Valve Spring Retainers by JMB Services

To fit DB4, DB5, DB6 & DBS Aston Martins


At JMB Services we make, in-house, a full range of custom valve spring retainers for Aston Martins DB4, DB5, DB6, DBS & V8. The retainers are made from a high grade EN16 material for maximum strength and durability.

We also make Grade 5 titanium retainers for race use or for those that want the best there is. JMB Services special tappet type also available. We keep a small stock of Titanium valve spring retainers for Aston Martins but are usually a 'made to order' component.
