The engagement of the Overdrive gear is hydro-electrical. The overdrive is operated by the flick of a switch, whilst engagement is restricted, for design reasons, to top gear.
In addition the complete installation can be removed at any time, leaving absolutely no trace.Įach Laycock unit is produced to order with a matched speedometer drive ratio.
The kit is easily fitted, replacing the existing prop-shaft, and in most cases there is no need for drilling, welding or the re-routing of ‘one-shot’ pipes or the existing wiring harness. Rubber mounts and silent blocks are used, in a configuration designed to limit oscillation/ vibration, insulate the overdrive and eliminate the transmission of noise. The Nostalgia Cars UK Ltd overdrive package utilises the tried and tested Laycock unit, suspended or mounted depending on your vehicle on a substantial cross-member system.
