Transmission Primary 9 upgrade for saab 900 classic

Did you noticed how inadequate is the saab classic 900 gear ratio? First gear is really too short as the second gear. The RPM is too high at a constant speed which is not good for the reliability of the transmission and for the driving experience.

Transmission Primary 9 upgrade by RBM performance will offer you the best driving experience on your classic 900

More and more of our clients use their fast Saab 900 Classic on a daily basis and we see an increase in transmission related problems. Used components, especially the much sought after “primary 8” upgrade, are scarce, expensive and often of questionable quality. Besides that, the existing problem of running high rpm numbers at highway cruise speeds is still not adequately solved either.

Here an effective solution for these issues. An upgrade that gives you the same pace at lower rpm for relaxed cruising and comes with a higher top speed in one go. Lower rpms reduce the wear and tear of your engine and transmission and positively affect fuel consumption as well. This upgrade makes the Saab 900 Classic even more suitable for everyday use.

In comparison to Saab Original parts:

Primary Gear 6                   – 4000rpm – 140km/h – Vmax at 6500rpm = 227.5km/h*
