A quality petroleum/mineral based oil works best in the Truetrac units. No other “special” setup is required. (there are 8 of these worm gears surrounding the side gears. Locking Vs. Limited Slip. There are many factors to consider when determining if a specific differential will last in your vehicle. In racing situations the unit will apply torque to both tires and launch straight as an arrow, time after time. You will not know it is there until you need it. I have to decide on either an Easton posi or Detroit Truetrac differential (I am not interested in a Currie 9" as I spoke to them and they said they have given the ABS/Traction Control market to Moser) Just like the Truetrac it is a helical gear differential but this unit has 6 gears per side vs the 3 gears of the Truetrac. © SoeedMaster is based in Australia.

Also it costs less. Very similar to the Truetrac, but a lot more expensive. If I was going to use something of unknown reputation, I wanted it to be the stongest option available. They are driven by 6 sets of interlocking pinion gears, meaning the stress on the gears is spread out over a greater surface area. Therefore, they are not rebuildable. Unlike our competitors that only use 3 or 4 pinion gears. What kind of break-in is required? When using a 2.881" case, use LM102949/910. Home; About the conference. ... Detroit Truetrac. What does everyone know about this speed master torque worm. The Eaton Detroit Truetrac is a helical-gear style performance differential that maximizes wheel traction and enhances driving and handling characteristics. The unit’s internals will take a little time (depending on driving conditions) to “seat.” Afterwards there will be a slight improvement in its performance. Can I use synthetic? Uncategorized. I eventually wound up with a Yukon grizzly. Distributing torque to both wheels equally is a must for putting that power to the ground whilst also maintaining control of the vehicle’s ability to be steered in the desired direction. As far as I can tell it’s similar to the truetrac, but uses a 6 gear planetary instead of 3. On the street, the operation of the Truetrac will be transparent. I use my car on the street and on the strip, will the Truetrac hold up? Eaton’s TrueTrac was the first LSD to use helical gears over clutches, eliminating the consumable clutches and further reducing the noise of chattering clutches. The truetrac just does what it has to do.. 69 bronco, d44 front , 9" rear, 4.11, detriot tru trac, 4 wheel wilwood disc brakes, hydratech hydroboost, 347 stroker, PS, c4 custom with all billet everything, d20, 3.5" lift, 33x12.50x18, Holley efi, duff long arms, bailie bilt cage.

They are driven by 6 sets of interlocking pinion gears, meaning the stress on the gears is spread out over a greater surface area. The Truetrac operates as a standard or open differential under normal driving conditions, allowing one wheel to spin faster or slower as necessary. But it is more aggressive than the OG Trac-lock diff, so if you like to play in snow/ice you may find yourself in 4x4 more often than not...well when you need to be straight in the road lane instead of sideways through town lol. The … Under normal light throttle driving conditions, a Truetrac operates much like a standard open differential, allowing the rear wheels to rotate at … Can I repair the Truetrac if I need to? It remains the leading helical gear-type limited slip differential in the industry. While this is great for a drag strip, it’s not exactly the best for road racing or street driving where you’re constantly making turns. Give us a try, we think you'll be glad you did! The use of 6 pinion gears means the stress on gears is spread over a greater surface area, reducing the load on all internal components. Need your feedback - pros & cons I am in the process of ordering a Moser 12 bolt for a 95 Firebird. Under extreme conditions (shall we say), I get caught out a bit as it directs the tourqe so quickly - and coz I'm old and the reflexes aren't as quick as they used to be - the car flicks me in the wrong direction every now and then but as I said, only coz I'm too slow to catch it They automatically transferring torque to the wheel with better traction when conditions warrant. I was told the thru bolt alloy3.250 was really good, and get the super daytona pinion support, 1310 yoke, and 3.89 ratio. worm gear ratio and torque information. Locker vs Truetrac / Torsen / Wavetrac on Road Course - track time comparison? But i dont know the whole torque worm stuff. An Eaton Truetrac for the Dana 44; and one being installed in a fifth-gen Camaro rear housing. Creager told us, “the Truetrac differential is the first in the marketplace to my knowledge that had parallel access pinion gears. How much horsepower and torque will the Truetrac take?
