I have a Hellwig front swaybar on my '23 XLT, and am looking to add one to the rear. Hellwig lists a different part number for 21-23 vs 15-20 with a significant price difference. Additionally the kit for lifted trucks is CHEAPER than the kit for stock ride height....so I am trying to find out:
1 - what is (if any) the difference between 15-20 and 21-23 rear suspension
2 - what are the functional differences between Hellwig p# 7743 (15-20) and p# 7788 (21-23)

Thanks!

 

I don’t know the answer but the hellwig rear sway bar was probably the best mod I did to my truck besides maybe the intercooler upgrade.

 

I would buy it today if the pricing wasnt so weird:
lifted kit is $685 -- kit for stock truck is $985 -- previous year kit I can get for $588

 

Holy poop! I had a small stroke paying like $425 for mine.

AFAIK the lifted kit just has longer links.
