Km baja shocks , replace or rebuild ?

[snapon]

My km baja shocks seem pants and im sure ive read that most are not filled correctly from new ? Is it worth replacing or just checking/replacing the oil and maybe springs ? The rear just dont bounce back , fronts seem ok . If replacing oil can anyone recommend which oil to use front and rear and where to purchase ? Same goes for springs , cheers

I'd check them first before replacing them. If the rears aren't rebounding, either the oil is too thick or your springs are too soft.

The recommended oil is 15w front, 45w rear IIRC.

30w up front and 5wt in the rear. 45w would be like a pogo stick and wouldn't comprress. Use fork oil, not silicone oil. I have no idea why to use fork oil, but that's what HPI recommends.

Silicone oil eats at the seals hpi use

I had 40 rear and 5 front at one point which actually worked fairly well until I started doing large jumps, then it broke the shock pistion in half

I now run 30 front and 10 rear which does much better but has a habit of scrapping the ground when the going gets rough

When I next come to shock inspection, a job I hate with a passion, I'll be filling it with 35 front and 25 rear which shoul be enough for my normal running needs
