Shocks

Recommended Posts

I'm bouncing all over the road!  Especially when towing 10k 5th wheel.  What shocks do you recommend and where to purchase? Thx!

I want to try kyb mono max per another forum. Have yellow bodied bilsteins on it now and they suck with the current tires.

I have ran many different shocks over the years and what I have learned is that I'll never again touch a Rancho shock but I will continue to buy Bilstiens. 

 

I have the 5100's on my truck right now and they are by far the best shock I have ever ran.

Personally, I think there is way too much hype for Bilstein shocks.

 

I have to agree.  Any vehicle I've driven/rode in that has Bilstein shocks had a very firm/hard ride.  Bilstein shock may be good for the track but not the road.

After 93k miles and only paved roads I still have the original shocks on the my truck but the shocks or struts I put on customers' cars are the Monroe Sensa-Trac.  They are a gas filled shock that gives a nice ride, are reasonably priced and never had one fail.  They are available for the Ram 2500.

I have 4600s on the 24v that I bought new. Zero complaints with the two different sets of tires. Now the 4600s on the 12v....good god they are bad.

I don't know how you guys tell the difference in how ruff the truck rides, mine rides like a brick unless it's loaded. Original shocks were still good but rusty with 150k, but when changing front Springs I stripped both top front threads, so I cut them off and got bilstin 5100 and they were on sale for 35 a piece  I think or even cheaper. They are a single wall thats thicker and have larger piston, so that's my story.

Are you sure it isn't the new front springs?

 

5100's firmed up my ride over OEM shocks but in a good way. The OEM's were spongy and the 5100's are crisp and it now handles the way it should empty or loaded.

Yeah its been this way forever,  when I bought it before bumbers or springs or shocks. Noticed it right away but knew it is what it is. I know that my work truck f350 rides better. I'm ok I still like the bitc..

Most likely the tire pressures are too high. This one reason I run two different tire pressures because if I left the tires inflated for towing then the ride is really harsh when I'm not towing.

What is a good money saving shock for a work truck? Is Monroe any good to save bucks with?

I have a set of Monro-matics on mine from rock auto. $20 apiece. They keep the wheels planted as they should but the ride is firm. Pretty much like mine was stock. I had been running my tires around 55 in the front and 50 in the rear. Just got the tires rotated and balance and I am sitting a 65 all around at the moment. I did not notice much difference in the ride coming back to Maryland.

I have my tires set to 50psi. Tire shops keep putting them to 70-80psi. Noticeable difference between there. I may drop tire pressure lower to try and help. I just dd this and not much towing.

The tire shop put my rears at 80 during the rotation, fronts at 65. Decided just to try 65 all around. 80 in the rear with no load equals no fun. Probably going to air them down some anyway.

Empty tire pressures for my truck are...

  • 60 PSI Front 
  • 40 PSI Rear

Now what will it carry???

  • 60 / 80 = 0.75 x 3042 = 2281 x 2 = 4563 pounds on the front axle
  • 40 / 80 = 0.5 x 3042 =1521 x 2 = 3042 pounds on the rear axle
  • 7605 pounds carry weight

My truck actually scales at about 7,400 pounds with Mom, Diesel and myself in the truck. 

 

Trailer towing

  • 60 PSI Front
  • 60 PSI Rear

Now what will it carry???

  • 60 / 80 = 0.75 x 3042 = 2281 x 2 = 4563 pounds on the front and rear axle
  • 9126 pounds carry weight (Remember the truck is rated for 8,800 GVWR)

5200 + 6084 = 11,284 pounds carry capacity. I hardly doubt your anywhere near that empty. Even doubtful with your RV. I know it big and heavy but 2,484 over GVWR...

I am running around 7800 right now. Got to empty the back seat for the current job. The rear is a little stiff with 65 but the front likes the 65. I do pump them up for towing though.

Just for fun comparing...

35 PSI 1700# = 1700 / 3042 = 0.55 x 80 = 44 PSI 

40 PSI 1870# = 1870 / 3042 = 0.61 x 80 = 49 PSI

45 PSI 2030# = 2030 / 3042 = 0.66 x 80 = 53 PSI

50 PSI 2205# = 2205 / 3042 = 0.72 x 80 = 57 PSI

55 PSI 2335# = 2335 / 3042 = 0.76 x 80 = 61 PSI

60 PSI 2485# = 2485 / 3042 = 0.81 x 80 = 65 PSI

65 PSI 2623# = 2623 / 3042 = 0.86 x 80 = 68 PSI

70 PSI 2765# = 2765 / 3042 = 0.90 x 80 = 72 PSI

75 PSI 2905# = 2905 / 3042 = 0.95 x 80 = 76 PSI

80 PSI 3042# = 3042 / 3042 = 1.0 x 80 = 80 PSI

 

I think I'll keep my math thank you... 9 PSI drop at the low side of the scale is rather way too soft for the amount of weight.

Not all table are created equal... This Michelin weight to pressure table. Same sized tire and capacity...

569423d53a27f_tirepressures.png.da24cfce

 

35 = 45 PSI (10 PSI different with Michelin)

40 = 48 PSI

45 = 52 PSI

50 = 57 PSI

55 = 60 PSI

60 = 63 PSI

65 = 68 PSI

70 = 72 PSI

75 = 76 PSI

 

Still in all this would with either table have my rear axle pressure below the 35 PSI because tire weight is only 1430 pounds (Axle weight 2860 / 2). So would a person gamble with 30 PSI at 1,430# ???

 

1430# / 3042 = 0.47 x 80 = 37 PSI (Currently set to 40)

I've ran mine as low as 35 on the rear, table weight,  and they wear great, have great traction, and don't get hot. 

 

XPS Ribs have a steel sidewalk and likely the reason for slight differences. They will also have a higher minimum pressure, thou neither table goes that low.
