The AlKo 1300 is designed for trailers up to an MTPLM of 1360kg and 100kg noseweight. The 3004 is OK up to 3000kg and 150kg noseweight. Performancewise there is no other difference.

I thought that the 1300 only worked on side to side motion so has only one pair of pads and the 3004 also damped up down motion as well as the side to side motion so has two sets of pads.
