Brass (1/4") is the heavy weight, typically used as lower links for good vehicle balance. It typically slides better then aluminum.
High Clearance Option:
The high clearance option gives you a bend on the links to help clear obstacles. You may find on certain vehicles this will leave your drive shaft more exposed to damage. Some folks will put spacers between the link and rod end to achieve to clock the driveshaft upwards out of the way.
D-links uses the Traxxas revo rod ends with our product. They have proven to be reliable and long lasting. We do sell replacement rod ends in case you wear yours out.
D-Links are made in the U.S.A. All D-Links are lifetime guaranteed. Send in the broken link and receive a brand new one. We can not guarantee the rod ends as they are a wear item and very between brands.
Q:Why don't we do aluminum?
A: Aluminum tends to grab at rocks and stick to them. It also bends fairly easily, for this reason we don't do aluminum links. If you are wanting light, Delrin will slide better and hold up better then aluminum and is super light.
Q: Why not stainless, doesn't it weigh the same as brass?
A: Stainless and brass are similar in weight, however we found that brass seems to slide better over obstacles.
*Note* D-Links are made to order and could take up to 3 weeks to be completed. Turn Around is usually faster, but please allow some time for quality.
