LiftMaster K41-0063-000 Drive Sprocket, HD Slide
The LiftMaster K41-0063-000 drive sprocket is a factory replacement part for the HD slide gate drive system. The sprocket works with the operator chain drive to transfer motion from the internal drive train to the gate movement assembly.
A worn sprocket can cause the chain to ride poorly, skip, chatter, or wear faster than normal. On high-cycle commercial slide gates, a sprocket with hooked, chipped, or uneven teeth can create repeated service problems even after a chain replacement.
This part is most commonly listed for the HDSL24UL heavy-duty slide operator. Some listings and parts references may mention related industrial slide platforms, but final compatibility should be verified by the operator parts diagram and original sprocket configuration.

Technician Note
When a sprocket is replaced because of tooth wear, inspect chain stretch and alignment at the same time. Installing a new sprocket on a badly worn chain can shorten the life of the new part.
Before Ordering Checklist
- Confirm the operator is HDSL24UL or a confirmed HD slide variant.
- Compare the original sprocket part number to K41-0063-000.
- Inspect the chain for stretch, rust, stiff links, or uneven wear.
- Check sprocket alignment and shaft condition before installation.
- Confirm gate movement is smooth and not overloading the drive system.
Professional Advisory
Drive sprocket service should be performed with power disconnected and the gate secured. A qualified gate technician should inspect the full drive train after replacement.
Important Ordering Warnings
- Not a universal drive sprocket.
- Do not order by tooth appearance alone.
- Sprocket wear is often connected to chain misalignment, gate drag, or worn bearings.
Product Questions and Answers
Is K41-0063-000 a drive sprocket or limit sprocket?
K41-0063-000 is commonly listed as the HD slide drive or output sprocket service kit, not the limit reduction chain.
Which LiftMaster model commonly uses this sprocket?
The clearest compatibility is LiftMaster HDSL24UL heavy-duty slide gate operators.
Should the chain be replaced with the sprocket?
If the chain is stretched, rusted, stiff, or worn into the old sprocket teeth, replacing or servicing the chain at the same time is recommended.
Can this be used on IHSL24UL or INSL24UL?
Only if the parts diagram for that exact operator calls for K41-0063-000. Some references mention industrial HD slide families, but confirmation is required.
What problems can a worn drive sprocket cause?
Chain jumping, noisy movement, rough travel, uneven chain wear, and loss of proper drive engagement can all point to sprocket or chain wear.
