Supertech Titanium Retainer Kit - BMW S85 Engine

Regular price $558.80 USD
Regular price Sale price $558.80 USD

These Suptertech Titanium Retainers for the S85 BMW engine are a great addition to the Supertech or BE Valve Spring setups. The titanium retainer takes the place of the heavier steel retainer reducing valve train weight and allowing the engine to rev more freely. The stock retainer weighs in at 6.1 grams while the titanium retainer from Supertech is only 4.3 grams. If you are considering a high rpm S85 engine build using some Schrick cams, these retainers would be a great upgrade for you.

These can also be added to our Stage 1 or Stage 2 cylinder head builds without any additional labor costs.
