Best money spent
Well worth the money. Replaced original shocks 1980 KZ 550C LTD with a less expensive brand, my 3/4 ton truck rode better. With the Progressive Suspension 412 series standard duty now have the ride I wanted. Should have just bought these instead of and would have saved $120.00. Fit was right on especially liked the steel bushings and offset eyes. Nice looking shock, keeps the retro look. Highly recommend for vintage bikes. Dennis Kirk as usual is easy to deal with. Called in for advise and was right on. Thanks
