ITS HERE!!! ITS HERE!!! And about bloody time too! Will be installed ASAP! Some original photos have not been recovered yet.

wow im so excited for you

Give us a good review on them! i really want one..

may i ask how much that set u back

how does it work ?? I did a search and found this, it looks pretty bloody good In comparison to other lockers LOKKA uses an amazingly simple method to couple the axles for maximum traction and to uncouple them for full differential action. ie as required when cornering or driving on hard surfaces. The actual principal of it's operation while easily demonstrated is difficult to explain in writing - but is as follows. 1. LOKKA has only 4 main parts - a pair of Driver and a Coupler (side) gears for each axle, there are some springs and pins, some have spacers. 2. LOKKA is normally in a fully locked state and only allows differential action by uncoupling the unit when the ground driven force acting on a wheel (either during turning or when negotiating obstacles) forces that wheel to turn faster than the other driven wheel. ie a turning vehicle's wheels actually travel two different paths with the inside wheel turning in one circle while the outside wheel travels in a larger circle, and therefore faster. 3. LOKKA makes use of two distinctly different sets of opposing forces that exist due to its design - one to dynamically couple the gears when engine torque is applied and the other to uncouple the gears when one wheel overruns. 3a. The locking (coupling) force is applied by the action of the pinion cross shaft acting on a uniquely designed and shaped Driver - the more torque that is applied the harder the unit locks. 3b. The unlocking (uncoupling) action occurs due to the ramping effect between the low profile ramped teeth which force the Driver away from the Coupler (side gear) eg when an outside wheel turns faster than than an inside wheel when cornering. Power continues to be applied to the inside axle. As the turn is completed and the wheels again rotate at the same speed, the outside coupler re-engages. 4. It should be understood that only when there is an external force being applied to a wheel to make it turn faster than the rest of the drive train will LOKKA allow one wheel to differentiate. Slippery surfaces where one wheel would normally break traction in an open diff cause LOKKA to stay locked - even with one or both wheels in the air LOKKA will remain locked.

Looks neat, where can we get them and how much do they cost. Will these on 25 spline axles cause the axles to break?

It's amazingly simple when you've got it in your hand trust me! The cross shaft pushes the cam gears apart under engine torque forcing the dog teeth to engage. When cornering the cam gears come back together and the apprpriate axle gear disengages from the cam gear. The axle gear cannot re-engage until the cam gear is spaced out by the cross shaft due to coming into contact with the central spacer. Bascially the central "spacer" is the only part actually attached to the carrier, and everything else simply "floats" around it and is affected by the forces of the cross shaft.

is this similar to a 2 way differential?

I had one of these in my car for about 1yr, Very good for traction, but always had issues of diff tramp and never solved it. 1 thing tho always locked up, never single spin once. Also to much backlash for my liking. There orrite tho for a quick fix.

I run a detriot locker in my VL rally car and it is awesome. Is noisey when it is ratcheting though (when you turn without any throttle on) but I do not care. Would sh!t me in a road car though.

Also to much backlash for my liking. There orrite tho for a quick fix. In what car? This is a new design for the Borg Warner that was only made available about 4 weeks ago. It uses dog teeth driven side gears, not the original side gears like the old BW design. Diff tramp should be solved by my adjustable upper trailing arms hopefully.

from how it looks to me, when a gear is dissengaged it's going to slip on it's self? how loud are these?

i still dont really understand how it works, like i understand the theory, just cant see it practically.

Quote: Originally Posted by E-Z i still dont really understand how it works, like i understand the theory, just cant see it practically. Me neither! Lol I understand how it locks, and stays locked, by action of the cross shaft. But unlocking is just due to the profile of the dog teeth somehow.

for an extra $200 you could have had a 28 spline LSD rebuilt... whatever tickles your pickle i guess

But I'd prefer not to waste my money and effort rebuilding the thing every time it started single wheeling. These were designed because the Borg Warner LSD's are known for being absolute junk, so it was the logcial choice.

whats the part number and stockests???
