'04 EB Explorer; struts and Sirius
 

I want to replace the F&R struts on my '04 EB Explorer (105K miles) and was wondering if the EB package included heavy duty shocks / springs. My Explorer has the larger (2") factory towing receiver. I'd like to keep the stock EB ride quality and don't want a lift.

Since the shocks and coil-over springs are sold separately, should I replace both or use the original springs?

My Explorer has the factory 6-CD changer / subwoofer and a SAT button. I have an add-on Sirius radio that transmits to an unused FM freq on my radio, but I was wondering if there is a factory Sirius kit and if it is worth the money to install it. Just added the factory Sirius kit to our '09 Subaru Legacy and it was far better than the add-on options.

Thanks for any advice you may have.
