Could anyone please help with this problem? I have a hannigan astro g.t. and would like to know if anyone has the shock n umber from progressive or has upgraded their suspension as the stocker is weak. Please let me know as my email and phone call to Hannigan did not yeild anyn results. Help woud be greatly appreciated by us all we love our rig and have had it for about five years Peter,Deb, and the dogs Thankyou in advance
I upgraded the spring from a 120/170 to a 150/300 and it made a huge difference. Got the spring from hannigan for about $35. Unless your shock is leakingmay not need shock. Have bought several shocks from progressive by length and attachment (clevis, eyelet). If you contact them direct and tell them you want a single shock for a sidecar they will make arrangements as they advertise as sidecar suspension specialists.
