As with every order to my friends at James Duff, this was no exception. I added these shocks to by 76 Bronco crawler build this week. I have run them on my street bronco for years and they are great shocks. I expect these to work well in this application too.

I was unsure I had picked out the correct shock for my application and made a call to to them. They took the time to make sure I had proper measurements to get the correct shock. Great customer service and knowledge I’m very pleased with the james duff staff and highly recommended to everyone.

Great product fit perfectly for what I was looking for. Good length and a rather impressive looking shock as well. Everything seems to be workin as it should.

I’m very pleased with the 8114 shocks, they perform amazingly on and off road!!! I tested them hard and they performed perfectly and are working perfectly. I really recommend James Duff parts.

went From eight 8110’s to eight 8115’s on all four corners after them being recommended based on my measurements. They fit perfectly and handled great when testing hard. The best shocks for the money with out a doubt and correct valving for my 8 shock set up. Stayed with The 70/30 shocks since my last set lasted for 22+ years.

i just replaced my Duff 70/30 shock which i purchased in 1997 with new Duff 70/30 shocks they have held up great and this is why I repurchased the same shocks. The ride is great with the old and even better with the new ones
