Dobinsons 5th Gen 4Runner Suspension options

@Crikeymike
Hey mike, had a quick question on rear spring recommendations. wondering what your thoughts are between these 3 options (or a different brand/model like the Icon Overland or OME 889) for my setup

• C59-327 - 200-400LB heavy rear load weight, 2" lift. 410/410mm, 18mm wire, 271LB
• C59-675V - Variable rate comfort option, stock rear weight, 2.5" lift. 470/470mm, 16mm wire, 157-230LB variable
• C59-677V - Variable rate comfort option, 200-400+LB heavy rear load weight, 2.5-3" lift. 500/500mm, 16mm wire, 157-230LB variable

Currently running Toytec Superflex HD 2" rear springs (150-200lbs added weight)


I have about 150lbs constant weight in the back of the truck between the fridge, drawers, and gear. however, I have a rig'd ultra swing I take on and off that adds an additional 200lbs or so which is why im leaning toward a variable rate. Are the Dob 6xx series strictly meant for long travel shocks and would the 677V be too harsh without UltraSwing on the vehicle? id like to not be under 2" when fully loaded (350-400lbs) but under 3" when unloaded (150lbs)

 

Hey bud

From what I've seen, the Toytec coils you have now are very similar to the 677V's, just not as tall. So if you purely want more lift height, use the 677V's. The 675V's will be softer and probably won't support it very well with the fully loaded weight. The 327's would be ideal as far as spring rate and the load you'll have, as long as you want 2" of lift.

No, LT coils don't require LT shocks, but to run LT shocks, you must run LT coils and all the other parts necessary for the LT shocks.

So the short answer is use C59-327 for 2" of lift, C59-677V for 3" of lift. 677V's will sit taller without the 200-400lbs of load on them that is listed. Any coil will do that, if you don't add the weight that's listed with it, it won't sit at that height.

 

Gang,

Anybody here have before and after pictures on the C59-327 Coil Springs? These are the 2" - 200-400LB heavy rear load weight. I'm coming off a 2" Icon and wanting to see how the back looks. Thank you!
