Broken Coil Spring - TRD Pro Suspension/6112 - Common or Rare?

Where is the "is it surface rust? Yes or no" option on your poll?

 

Things break, especially in the NE, replace it and move on. I had broken leafs in the back and 2/4 busted shocks from rust and wear on a Tacoma I got from the NE. Replace it and move on.

 

That spring has been broke a while for there to be that amount of rust in the broke area. If that was recent, then you should see clean steel with maybe some minor rust where the crack originated.

Rust is a factor. Looking at the picture, you have rust scale coming off in chunks.

 

yes it is

The rust inside the break looks worse due to the jagged surface of the metal. The rust on the springs is purely surface rust, but the shit has been broken for several months and is eating the stuff inside the break.

 

I am selling my 600lb springs off of my 6112's if anyone wants them.....

Agree with original poster... Looks to me like a stress fracture caused by the end of the spring creating a stress riser where it's not tapered, then the rust came after. That bare uncoated metal on the inside of the coil can rust quick.

My dad's tacoma with TRD had almost the exact same failure, sure a little surface rust but you can see the metal on the inside of the stress fracture is clean. Look at any spring on any old car, it will have surface rust (esp if you live in Michigan). That's absolutely no excuse for a spring failure! And this 60k truck has barely seen a pebble. Bad design.

 

Rust (corrosion) causes pitting, pitting creates stress points and stress points lead to cracks. IE a Cessna 210 wing spar issue

I had one break, too. It happens. This Emu only had 10k and no wheeling before it broke.

 

Looks like a common problem for the FJ TRD as well. Not sure if somehow related. Maybe it's just the red paint

yes found my drivers side spring broken today, found piece laying on garage floor or i never would have know it,, anyone know where to get a replacement spring ?? thanks,

 

For a 600lb spring? I have my old ones for sale. They have about 15,000 miles on them. I upgraded to 650lb ones. $50 plus shipping if you want.

 

Since I need to replace my aging shocks and was debating on sticking with old springs or getting fresh new ones, now I gave to pay attention to the design and look for a nice taper

 

anyone know where i can get a replacement coil. ? thanks

 

Is it the 600 lb spring?

 

I have my old 600lb springs that will fit into the ro suspension since it is the same shock. I upgraded to the 650 lb springs at 15000 miles. A this point, I am willing to donate them if you need them, just pay it forward.

 

for non OEM, these folks are friendly: https://www.tacomaworld.com/forums/headstrong-off-road.193/

 

i have no idea what lb. spring or length i need... Trd Pro fox shock. 2017..

 

OH, you have the TRD Fox shocks. I have ones that fit the bilstein 6112's.

 

Same thing just happened to me. About 3.5 years and 50,000km on them.

 

Fox's or TRD Pro Bilsteins? If they are the Bilstein ones, I have my 600lb ones from my 6112's (exact same spring) that you can have for free. All you would need to pay is shipping. They have 15k one them
