V6 front springs on a 4 cylinder?

All,

Not here to start one of the "what's the difference between the SR5, OR, and Sport" threads.

I've read up quite a bit and have searched online parts databases. The 4 cylinders and V6s (2012) definitely have different part numbers for front springs (SR5/Sport). As a matter of fact, one of the part numbers appears to be the same between the two, but for the opposite side. The OR models are another set of part numbers still.

So with that said, has anyone taken the V6 springs (specifically a Sport) and used them on a 4 cylinder? I'm looking to avoid a significant lift or severely harsh ride.

Why am I considering this? I have to replace some leaking shocks and I'm looking at buying a used take-off set of coilovers as a cheaper and easier solution.

Thanks!

 

Sounds like a reasonable plan. I wonder if you can find the weight difference between the two engines. I have seen ride heights change on old muscle cars swapping springs between v-8 and sixes. If the price is right I would try it. Before you install you will want to note which one is for the driver side to address the tacoma lean.

 

Not going to be much of a difference.

On the AC i4 trucks they use the same spring on the driver side (slightly stiffer) that they use on the passenger side of the v6 trucks. So both springs are going to be ever so slightly stiffer which might net .25-.5in of extra lift on the i4 id reckon.

 

Don't forget the sway bar

 

I have a pair of stock coilovers with 17k on them from a 2014 trdor dcsb if you're interested.

 

I didn't know there was a difference, but this might explain why my truck seems to have a lean since the frame was replaced last month... Are they labeled Right and Left?

I put some OR shocks/springs on my 4-banger and notice the ride is stiffer, but the ride height didn't seem to change. I also replaced the rears with OR's at the same time though.

 

There are definitely two different part numbers. I don't know if the springs are stamped with those numbers, I'm deducing which is which based upon color of the dots painted on the springs. I know one is the same between the V6 and the 4 cyl, just on the opposite side, so I was going to use this as my indicator.

 

Didn't think there was that much difference in weight. Isn't the I4 steel and the V6 aluminum?

 

I completed this job this weekend.

I believe I got the springs on the proper sides, based upon color of the dots and information I had available to me. I started with about 1/4" difference in height and ended with the same.

Overall I gained about 1/2" of height on the front. Rides and feels just about the same.

Cost-effective solution to an unexpected problem, I'm happy.

Thanks all!
