installed the 5100 in the front and the new h1s in the rear .the h1s replaced the h5s . h5s I believed are not made anymore .what a ride ,smooth ,and very stable ,corners better.love the shocks .just wanted to let everbody know

 

I have never used a better shock, Billys are worth every penny IMO

 

hey kully560, when I ordered my new 5100s I noticed the rears are now H1 ... changed from H5. The fronts were still H5. I asked what the H1 meant and was told that they just changed the part# ... that's all. Do u know what the difference is with the H1? They are still zinc plated like the H5 right?
btw, congrats ... good to hear you're happy! can't wait to get mine installed finally ... just gotta go pick 'em up.

 

For you alll running billies, is the height of your truck stock? I was told by them they do not make a shock for our trucks that are stock height.

 

I have the 5100s all around and honestly can't tell a difference from the stock ones... Oh well, they look better.....
