SchrockWorks Bumper on Stock Suspension

Long story short, this is my parents vehicle that I am repairing for them. 2013 SR5 that was recently banged into a support beam and side of a brick home needs to have its front bumper fixed. Its actually cheaper to buy a replacement bumper due to the damage to the stock bumper. My parents live in a part of the country where the roads are questionable and because of this they prefer having a winch on their vehicles. The 4runner has yet to get one. So here is the question...Parents aren't wanting to lift this vehicle if they can help it...How bad is the stock front suspension going to sag with a Schrockworks bumper and Ramsey 9500 winch on the front?

If its going to be bad...is their a recommended way to level the front without installing a full lift kit front and rear?

Trying to help them make the best move and not drop more coin then they want to.

Thanks for the help ahead of time and for not flaming me...(I've wheeled a Jeep YJ for almost 15 years and don't know anything else)

Cheers!

A front bumper and winch probably weighs around 200lbs. Pop the hood and get a 200lbs guy to sit or put all his weight on the top cross beam to see how much it will sag.
 
I'm not advocating a better or worse case, but you may be looking at a several month wait for a Shrockworks bumper. Have you considered an ARB bumper? They are normally in stock and immediately shippable. Weight and general dimension should be the same The biggest difference between the 2 is the Shrockworks bumper sits back closer to the nose. As for the added weight on the nose, if your parents are unwilling to go with an aftermarket kit you should be able to find a spring maker who can make you a pair of custom front coils to adjust for the additional weight, for about the same price as a pair of regular coils. In fact with a little searching, if you cite an ARB front bumper I'm willing to bet there are shops out there who already have the specs on file.

I would recommend doing the adjustable Toytec Coilovers and just not lifting them. You need a stiffer spring and a better valved strut. You hit the brakes on that in a emergency and you could really hurt yourself or someone else because your vehicle was under sprung.

These trucks are slightly under sprung to begin with and after a couple months of driving you'll destroy the struts and springs doing that.

I'd rather fix it right and get a budbuilt plate w/ a synthetic lined winch and call it a day.

I ran stock suspension with a shrockworks bumper, lost less than 1/2" but it looks like a lot more since the lowest point in front becomes exposed. Lead time will be your biggest issue IMO. Really though by the time you pay for a new bumper and winch adding some front Bilsteins for leveling should inconsequential.

Also look at the budbuilt bumper. It's lighter, close to the same look and will be there faster.

This wouldn't give you any indication of how well the shocks and springs will resist compression and recover from compression with the extra weight while moving though. That's a lot more important than how much the front end sags at rest especially if you're driving down a potholed road and constantly hitting your bump stops.

How good would the winch be held down? What would his winch mount be bolted too?

I think the BB hidden winch mount is foot down. Not as good as foot forward, but unless they're gonna be doing some pretty serious winching it should be fine. Harper has the hidden mount and I know he's used it for real without any issues.
 
Recovery points on OEM bumpers, air bag triggers

or hook a tow strap between the front tie downs and have someone stand on that.

¿Are there tow hooks or recovery hooks on the 5th gen 4R Trail edition? I haven't seen any evidence of them in any of the photos, specs or literature. Recovery hooks are really useful for getting an assist or pulling others out as well as moving logs or big rocks (I've done this to clear a road). Having Shrockworks, BudBuild or ARB front bumper would provide these recovery points.

Does anyone know if the ARB or other rear bumpers reduce the overhang, increasing the Departure Angle for better clearance? The ARB also offers a rear spare tire rack. I see the tow bar slot in the photo too so it is compatible with towing a trailer.

Do these front bumpers require modification to the air bag sensors? Does anyone know how the sensors work in the front? Will having a much stiffer bumper reduce the trigger sensitivity for the air bags? Air bags are an important safety device for on-road travel. I wouldn't want to compromise their operation.

Any comments on these questions would be much appreciated. Thanks.

Um, your post is an entire thread on its own. All your questions have been answered on the forum if you look around, but I'd suggest posting a new thread.
 
Hijacked the thread?

Yea, it looks like I hijacked this thread to ask 3 more questions. But two of the points were raised here or in the links. Someone mentioned the tow hooks and I thought I saw a reference to the air bag sensors.
I added a question about the rear bumper departure angle.
Okay, maybe I'll post a new thread. Thanks.

Same here.

In case you go that route, mine's for sale. $180 plus shipping (I recently switched to a bumper)

That's a good price.



As for the weight and stock suspension... I added a BB hidden winch mount, a superwinch talon 12.5, and a Diehard 31m, basically an extra 200lbs. Well a set of shrockworks step sliders too, although they are centered weight. There was noticeable sag in the front end, I had some sweet totally visible negative camber rockin', so much so I didn't drive it but a few times. Those few times were enough to make me push up the date for my suspension upgrade. All of the suspension research I thankfully had done previous paid off, I put new coil-overs on the next week. Solid now = happy :)

I am pretty sure that bumper runs right around 140 pounds, add a winch with synth rope will go about 75lbs, wire rope 95lbs. It will sag, you will not be happy.

No worries. Wasn't trying to be the forum police, but you had enough questions there worth starting a new thread for.
