Dobinson Shocks with OME Springd (1 Viewer)

[rexlap]

99 Landcruiser. Previous owner had installed OME lift and springs. Just replaced with Dobinson springs (yellow) and kept the same springs. Also replaced sway bar control end links, front UCA and ball joints on lowers. Tires are 265 Geolanders. I’m planning on adding some Toyo AT3s, but concerned heavier tire will make ride worse.

The ride is super harsh. The thrashed old OME springs almost rode better. I can feel every bump on the road and even the painted over crosswalk can be felt.

I have ARB front bumper, but wondering if the OME spring is causing the harsh ride? Anyone run this setup and have advice?

I’ve read that adding weight can help, but haven’t thrown any weight in the rear to test out. Hearing more rattles on interior after having all this work done.

Not clear to me what you replaced: shocks or springs? I assume you left the OME springs, but replaced the shock with Dobinson?
And I assume you have a stock vehicle without a different bumper and so on on the rear?

Can you specify the part number?

sway bar bushings, UCA and ball joint should not make you ride so much different (beside the sway bar bushings were really dead...).
So there's a chance that the shocks are just not made for your weight OR your shocks before were shot and therefore didn't dampen anything. And now you're missing the wavy feeling

Thanks for reply. Replaced shocks with Dobinson GS59-782 and GS59-682 I believe. Yellow shocks. Rear bumper is stock, front is ARB. Previous OME shocks felt stiff as well.

I left the OME springs in there. Need to look if they are heavy duty or standard. I assume heavy duty will lead to feeling stiffer?

62 owner, but did something close to what you did.

OME shocks were worn out. Running OME heavies (springs front and rear… winch, Trail Tailor front bumper and Dobinsons swing out in the rear).

Pulled the OME shocks and replaced with Dobinsons IFS shocks…. HUGE improvement both on and off road.

First thing to check is “how much droop do you have in front?”. Insufficient front droop make just about any spring/torsion bar/shock combination ride like

Great thought. Thank you! Just went out and checked. I have a 10mm drop from rear to front.

Based on other forum posts, recommended is 50-70mm.

Will I need an alignment after adjusting torsion bar?

By front droop, I’m referring to the measurement from the center of hub to fender with a tire off the ground, minus the measurement from center of hub to fender at rest (tire on the ground).

yes, you'll need an alignment once you play with the torsion bar and move it up/ down.

Measured this past weekend. 40mm droop for the front. Attempted to loosen torsion bolts and they wouldn’t budge. Dang rust trucks Soaked in PB blaster. Will try heat and a cheater breaker bar.

Also looked at rear control arm bushings. They are showing wear and cracks. Wonder if that would play into harsh feeling as well?

100 series aftermarket suspension manufacturers recommend anywhere from 50-70mm as minimum front droop.
