Recent analyses of precision low energy electroweak data indicate that the deviation from the Standard Model predictions of the measurement of atomic parity violation ( ), the effective number of massless neutrinos (), and Ab ( ) could be better described if the existence of an extra Z' neutral gauge boson is assumed. We investigate the implications of a 300-00 GeV/c2 extra Z' on current collider data at TeV, including the forward-backward charge asymmetry for very high mass e+e- pairs, and the invariant mass specstrum of high mass e+e-, , and pairs. For example, a 500 GeV/c2 Z' with a total production cross section of and enhanced coupling to the third generation, better describes both the low energy and the Tevatron data.
