Abstract: A radial position control assembly for a gas turbine engine includes a case structure. A support structure is operatively supported by the case structure respectively with first and second splines in engagement with one another. The support structure includes an annular recess, and a support ring is received in the recess. The support structure and the support ring having different coefficients of thermal expansion. An axial biasing member urges the first and second splines into engagement with one another.
