4" FT rear Coil Springs installed
After installing the 3” Full Traction lift w/ HD front coils on a 2 door rubicon I noticed that my tail was slightly lower than the front end. My tail drag was even more noticeable when I loaded up the jeep for camping trips. This wasn’t a driveability issue, but it still bugged me. I discussed this with several people and came up with the following solutions.
1. Install rear spacers - Cheap, would level out the unloaded vehicle height and wouldn’t change the ride quality (ie. Spring rate). Wouldn’t allow for height adjustment when the jeep is loaded. http://northridge4x4.com/proddetail....d=TF-001954100
2. Install air springs - Inexpensive, gives me the ability to set ride height with the jeep loaded or unloaded. I don’t know that they would change the spring rates, but I think that they would. They would need regular checking to ensure
that air pressure is maintained. I may still do this. Full Tractions new springs (3 & 4”) are now trapered. The springs would have to be measured and compared to air spring specs. In order to find the correct application. http://project-jk.com/jeep-jk-write-...ation-write-up Way-of-life has a great write up of this install.
3. Install adjustable rear spacers - Pricey, but would definitely work and would allow me to adjust ride height for camping trips. Doesn’t effect spring rates. http://northridge4x4.com/proddetail.php?prod=JKS-2570
4. Shorten the 3” HD front springs by cutting them to a shorter length. - No $ cost, just labor. Would level out the jeep, but with a slightly higher spring rate in the front. Tail would still drag when loaded for camping.
5. Install Full Tractions new 4” rear coils. - This is the option that I choose. Available now from Full Traction. They charged me $200.00. Installation was very easy, I used Way-of-Life’s 3” FT installation write-up. Installation took only 2 hours. Installation leveled the jeep and provides a slightly higher spring rate for when I am fully loaded. http://full-traction.com/
3" Lift Loaded in Death Valley, but with gas cans empty
Jeep unloaded w/ 3" Ultimate Lift. 3" HD front springs and 4" rears.
