I do the work for you and figure out what belt you’ll need if you’ve got a 2016 Jeep JKU with a Ripp Supercharger with high altitude pulley and the PSC power steering pump with the larger than stock pulley.
The verdict is 89.75” length (2278mm x 20mm).
The 90” belt that PSC supplied may be good with the standard Ripp pulley (unverified). With the high altitude upgrade there’s just not enough tension lock to lock.
