Clutch and brake master cylinder adjustable push-rods

Saturday, 27 January 2018 11:57 Product News
If you own and drive an older Lotus vehicle then its quite likely the clutch and brake pedals will have some unwanted free-play.
This may not be immediately apparent but can be checked by pulling the pedal backwards and up towards the seat.
If there is excessive free-play then it can change the correct operating point on the clutch and brake pedals.
An easy way of correcting this problem is to install adjustable master cylinder push-rods.

Lotus Esprit and Excel upper gasket set A912E9228W

Monday, 23 October 2017 17:53 Product News
The following gasket set suits allnormally asperated Lotus Esprit and Excel SE and SA models from mid-year 1986 onwards.
NOTE - The manifold and cam cover gaskets are manufactured from a high quality material based on a blend of Aramid and inorganic fibres bonded with a nitrile rubber filler.
This gasket material exceeds the operational requirements of the Lotus Esprit 912 engine and can withstand operating temperatures of 300 degrees Centigrade. 
Unlike the original Lotus components, these gaskets are impervious to oil and water so there is no possibility of capillary action taking place between the cylinder head and inlet manifold.

The cylinder head gasket is manufactured from a high quality composite material that can withstand the extremes of constant temperature cycling.
The head gasket is 1.5mm (0.060") thick with a silicon peripheral sealing bead plus surface coating that guarantees a water and oil-tight seal.

Lotus Elan 2+2 steering rack tie-rod

Friday, 03 February 2017 10:55 Product News
These high quality tie-rods have been fully CNC machined to the original dimensions and thread sizes which make them completely interchangeable with any Lotus Elan 2+2 steering rack. Unlike our competitors, we choose not to zinc plate and passivate the tie-rods entirely so as to offer corrosion resistance. Installing a zinc plated ball into a hardened retaining cup is going to instantantly contaminate the ball joint with unwanted zinc material. The correct choice of corrosion protection for the tie-rod, is to apply epoxy paint to the exposed shaft section only.

Diameter of the ball is 1.040 inches (26.41mm) and length from end of threaded section to underside of the ball is 5.85 inches (148.60mm)
Overall length is 7.0 inches (177mm aproximately)
Detail for tie-rod end is 1/2 UNF x 20 TPI and the thread length is 2.0 inches (50.8mm)
Material is 4140 high tensile steel alloy, and the ball is heat-treated to produce a high quality component.
There is a tapered transition from the threaded section to shank that eliminates stress failure.
There is an additional groove on the tie-rod that prevents the rubber gaiter from moving when fastened.
Individual component weight 230 grams
