk cosmetic or structural damage before the vehicle reaches the lift platform. Extended ramps address this industry-wide challenge by providing a gradual incline that accommodates aggressive vehicle underbodies.
This enables safer loading of performance and luxury vehicles by reducing the steep initial approach angle. Technicians can guide low-clearance vehicles onto the ramps smoothly without concern for bumper strikes or undercarriage contact, improving operational efficiency and reducing vehicle damage claims.
Oil-Resistant, Non-Skid Drive Surface
The ramp surface features a specialized non-skid coating with oil resistance engineered to maintain traction in oily shop environments. The textured surface prevents tire slippage during drive-on and drive-off operations, while the oil-resistant properties resist degradation from floor fluids, hydraulic leaks, and common shop contaminants.
Automotive service bays generate constant fluid exposure from engine fluids, transmission oils, and hydraulic leaks. Standard smooth ramp surfaces become slippery under these conditions, creating safety hazards when vehicles drive onto lifts. Oil-resistant coatings address this challenge by maintaining consistent traction regardless of floor contamination.
This improves operator confidence and vehicle stability during loading and unloading operations. The non-skid texture grips tire tread reliably, reducing the likelihood of wheel slippage that could damage the vehicle or injury risk to nearby technicians. The extended surface life of oil-resistant coating reduces replacement frequency.
Purpose-Built Compatibility with SM30 and SM300-200 Series Lifts
These ramps are manufactured specifically for Rotary SM30 and SM300-200 series four-post lifts, with engineering that matches OEM ramp specifications and mounting geometry. The design ensures proper fitment, alignment, and balanced load distribution across the lift platform without modifications or adapter hardware.
Generic or multi-fit ramp accessories often create alignment issues, improper seating, or uneven weight distribution on four-post lifts, compromising lift performance and safety. Purpose-built accessories designed for specific lift series eliminate these compatibility concerns by matching exact OEM specifications and mounting interfaces.
This ensures installation confidence and proper load handling without fitment surprises. The ramps integrate seamlessly with your existing SM30 or SM300-200 lift system, maintaining warranty compliance and lift performance specifications throughout their service life.
Pair Configuration for Balanced Load Distribution
This product ships as a complete pair (2 ramps) to ensure balanced installation across both lift columns. The matched pair prevents uneven weight distribution that can occur when ramps have different surface conditions, wear patterns, or structural characteristics.
Traditional single-ramp or mismatched replacements create asymmetric load paths on four-post lifts, stressing one side more than the other. This imbalance can accelerate column wear, compromise lift stability, and create safety risks during vehicle positioning. Matched pair configurations address this challenge by maintaining symmetric load distribution.
This enables proper lift performance and extends component longevity by distributing vehicle weight evenly across all four lift columns. The balanced pair approach supports safer, more stable vehicle handling during the critical loading and unloading phases of lift operation.
Applications & Use Cases
- Low-Clearance Passenger Vehicle Service: Loading sports cars, performance vehicles, and modified vehicles with aggressive stance geometry or lowered suspension that requires extended ramp approach angles.
- Commercial Automotive Service Bays: Professional multi-bay shops performing routine service on mixed vehicle classes, where low-clearance vehicles are processed alongside standard-height vehicles on the same lift system.
- Professional Garage Environments: Fleet service facilities and dedicated specialty shops requiring reliable, repeatable ramp performance for consistent vehicle positioning and lift operation across high-volume service operations.

Frequently Asked Questions
What is the total ramp length of the FC5781-7 extended ramp chocks for SM30 lifts?
The FC5781-7 extended ramp chocks provide 72–73 inches (1,829–1,854 mm) of total ramp length, adding 33 inches (838 mm) beyond standard SM30 ramps. This model ships as a pair (2 ramps) and is designed exclusively for Rotary SM30 and SM300-200 series four-post lifts.
Which Rotary lift models are compatible with the FC5781-7 extended ramp chocks?
The FC5781-7 extended ramp chocks are designed specifically for Rotary SM30 and SM300-200 series four-post lifts. The pair includes 2 ramps with a combined length of 72–73 inches and is not compatible with other lift models or brands. Verify your lift series before ordering to ensure proper compatibility.
Why do extended ramp chocks help with low-clearance vehicles?
Extended ramps increase the total length of the drive-on surface from standard SM30 geometry to 72–73 inches, which reduces the approach angle that vehicles must navigate when loading onto the lift. This gentler slope accommodates low-clearance vehicles with aggressive suspension geometry or modified stance without risking bumper strikes or undercarriage contact during the initial drive-on phase.
What surface treatment do the FC5781-7 ramp chocks have?
The ramp surface features an oil-resistant, non-skid coating that maintains traction in oily shop environments. The FC5781-7 pair is designed for Rotary SM30 and SM300-200 series lifts, delivering 72–73 inches of length with textured surface that prevents tire slippage during drive-on and drive-off operations while resisting degradation from engine fluids, hydraulic leaks, and common shop contaminants.
Why do these ramp chocks come as a pair rather than individual ramps?
The matched pair configuration ensures balanced load distribution across both lift columns on SM30 and SM300-200 series four-post lifts. Using mismatched ramps or individual ramp replacements creates asymmetric load paths, which can stress one side more than the other and compromise lift stability. The FC5781-7 pair maintains symmetric weight distribution during vehicle loading and unloading operations.
Can I mix the FC5781-7 extended ramps with standard SM30 ramps?
No. The FC5781-7 extended ramp chocks (2-ramp pair, 72–73 inches total length) must be installed and used together as the matched pair provided. Do not substitute individual ramps or mix with standard SM30 ramps or other ramp accessories, as this compromises balanced load distribution and lift stability. Always install the complete pair on both ramp positions.
What warranty coverage is included with the FC5781-7 ramp chocks?
The FC5781-7 pair includes warranty coverage that varies by authorized dealer, with standard terms ranging from 90 days to 1 year from date of purchase. Coverage includes defects in materials and manufacturing under normal use conditions on SM30 and SM300-200 series four-post lifts. Verify specific warranty terms and registration requirements with your dealer at the time of purchase.
