Hi John,
KingPins were done last year and showed no wear when removed. The OE front springs on my 2014 4/4 were under strength and the front end crashed over bumps. I hope the SSL kit will solve this once and for all without making the ride too stiff.
I have replaced all 4 shocks with the SPAX that are recommended alongside the SSL kit.
Test drive is tomorrow's job - ran out of time today with other pressing matters - including feeding our horses.
