Ok, after multiple SNAFUs - one UPS' fault, the other the manufacturer's - I got my sway bars in today and installed this evening. It's this kit here:
https://www.nolathane.com/collections/all/products/rev013-0030-sway-bar-vehicle-kit I got the Spohn SEL-19-416 front and HELLWIG 7961 rear links because the OEMs are weak and were shot. The front bar is the largest you can get on these trucks - 38mm/1.5" solid - same as the Hellwig. The rear is 33mm/1.29" solid, 1mm larger than the Hellwig. The Hellwig front reuses stock end links, rear includes their rear links. I am confident that with the Spohn front links and the marginally thicker rear bar, I have the best setup available for these trucks. No downing Hellwig, it's clearly an awesome product but I saved ~$150 and still got stout front links and ever so slightly thicker rear bar. Even knowing what to expect (this is my fifth vehicle to upgrade sway bars), the improvement is DRAMATIC. Holy SHIT this thing turns and stays glass table flat. I've only done surface roads, no sweeping highway flyovers or U-turn exits...that will come. Even so, this is THE setup for these trucks IMHO. I've been left impressed with several vehicles with the magnaride shocks but I will take these all day long...especially if/when the time comes to replace them. Regardless, every car, truck and SUV should have monster anti-roll bars if you actually enjoy driving. The amount of confidence and comfort for both driver and passengers is noticeably improved over factory and it's 95% as cushy as stock just driving around. Even turning in the driveway is improved, it's that dramatic of an improvement with almost no downside. Supply chain ******** is still a thing and this is $1200 in parts but were I buying this truck new, I'd happily pay double that for this as a factory option. With this and the Hawk LTS brake pads, she is ready for 20s (has the 17s now) and a power upgrade. Absolutely transformed this truck from a comfy but wallowy pig to responsive, flat turning, great handling vehicle that to most people is still factory comfortable. It really has no business driving this well, but it does. Highly recommend Bilstein shocks and the biggest solid sway bars you can find!!
