I didn’t realize shopping for shocks was so complicated.

[HTC42]

I’ve been on the internet (I know, it’s dangerous) but geez. I gotta give you my credit score to figure out how long of shocks I need? Im fooling, but the search refines are weird. I’m looking for the zen of bilstein in a condensed version.

Thread 'FJ40 Shock Absorber Options - Compressed and Extended Length Data'

May 29, 2020
