Do I need to simply live with it, or will a rear sway bar help? | | | | | Joined: Feb 2023 Posts: 374 'Bolter | | 'Bolter Joined: Feb 2023 Posts: 374 | I put one on my 66 C10. It’s been 50 yrs since I last drove a 64/66 C10, so I don’t know if it helps or not. I figured it can’t hurt & might help. FYI, it wasn’t expensive & was easy to install. | | | | | Joined: Oct 2021 Posts: 6,698 'Bolter | | 'Bolter Joined: Oct 2021 Posts: 6,698 | It's a 60 year old truck. You also aren't taking into consideration that you are using radial tires. Bias ply tires that the truck was designed to use have extremely stiff sidewalls that prevent a lot of body roll. Bias ply tires make a car ride like it's on rails.
Radials have more flexible sidewalls allowing the tread to grip the road in turns and curves instead of skidding along the surface.

I ask because on my 46 I have Diamondback Auburn “pie crust” radials, the 1-1/4” tubular bar made a HUGE difference, I will say the rest of my suspension is original in style but all new(46 is ‘I’ beam front) Rear sway bar won’t do much to help unless you have a load, the springs out back are pretty stiff and there is no weight to compress them.

I think it was 1 inch I put on the front. | | | | | Joined: Sep 2020 Posts: 438 'Bolter | | 'Bolter Joined: Sep 2020 Posts: 438 | I’ll be the first to say I don’t know how to calc what sway bar is needed, every little thing affects function (like links, mounts, rubber, poly, heims) it also helps if all the suspension is in top shape. On the race cars it was try a few, especially on the rear…and those were adjustable.

I had some horrible Coker radials on that felt like it was going to fall over on a cloverleaf exit ramp. When I switched to Diamondbacks, the roll went away. Bias Plies were even better.

The wife & I put about 120 miles on the 66 last weekend. I paid attention to the sway or roll while cornering and there wasn’t any . I think you’ll be pleased with the results if you install a rear sway bar. I think mine are 1 1/8 front & rear. I’ve also got BBC coils in the front & new std’s in the rear. | | | | | Joined: Nov 2021 Posts: 1,258 'Bolter | | 'Bolter Joined: Nov 2021 Posts: 1,258 | RLB. A rear sway is on my amazon list for x mas. | | | | | Joined: Jul 2021 Posts: 213 'Bolter | | 'Bolter Joined: Jul 2021 Posts: 213 | My experience in the past with different truck sway bars has been beefing up the front where the majority of the weight is makes a world of difference. Not a lot of weight in the rear that gets slung around, unless you haul alot of cargo. On one truck I replaced the stock .75" front to a 1.125" and installed a .75" rear that had none before. Looking to rally race it. It rode horribly. Removed the the rear and it drives 140% better than before the front swap out. Pretty much most of the modern sway bars have little sway links on the sway bars in the rear, so adapting any sway bar on an older truck is going to be trial and error. I will find out this summer when I get my '51 3100 with C4 Flat Out Engeneering suspension with an upgraded larger C5 front bar how it handles on the road. I might be adding a rear bar.
