Conversion Kit to upgrade the wiper system to replace the notoriously poor standard Motor and Wheelbox with a Heavy Duty Motor and Wheelboxes. The kit Includes all fittings and Instructions. TR4 and TR4A Wiper Systems are notoriously poor and can be frankly dangerous when they are worn out.

Rather than replacing the wiper system with standard parts (some of which are unavailable and some are dodgy reproductions), why not consider this upgrade.

The kit includes a Heavy Duty Wiper Motor, Mounting Bracket (see note), Heavy Duty Wheelboxes and Tubes & Fittings. Once installed the new system will give two speeds and Self Park and the ability to incorporate our intermittent wiper control kit, see below.

The switch included in this kit is a late TR6 rotary type which will accommodate a TR4-4A type knob with a hexagon shaft and has the added advantage of incorporating a push switch for electrical washers. Other switches are available, see below.  

Note : - This mounting bracket is provided painted with a light coat of black paint for storage purposes only as the bracket is usually painted car colour when fitted to the body work
