What are you running?

**Mega internals fit the MEGAmulti only.** The multi adapter guide tube, crank housing and cylinder liner are exclusive to it. Not compatible with any other model.

**A REDIboss78 sleeve does not fit a REDIclassic52.** One tube is 3 1/8", the other is 2". They are cut differently, and a sleeve for the wrong tube will not seat.

### Fitment questions

Only if the post is narrower than the guide tube. A sleeve keeps the post centred so it drives straight. Rods and rebar always need one, a 13/16 inch sleeve, on every model.

No. The MEGAmultiguidetube, MEGAcrankhousing and MEGAcylinderliner are exclusive to the MEGAmulti and are not compatible with any other model. Going the other way, the four REDIboss78 reducer sleeves (1 3/4", 13/16", 2 1/2" and 2 1/4") also fit the MEGAmulti. For every other part, the compatibility matrix shows exactly which drivers it fits.

No. REDIboss78 sleeves are cut for the 3 1/8 inch guide tube. The REDIclassic52 has a 2 inch guide tube and takes its own sleeves, such as the REDIslvrod52poly for rods rather than the REDIslvrod78poly.
