If the spring is too long that would happen. Also check if you used the right end caps. The front end caps are thicker than the rear end caps.

The shock bodies are not rubbing against the H-Arm because i use the MEDIUM 4.8mm Ball end (is this what you called the 'end cap' ?) Yes, if i use the SMALL 4.8mm Ball end with the Lower hole, that will rub against the H-ARM.
However, the manual for this Kit (GRP Wide Sponge & swaybars version) indicates that i should use the MEDIUM 4.8mm ball end.
