Im in the process of installing these rods and they are giving me a hard time. I bought them used from a guy that had them on his 99 SRX. Is there drilling required? The rods are almost 2" longer than stock when held next to each other. They will bolt up but they is no play in the suspension. I can jump up and down on the back of the sled and it still probably wouldnt move. Theres not to many possibilites. Its either there the wrong rods he sold me or i have to drill. Any suggestions. He told me they are the TC3's.
