I have the ones for for my heavy BPP Truggy (Based on the Hot Bodies Truggy) and it works good as it's harder then the white ones from HB. Now I also bought that one on the link for my MBX5T and it's not as hard as the one for the HB. I have the red MBX5T springs on the truggy now and it's harder.

Even harder ones are Hobao's grey truggy springs.
lutach what springs are you using on BPP Truggy? Id need abit harder springs for my truggy and have hard time finding harder ones.

I'm using the ones from Reckward Tuning for the HB Lightning Stadium, but they are really extra hard. The extra hard ones I got for my MBX5T are much softer and I went back to the red Mugen ones.

so the mugen red springs are the hardest?

I have the Reckward Tuning Extra hard, the blue Mugen, but the red one is harder and it's what I've been using. If you feel that your spring is not hard enough, just preload it to the way you want, but sometimes your vehicle will bounce too much and thicker oil should be used.

time for some x2 big bores
