suspension
 

what would be better for parts. ive heard that rpm is good and ive never had a problem with them as ive got rpm bulkheads, a arms front and rear, ball cups, and reciever cover. but im looking for new shock towers, should i go rpm or aluminum.

I would go with RPM, their plastics are extremely durable. That way if you break one they'll replace it free, no questions asked.

there is questions asked u have to write out a form and send it with part 99% of the time they will replace it but i have had that 1% part they didnt replace

what didnt they replace. ive heard they will like both you said but there is always that chance they wont. so im curiuos what you had a problem with.
