We extend results by B. Hasselblatt, J. Schmeling in \emph{ Dimension product structure of hyperbolic sets} (2004), and by the third author and K. Simon in \emph{ Hausdorff and packing measures for solenoids} (2003), for $C^{ 1+\varepsilon}$ hyperbolic, (partially) linear solenoids $\Lambda$ over the circle embedded in $\mathbb{ R}^3$ non-conformally attracting in the stable discs $W^s$ direction, to nonlinear ones. Under an assumption of transversality and assumptions on Lyapunov exponents for an appropriate Gibbs measure imposing \emph{ thinness}, assuming also there is an invariant $C^{ 1+\varepsilon}$ strong stable foliation, we prove that Hausdorff dimension ${ \rm HD}(\Lambda\cap W^s)$ is the same quantity $t_0$ for all $W^s$ and else ${ \rm HD}(\Lambda)=t_0+1$. We prove also that for the packing measure $0<\Pi_{ t_0}(\Lambda \cap W^s)<\infty$ but for Hausdorff measure ${ \rm HM}_{ t_0}(\Lambda\cap W^s)=0$ for all $W^s$. Also $0<\Pi_{ 1+t_0}(\Lambda) <\infty$ and ${ \rm HM}_{ 1+t_0}(\Lambda)=0$. A technical part says that the holonomy along unstable foliation is locally Lipschitz, except for a set of unstable leaves whose intersection with every $W^s$ has measure ${ \rm HM}_{ t_0}$ equal to 0 and even Hausdorff dimension less than $t_0$. The latter holds due to a large deviations phenomenon.
