Mini Spares has just introduced a new competition valve cotter with a large single groove for early Mini heads.

The cotters are precision CNC-machined from 4340 steel and heat-treated to a higher specification than EN24T to resist fatigue and make them more durable under race conditions.

The large single groove design provides a better location around the valves and makes it easier to control spring heights.

The cotters are designed to be used with the original top caps (88G616). They can be used with small single groove top caps (88G617), but the cotters will sit about 20 thou higher; this will be fine for standard use.

Order as part number 2A11EVO at £4.75 each inc. VAT.
