Frequently Asked Questions
Q: How does the SU S820-A compare to the SU S820 and SU S820-XL models?
A: The SU S820-A is a variant designation in the Superior S820 load wheel family. It is compatible with the SU S820 and SU S820-XL base wheels and uses the same 20 mm axle and 82 mm diameter. Verify your truck documentation to determine if the -A variant is the correct replacement for your specific serial range or if you should use the standard SU S820-XL instead.
Q: Can I interchange SU S820-A with SU S820-XL on the same truck?
A: Yes, SU S820-A and SU S820-XL are interchangeable if they share the same axle bore (20 mm) and wheel diameter (82 mm). However, do not mix variants across the front and rear axles unless Superior service documentation explicitly allows it. Always replace wheels in sets (all four or both front/rear pairs) to maintain balanced handling and prevent differential wear.
Q: What should I check before ordering SU S820-A to ensure correct fitment?
A: Verify the lift truck model and serial number. Measure the spindle bore diameter (should be 20 mm) and wheel diameter (should be 82 mm). Check the truck nameplate or Original manual for the correct part number. Contact Superior parts support with your truck model and serial range to confirm that SU S820-A is the approved replacement, not SU S820-XL or another variant.
