RR swivel cup

[dirtracer2a]

Im looking to put a swivel spring cup on the rr of my bmod, but most I find say only use for the front. Will they work or what one should I use?

I had swivel cups on the back of our old super stock/sportsman and I believe it just helps with equal loading of the spring. That's my thoughts on it.

Im just wondering why the ones I find at places like speedway and such say only for use on the front.

I think I used the bsb ones before. I can't remember though.

you can use them on the rear if the thread is the correct size. The reason Speedway says use on front only is because IMCA Northern Sportmods do not allow a swivel cup to be used on rear.

BSB does make a nice lightweight one with a teflon lined com ball
