Just a quick heads up.
I received the Dynatrac Endurosport lift a few days ago and installed the front lower shock bolts with 80 ft/lbs torque as specified in the written instructions, step 12. Turns out that is too much torque for the bottom crush sleeves in the Fox shocks. The sleeves were distorted and the brackets bent way in and even the bolt was bent. Here's a pic:
I did not want to run my new lift with mangled parts so I contacted Dynatrac; they were very responsive and immediately contacted Fox on my behalf. Fox agreed to send me new sleeves and I received them today along with a nice new Fox hat. Many thanks to Dynatrac and Fox for taking care of me.
As I was re-reading Dynatrac's instructions for the 10th time today, I noticed that they have a section labeled Torque Specs on the last page, never noticed that before! On that page the recommended torque setting for the Fox shock bolts, upper and lower is 65 ft/lbs, not 80! Don't know how I missed that.... but for anybody installing the Dynatrac lift take note that 80 ft/lbs is definitely too high for the lower shock bolts. So even though the main instructions mention 80 ft/lbs, be sure to follow the Specs on the last page which recommend 65 ft/lbs.
I will be installing the shocks again tomorrow after I press the new sleeves into the rubber bushings. I am going to start the torque on the lower bolts at 50 ft/lbs and work up 5 ft/lbs at a time to 65, watching carefully to be sure I am not deforming the crush sleeves.
On that first day, I also torqued the top shock bolts to 80 ft/lbs and that was no problem, the Fox crush sleeves on the upper mount are strong enough to handle the higher torque. When I reinstall the shocks I am going to use 65 ft/lbs on the upper bolts as well.
I should also point out that the Jeep factory spec for the lower shock mount is 74 ft/lbs which I believe is also too high for the Fox shocks. Here is a pic showing why - the factory torque spec is based on the factory shocks but the crush sleeves in the factory shocks are much thicker, beefier than the Fox crush sleeves.
I am sure the Fox shocks will work perfect now that I have new sleeves and the proper torque. Will be taking the Jeep to Discount Tire on Monday to have Cooper 37s and KMC wheels installed. Will post some pics when the tires are on.
