Dobinsons 5th Gen T4R Suspension options - from Exit Offroad

[ncflyer]

Mike,
Decided to reinstall ICON 2.5 ext. travel (extra 7/8") from a previous vehicle on current 19 4runner. vs long travel option I PMd you about.

I will use ICON 650Lb spring that came on the coilovers with app. 220lbs constant on the front. RTT and sliders more centered...280lb and the rest more over rear axle with drawers and extras, about 300lbs. I looked at your information on coils and thinking the 327 or 329 if they would work with the ext. travel set-up or if better the 675or 677V.

Weight may vary up or down as I use vehicle and would like not to have rear to rough with weight reduced.


Thanks for any information

So which rear shocks will you be using? I'm not following, as I think the 2.5's are only up front but they use a 2.0 in the rear maybe? Doesn't really matter, I'd just need to know the fully extended length of them to let you know if the 327's or 329's would work with them or not.

The Dobinsons LT rear shocks would have the 327/329 coils fall out at full extension, but they're also super long.

I think the 327's would work fine for you based on the weight you're carrying for 2" of lift, or the 677V's for 3" of lift.

The rear is 2.5 with adjustable res. as well.

The piston length from the bottom of the shock to center of lower mount hole is 10 and 5/8". The full shock measured from the lower mount center to top of shock not including rubber bushings is 24" so about 25 1/2 to center of rear top mount. As measured off the vehicle so would assume they are at full extension. The 2" springs that came with them measure right at 16 3/4 ".

OK, cool. Those won't be a problem to run with any of the coil options. They're only a fraction longer than the 701 shocks from Dobinsons. The LT's are 28.75" fully extended.

Great. Thanks Mike. Just gotta decide how high I want the rear. Thinking long travel 675V or 677V since they are variable when lighter weight is in the rear. Shouldn't be as harsh a ride when lighter correct?

Correct, the 675V and 677V are both lighter than the 327's even when fully loaded.

Been all over this forum since I got my 2020 SR5. The picture attached shows what I end up with. Now my question and concern is about the front GS59-574 extended shocks... would that make the ride quality a little more harsh?? This truck is my daily and unfortunately living in Florida I can't really offroad much if at all . I mainly got the vehicle for road trips a couple times a year and getting it in a trail here and there if I get the opportunity. Because of that I want to keep it as conformable as possible for my daily commute. The reason I end up with that setup is because it gives me the exact ride high I'm looking for and in reality I don't plan on adding any permanent heavy equipment for the time being.

Harshness will come from the stock UCA's not having a lot of travel left in them when it's lifted close to 3" up front with that combination. You'll want to look at upgrading those at some point to help with that and also to get your alignment caster into spec as well.

Mike - Getting ready to place my order with you.
2019 Off Road with KDSS

Will the IMS have black or that Australian purple color adjustment rings?

Wanting to keep the factory rake but would maybe like it not as much of a rake as it is now as factory. It's factory no additional weight now or planned.

C59-302 Front with C59-325 in the Rear....Does that sound about right?

So is it true Red and Black coils are the only colors available?

Black adjuster rings.

302 front and 325 rear would be 2.5" front and 2" rear, 1/2" less rake than stock.

Red and black coils for the front are what's due by the end of the month, 325 rear coils we don't have an ETA on yet. End of December or sometime in January.

When they make different color coil runs, they have to do as many at one time as possible, so some containers have all one color, or sometimes mixed, but rarely all 3 colors.

You can also order whatever colors you want and just be prepared to wait for them to arrive. No later than January everything will be in stock for orders placed this month, I'm predicting.

Mike- 302 Front 2.5" with a 505 Rear 1.5" Is this what people get for it to sit level?
I'm probably going to wait for the 325's to come in but I will order today anyway.
You would just ship my order when you have everything.

2.5" front and 1.5" rear has it sit with 1" of rake. It's super common. It looks a lot more level than stock at that point (1" of rake), but the bodylines of the whole vehicle slope forward, so it's always going to look like it's leaning forward when viewed from the side.

In this photo the black truck has 302 front coils and 725 rear coils (325 coils with a built in 15mm offset for KDSS lean). The white truck has 302 front coils and 505 rear coils.

Thank you for the info Mike I'll definitely be upgrading the UCA. I hope this setup would get me close to even. I was going to go with the Eibach pro truck lift because how even it looks with 2.8" F n 1" R. I figure this setup with 2.8 F n 1.5 R would get me close to that.

Hey Mike, i placed an order for a set of teal c59-505s at the ned of october. Are they still slated to arrive mid this month? thanks

More like the end of the month now. Those hurricanes slowed down the ships again and backed up the ports.

When will MRA59-A575s be back available?

 

[Crikeymike]

When will MRA59-A575s be back available?

January sometime most likely. We can see everything that's coming before the end of the year, and they're not in any of the containers.

Black Friday pricing applies to all backorders too, so you can place it with the discounted price and we will still ship it when they arrive.

Hey Mike,
I'm want make sure I'm ordering the correct components. I'm looking for a 2.75"/2" lift. I usually run around with minimal weight except for occasionally camping/overlanding trips (4 times a year). Is this correct for what I'm looking for?

Front: C59-300 (red) + GS59-574 (black)
Rear: C59-325(red) + GS59-705 (black)
Dobinson UCA + Diff Drop

Also, are the Extended Rear Swaybar End Link Kit recommended with this suspension setup even though the GS59-705 are not the long travel?

Thanks!

Super helpful thanks OP
