CV Axle

Hello everyone. I have a 3rd gen tacoma. Im currently running king shocks OEM style. I want to raise them up so i will have a 3 inch lift. But ive read a few thing about having problems with the CV axle after a while along with the CV boot puncturing or ripping. Im running OEM CV axles. I wanted to know what CV axles i should upgrade to that are reliable and can take a 3 inch lift. And without having the boot eventually ripping. Or if i will be fine with running the OEM axles without eventually running into problems or it ripping. Thanks guys.

 

I have yet to see any conclusive evidence that cv axle angle has a measurable effect on cv boot lifetime. However they can be ripped easily by ground debris.

On the other hand, a 3” lift will leave you with minimal down travel (~1” assuming you have extended length kings) which could lead to suboptimal performance. See accutune’s recommended ride height.

 

What the heck?! Okay, this is the internet after all…

OP, you’ll want to make sure the fins (especially the inner ones on the boot closer to the diff) do NOT touch each other at ride height or they WILL rub through in short order, not matter which ones you buy. It’s just physics. Either reduce lift, or loosen the boots clamps and slide out the boot to separate the fins, and re-secure down the shaft.

 

If you have conclusive evidence (not hearsay) that cv axle angle affects cv boot life, please share it.

 

CV angles aside, you should heed the advice of the post above... Your IFS suspension has a limited range of travel, and any lift you add, effectively takes it away from down travel and adds it to uptravel. This means that your shocks will essentially ride at full down stroke (extension) and will never reach full top stroke (compression). End result, your truck will ride like shit and you'll beat the piss out of your Kings.

As recommended, go to the Accutune website and read their articles.

 

I know that friction creates heat. I feel that's enough evidence that cv ribs touching will result in premature boot failure.

OP I reccomend not going higher than 2" of lift. Watch this playlist on YouTube. Gives pretty good information on our ifs to help you better understand how everything works together.

That's a decent conjecture, but without evidence it's nothing more than a conjecture. Also touching alone does not cause heat and/or wear. There needs to be either some rolling or sliding friction between the ribs. There is likely negligible sliding friction, but there could be some non-negligible rolling friction. How much? I don't know.

I also put forward a conjecture that the boots are as or more likely to be damaged by ground debris and that are likely more important things to worry about than cv boots. For example, the life of the CV joint itself is likely affected by the angle of the axle and that is probably a more expensive failure.

 

See @AccuTune Offroad site there tech articles are legit. I recently upgraded to kings ET kept lift at 2” top hat to center bolt at ride height 21” installed length with 700lb coil at 11 3/4” installed length. Talked to dudes on the phone a few times. Great people over there. I have full steel armor winch front bumper. The ride is great and my cv fins are not touching. More height is not the key IMO.

 

More height more problems

 

What if i add just .5 of an inch right now its at 2 inches. The rear of the truck is higher than the front and im trying to atleast get it somewhat more leveled. Im also not trying to lower the rear

 

Oh my another level situation. Do you use your truck as a truck ever? Then you want rake likely more than you currently have. The truck should only be level once loaded.

 

Ok so what if i get some long travel coilovers. I have the medium extended travel and im looking at the long travel for the tacoma but they both look the same. Is there something different internally? Im still trying to achieve a 3 inch lift because the rear of the truck is higher than the front. I dont really do much hauling or put heavy stuff in the back. Its not a work truck but more of a daily driver. Plus i want to put 35s on in the future so i think some extra lift would help a small bit. Someone i met before told me they have a 3 inch in the front abd they have a 4x4. So i want to do the same. Now about the CV axles. Maybe if i seperate the fins from eachother (like said in a post on this tread) maybe if i seperate them they wont rub or rip or whatever. Like i said i met someone before that had a 3 inch lift and has had no problems. Thanks

 

Long travel coilovers(8" travel) will not work. They are meant for longer control arms.

Lifting a truck does not clear tires.

Just do it right and pick your preferred ride height between stock and +2" and cut everything in the way. Also just lower the back.

 

Im not talking about 8 inch travel. I know that forsure wont work. I was thinking maybe something like this would add 3 inches. Both of them look relatively the same. Except for the racing shocks i added to this post. Im pretty stuborn on keeping a 2 inch lift. And im also not trying to lower the rear.

Or maybe this.

But this is what im running

I suggest investigating the youtube link above it has all the info you need. The "ext" travel versions are hardly any longer they will give you a smidge more droop but you can't call it long travel. Really you need the c4 OTF kit if 35's are truly your goal not an extra 10mm longer shaft length.

 

The shocks you linked as being yours are the non-extended version of the shock you linked from accutune. The extended version provides slightly more droop (~1”).

yours: 25001-119A (Non Ext version)
accutune: KRS-25001-119-EXT

The EXT in the part number stands for extended. Note also that King recently discontinued the non-extended version, thus all new shocks are extended, however there are still stocks of the older parts.

Here's a thread on how to fit 35's. It's not about lifting. It's about cutting.

https://www.tacomaworld.com/threads...-those-that-wheel-and-love-alignments.594309/

If you want 35's without body trimming, then you need to start thinking about a drop bracket lift. A drop bracket lift, unlike "normal" IFS lifts, does increase tire clearance. It does this in a similar way that solid axle lifts do, by moving the differential and lower control arm connection points down. The catch is, you have to cut your frame cross member in order to clear the front drive shaft.

 

Ok yeah after you mentioned that i saw the 3 inch is for the 15 tacoma. But im still trying to figure out if there is any suspention out there on the market that will achieve a 3 inch lift. Icon? King? Fox? Etc? Im still wondering. Also i now under stand you dont need more than 2 inches for 35s, but still im trying to lift the front of the truck even if its just a lowsy inch or half an inch. Either way im trying to get it leveled or atleast somewhat leveled without lowering the rear. I currently am really digging the look of how the rear looks for the lift but im not a fan of the front. Like i said if i need to get a different front set up im completely fine with that. But im trying to see if there is ANY suspention that will achieve 3 inch

 

Rake is good IMO.

 

Let's keep things simple. Every adjustable coilover is able to achieve 3" of lift, but is it reccomended? No, because by having the truck sit higher in the coilovers travel you lose out on down travel creating a harsher ride. Spring rate and preload dictate the static ride height. IFS lifts do not create room for bigger tires. If it rubs stock it'll rub with an ifs lift. You don't need ANY lift to fit 35's. What you will need is to cut.

 

You don't seem to be accepting what people are telling you. So, lift your truck 3" in the front and discover for yourself why it's a bad idea.

There is a TON of info on this site explaining why what you're asking for is a bad idea.

It's not our truck and at the end of the day, you may need to learn from your own mistakes, like many of us have.

One last attempt (from me), read this article.
