Pair of 5th gears to suit DS or SM gearbox.
Extra high ratio of .625:1 (same as C35 ratio - 40:25 teeth).
With these gears and standard ratio final drive, the engine is doing approx 2500rpm at 70mph in 5th gear.
Ideal if you have a noisy 5th gear or just want more relaxed motorway cruising, and the best bit is that 5th gear can be changed without removing the gearbox from the car.
These are brand new parts made in the UK.
