Yes you can have a shock absorber optioned in from the manufacturer. I would contact Kris Granning owner of G-Tech in Detroit Mi. at 1-800-322-4832. They are super helpful and won't sell you a bargain you can't live with. These folks know what there doing and are professional all the way. Good luck and keep us posted how it goes. FYI, tag axles are only accepted and legal for use in Canada with shock absorbers!
