Where are you getting that info? I havent seen anything on any of the toyota oem parts websites stating whether or not any of these coils are fixed rate or progressive. On this website some of the coils listed say they are for the "off road package", and others are not. I assumed that the "off road package" coils are progressive while the other are fixed rate. However, I dont know for certain again as they dont state it anywhere.
We have to get to the bottom of this! Need progressive coils!
Unfortunately the only specs I found were for aftermarket,not OEM. I searched Rock Auto (entered 2003 Tacoma) and found Moog # 81104 and AC Delco # 45H0376. Moog's are 595 lbs/inch fixed rate,no specs on AC Delco but the picture shows the same spacing between each coil except for the very last one http://images.wrenchead.com/smartpages/partinfo_resize/DCL/45H0376_Primary.jpg so I'm going to assume they're fixed rate.
