Hmm perhaps the lift is less than it looks.
I have the Moog 81117 on the rear, they are listed by most ( but not all) websites as fitment for the R51 4x4 V8.ShipFixer wrote: ↑Mon Apr 26, 2021 1:34 amThe Moog 81119 (4WD rear) springs are 353 lbs/inch, and the 81280 (4WD front) springs are 450 lbs/inch. Moog lists the 81280's as replacements for all three truck types in 4WD varieties.
All of the lift springs I can find start around 480 lbs/inch and work their way up. There's a ton of conjecture on the Frontier and Xterra websites as to what the stock spring rates are...most of them seem to believe it's either 500 lbs/inch or 480 lbs/inch. But none of them can be correct looking at all of the listed spring rates I can findIf I still had the stock ones I could take some calipers to them and calculate the spring rate but they are loooooong gone!
The front was a tiny bit firmer and a little higher on mine, but not much. I suspect the stock springs are indeed around 450 front. Rear OEM are clearly less than Moog's 353 lbs/inch.
For clarity, Do you have the Moog 81117 on the rear of a V6 Pathy, or a V8 Pathy? I see both in your signature. I have been trying to figure out if the Moog replacement V8 Pathy rear springs can be used on the V6, and if they would provide more lift than the Moog 81119 that I currently have installed.palmerwmd wrote: ↑Mon Apr 26, 2021 8:40 amI have the Moog 81117 on the rear, they are listed by most ( but not all) websites as fitment for the R51 4x4 V8.ShipFixer wrote: ↑Mon Apr 26, 2021 1:34 amThe Moog 81119 (4WD rear) springs are 353 lbs/inch, and the 81280 (4WD front) springs are 450 lbs/inch.

The V8 r51 despite being heavier than the V6 truck is listed by Nissan as having a higher payload so I expect them to be stiffer Moogs.
On the fronts have the Moog ST8615 assemblies (strut plus spring)
