Stronger gear options for 5 speed fs5w60l?

[Surfez]

Anyone know if you can buy replacement 1st and 2nd gears for a sunny b310 5 speed gearbox? not a dog box...Wanting to give it some strength after fitting the high performance a15.

There was a rally kit available for the dogleg five speeds, but they cost MOONBEAMS.
The 60 series boxes are pretty strong. Unless you have a turbo, or a blower, it should hold up to the abuse.

I think cusco do a kit, but expensive as Bart said. Usually they get custom made. And usually done to change gear ratios more than add strength.

All good thanks guys, will assemble it as is and hope she lasts... Have heard they take a fair share of torque.

I Used to habitually abuse my 60 series 5 speed behind my supercharged A15. and it never missed a beat.
