The Video SK2 centerpost contains old BNC connectors that do not support HD signals.
Upgrading the SK2 centerpost to HD requires removing all old wiring and lemo connectors that link the centerpost to the sled base, then making new connections at that junction point.
Centerpost HD upgrade work demands advanced soldering and wiring skills, and improper execution risks damaging original components.
The SK2 base has threaded holes at its lowest point beneath a protective cap that can be used for attaching additional weight or extensions.
Extending the centerpost length is mechanically difficult and requires a specialist experienced with steadicam equipment.
A Provid arm can be created by combining two SK single arms, but modifications should only be made at the joints, never by disassembling the closed moving segments of the arms.
The closed arm segments contain dangerous forces and attempting to disassemble them without proper knowledge can cause serious injury or death.
Some SK2 sleds have been successfully modified with hybrid configurations using both SD and HD signal lines by installing junction boxes at the top and bottom of the centerpost.

The described upgrade procedures are complex and carry high risk of damaging components if not executed by someone with expert soldering and mechanical skills.
Centerpost extension has not been confirmed as fully successful and may not be achievable depending on the specific base design.
The arm modification procedure carries serious safety risks and should only be attempted by trained professionals.
Specific compatibility details between SK2 components and Provid components are not fully detailed.
