OCT 24 2026

Chris's 3rd gen 2015 Tacoma Sport. Mods before the regear and elocker include
34" Toyos/2" Billstein 5100 shocks/air bags in rear/ecu tune. The addition of 529
Revolution Gears and a recently released new improved elocker really does step
up the game. The text is being added as we speak!

Chris tows this 5000 pound camper once or twice a year....it's been all over
the Southwest and up to Yellowstone National Park.

Let's get right into it. This new elocker has my attention. It has a number
of design improvements over the Harrop/Eaton elockers.

For one, the "stop tab" has been machined into the cap...no more 2
tiny token TIG spot welds.

Also, the rubber grommet for the pass-thru wire is greatly improved. Now,
it installs from the OUTSIDE and has a large surface area for the RTV
sealant to adhere to.

And the internal mechanical improvement is the use of about 12 ball bearings
for the engagement process. No more ramp ring for engagement.

Machine work is high quality yet simplistic.
