Triumph Tr5/Tr6/Gt6/Vitesse Performance
Valve Spring Retainers

Complete set of 12 No. performance lightweight alloy valve spring retainers that are suitable for the Triumph TR5, TR6, GT6 MkI, II & III, Triumph Vitesse, Triumph 2000 & 2500S or indeed any car fitted with a Triumph 6 cylinder engine.
The standard valve retainers fitted originally to the above vehicles were made of steel and worked ok and many owners still have them fitted to their engines. However, today many classic Triumph owners & driver's want more performance out of their original engines and the modifications and upgrades available come in many forms, these alloy valve spring retainers are one of those modifications.
The principal is simple yet ingenious. The fitting of these lightweight alloy caps reduces the valve loading applied when operating at high revs and therefore saves wear on the camshaft lobes. The weight saving achieved is approximately 50% as compared to using the original steel valve spring retainers. The engine will rev more freely due to the action of reciprocal force i.e. with steel retainers there is more weight resistance and this restricts the revving capabilities of the engine. The alloy retainers equal less weight for the camshaft to lift therefore yielding freer engine revving.
The alloy retainers are supplied in a kit of 12 and will suit either the single or double valve spring arrangement, there is no need to replace the original springs, the retainers are simply held in place by the original split collets. It is however recommended that the spring retainers are replaced in sets of 12 rather than individually and the fitting of them is very easy. It can be done by any competent Triumph enthusiast within a short period of time with nothing more than your standard workshop tools.
For reference, these valve caps are British made and are manufactured from Grade 7075 aluminium which is very strong and is commonly used in the aerospace industry for its strength. These valve caps are a must for the classic Triumph racing enthusiast or those owners simply wishing to add a touch of performance to their engines.
