TR7 High Ratio Steering Rack. Fully reconditioned using all new parts. 2.75 turns lock to lock, a must for all competition cars. Obviously this does make the steering slightly heavier if driving on the road.
I am always looking to buy used RHD steering racks with casting number BEX3018 cast into the pinion housing. There is a £40 surcharge if you do not have an exchange rack as they are getting hard to find.
