Re: Stiffer ride for the WJ?
Shocks go a long way, I too would recommend Bilstein.
Beyond that, I'd look into at minimum a used set of low mileage coils (preferably Upcountry), if not a combination of Eibach springs + coil spacers to bring the height back to factory levels so as to not upset the drivetrain/suspension geometry.
Due to my workload, please do not PM me as I do not regularly check my PMs. Thank you :)
