Outer Limits 4x4 Board

Procomp shock lengths. Change part number first digit to 9 for ES9000 series. 'xx' is for different mounting types, eg pin, eye etc. (talk to your dealer). My understanding is that the ES3000 series have softer valving but ES9000 more suited to heavier vehicles. 3275/3295 look good for 4-6" lift GQ rear.
Sorry table is a bit hard to read, cut and paste from Excel.

Any idea where these are measured from?

ie In a pin-pin config on the front of a Patrol, is it measured pin seat to pin seat, or half way up the pin or top of the pin to top of pin?

(I know the standard is pin seat to pin seat but sometimes it is measured differently)

Most shock places seem to measure from eye centre to eye centre..... or if it's a stud (or stem) type end to the end of the polished shaft (ie. not including the part the rubber bushes sit on.)

Hopefully that makes sense?

This is how I've always measured shocks. Am just wondering if all manufacturers specify using the same measuring points.
