    Suburban tire thread (help needed)

    Howdy gents, Tomorrow I put some new tires on Tina our C20 454 2wd suburban. I’m leaning towards 2 options (getting rid of the 113 flexy pirellis on it). 1. Nitto 420 staggered setup -Rear 305-40-20 F Ply 122 load 3307lbs per tire (80 psi max) - Front 275-55-20 XL 117 load 2833 lbs per tire...

    Twitchy steering with a big travel trailer (rear sway bar help?)

    Thanks. I was trying to get the look of these tires while getting at least 10 or 12 ply load ratings on the rear axle. The tires pictured above are too wide for the front 305-50-20 but will work with the rear (and look badass). But I will need to get then 275-50-20 for the front in the same tire...

    I test fit some 12 ply tires today. What are y’all’s thoughts on 12 ply rear tires and xl front? Thinking of a staggered fitment for these tires for the hot rod farm truck look lol:

    Thanks. The other i encountered was that 3 out of 4 tows have been in 20-40 mph winds. I know that has a lot to do with it as well.

    Twitchy steering with a big travel trailer (rear sway bar help?)

    With the shackle drop on the rear springs, this rear end squats like crazy with the trailer attached. Without the airbags aired up, the tongue weight drops 100 pounds. Once the bags are aired north of 50 psi and the weight distribution hitch is setup, it’s displaying 3k worth of weight tension...

    Do you think a rear sway bar does any good in my setup in addition to the e rated tires?

    Twitchy steering with a big travel trailer (rear sway bar help?)

    Driving it home tonight even without a trailer I can feel the light twitch in the steering. It’s almost like it tracks and darts quickly from one side to another in a short amount of steering wheel turn but drives straight down the road. Maybe I need to look at my alignment.

    Trailer only. This truck weighs around 4600

    Twitchy steering with a big travel trailer (rear sway bar help?)

    Thanks for the response. The empty weight on the trailer at the scales was around 8600. Im assuming that we probably add 1000 pounds once loaded but I need to verify this. Typically my tounge weight measures in between 875-950 pounds based on the tongue weight scale I have. Once this is set, I...

    Twitchy steering with a big travel trailer (rear sway bar help?)

    thanks! I have a weigh safe heavy duty distribution hitch that helps me dial in perfectly by weight. The squat is good with the rear air lift air bag system at 65 psi. I’m running some pirelli scorpions at 45 psi (Max 50).

    Twitchy steering with a big travel trailer (rear sway bar help?)

    Howdy all, My 85 suburban has a 2” static drop (shackles rear, coils front). We replaced all steering and suspension components up front, new control arms, tie rod ends, borgeson quick ratio box, etc). We installed helper air bags for the rear when towing and it helped tremendously but when I...

    New steering pump and still leaks power steering fluid. Do I need a different pump or Lucas stop leak?

    Is there any detriment to the stop leak Lucas?

    Dried it off but after a bit of driving it looks like it comes out of the cap.

    New steering pump and still leaks power steering fluid. Do I need a different pump or Lucas stop leak?

    Howdy all, My power steering on this truck has been the bane of my existence. The pump is a new lares 12348 and I have custom high pressure lines made because my newly purchased high pressure lines kept splitting. We also have a Borgeson tight gear ratio box. My issue is that it leaks like...
