If it aint broke don't fix it. Even if it could help you by making a change it is really not going to affect your ranking very much. Some things you can do.
1. as always build more links not only to front page but to internal pages.
2. Make sure your content is unique. If your using descriptions from manufacture rewrite them. Work on interlinking your internal pages like wikipedia does. Each product page should link to other product pages using good keywords in anchor text.
