I've had a few people ask for access to my shock & spring charts, so I decided to put all this in a sharable format that anyone can access or download & modify. There's more than one tab at the bottom, feel free to view or download.

Shock Matrix
The following fields highlighted in yellow are adjustable.
  • The 'Ride Height' field uses my JLR as a base, but your Jeep may ride differently. Be sure to check the shock eye-to-eye measurements for accuracy.
  • 'Bump Travel' (or Up Travel) just turns some of the text red that is outside of the recommended range

OEM Springs: a never complete list of all the spring combinations

Rear Motion Ratio: shows how the rear shock's response isn't linear to suspension travel, and most important at lower ride heights

Spring Rates: a small list of spring rates I have collected from this forum

Caster: another small list, this time of caster measurements using fixed arms

Wheelbase: comparing the JL to other Jeeps

Breakover: how the JL & JT breakover angles change at various heights

Amazing work.
How do I contribute to the OEM shocks spreadsheet? I don’t see a JLUR with 3.6 and auto trans and all sections being True.

Small update comparing the OEM scrub radius variations, and what effect tire size has.

This is by no means a recommendation of what works or drives well, but it could help in certain scenarios. For example: a 37" tire on OEM JL wheels should use an 11mm-19mm spacer if they want to get back to OEM scrub radius levels.
