Is there a cost effective solution to add Eloc to a non locking axle vehicle?
I'm trying to stay away from buying a TRD/TRD PRO, but the SR5 doesn't come with a locking axle.
Better to upgrade to a TRD, or retrofit later?
IMO-- Don't bother, I have a Trail with the e locker and have used it very little.
Try ATRAC and if you need more, consider an air locker. Probably more cost effective if a locker really needed.
First, are you absolutely sure you need one. I've done up to level 6-rated trails (10 being Rubicon-ish) with just ATRAC and deflating the tires. More experienced forum members have done even more aggressive trails than that with no locker. If you're absolutely positive you need one because you've been unable to go on a trail, I would consider an ARB air locker. Then you can dual purpose the compressor as on-board air for inflating your tires.
I definitely need one.
I had one of the first FJ's imported to North America and it had the elocker.
The kind of stuff I did (and do), absolutely needed the elocker.
I did the atrac mod and it was nice, but nothing beats manual (electronic) locking axle.
I wish it came with a center lock, rear lock, and a torsen front - but that's a topic for another discussion.
Thank you for your replies.
