View Full Version : Rear suspension

01-15-2013, 05:28 PM
I have a 2004 Model 2500 long & tall. It is usually loaded almost to the max. Whenever I go over a bump or back out of a driveway the whole rear end jumps and wobbles. Quite often it bounces the stuff inside all over. I do not have any issues with it wandering around the road. I have read about several fixes and decided to try one or more.

In what order do you suggest I do them? The budget is a bit tight right now so I would like to do them in an order that would give me the biggest bang for the buck.

1. Change rear shocks to Koni Red's (part # 82-2434)
2. Rear springs
3 Rear anti-sway bar
What are your opinions?

Thanks in advance.

I have the same conditions only when lightly loaded, when full it's very smooth .
Lowering the PSI in the rear tires will help, but the springs are too stiff.
Just my humble opinion the best would be to replace the rear leaf springs with passenger multi-leaf springs which are weight adjusting to stiffness. I don't know the cost or if it's applicable to your situation.

Be nice to hear from someone who has replaced their rear springs with the passenger leaf springs regarding procedure and cost.
And of course.......which vehicle.

I installed this 4 years ago works great

I voiced this complaint to Andy when I was in PA. This was when Frito was brand new. He said that he'd replaced the rear leaf springs for several cargo T1N owners with passenger leaf springs as nelsonsprinter suggests.

Start by replacing the rear shocks and go from there. We have them in stock and ready to ship. Hope this helps.

Replacement shocks start at $40 each and take 15 minutes to replace. When my rear started bouncing, I bought a set of Bilsteins. People will tell you to get koni's for $200 each. I don't know if they are worth $150 more each.

Sounds like new shocks to me. If you have the cash, the Konis are sweet. If not, you can go stock or Bilsteins = best bang for the buck as surlyoldbill said.

$116/each here:

The Bilstein HDs are on sale for $91 each:

Standard Bilsteins can be found for about $60 each
