Radiator Caps

Raceparts is the UK distributor for Stant and Motorad racing radiator caps and can offer a great range of products for both 4 and 2 wheel competition.

Please note that Stant racing radiator caps are no longer manufactured, whilst some models are still in stock most have been replaced by the Motorad R-Spec and Motorad's standard racing range.

The Motorad R-Spec have been specifically designed, developed and manufactured for the motorsport market. They are designed for maintaining the optimal pressure allowing the coolant to withstand higher temperatures. This gives better cooling performance whilst keeping engines performing efficiently and safely. The manufacturing of the Motorad R-Spec range is done with the intense vibrations, maximum heat and heat cycles of motorsport competition in mind.

Motorad's standard racing range are automotive rad caps which have been adapted for competition use. This range of radiator caps offers great value for money.
