Default Mag. Model differences

Can anyone explain the differences between a slick model 4371/4372/4373?

Many thanks

Default Lag

Seems a prominent difference is the degrees of lag

Looks like they are all impulse mags. 4371 has 20 deg lag, 4372 has 15 deg lag, and 4373 has a 25 deg lag. I guess their use would depend on your engine timing.

Hey all, I thought that I would revive this thread.

I am not the OP but have a question on the topic.

I see that these mags only differ in the amount of lag, so, given that... if you have a good 4371 and want to make it a (experimental only) 4373, would that be as simple as changing the impulse coupling from the 4373 onto the 4371?

Are the internals of the mags identical and do they only differ by the impulse coupling?
