Detroit Truetrac – Helical-gear limited-slip (worm differential) is the modern replacement for the classic clutch-type posi. Under normal light throttle driving conditions, a Truetrac operates much like a standard open differential, allowing the rear wheels to rotate at slightly different speeds for smooth cornering.
How strong is the Eaton Truetrac?
The Truetrac designs have been produced within a maximum continuous torque range from 2,500 Lb-Ft to 25,000 Lb-Ft. Increased capacity can be accomplished by larger gears and more pinion sets.
How well does the Detroit Truetrac work?
It stays 100 percent street-friendly and adds increased control in slippery situations while remaining completely safe to drive with in icy road conditions. An LSD can keep a mostly stock axle from grenading when a locker would have broken an axleshaft or worse, and it still very much acts as a traction-aiding device.
Does Truetrac need additive?
Do I need friction additive/modifier? A quality petroleum/mineral based oil works best in the Truetrac units. We do not recommend synthetic oil. Friction additive/modifier is not required.
Is a Detroit Truetrac a posi? – Related Questions
How do you break in Truetrac?
While Truetrac units do not require a break-in for operation, the gears do “lap” together. While the time required to fully lap the gears will vary depending on driving style and loads, the units will operate smoother with age.
Does a Truetrac work in reverse?
The Detroit Truetrac is a helical-gear style, limited-slip differential that maximizes wheel traction and enhances driving characteristics. Maintenance-free, it features smooth, automatic operation in forward and reverse.
Why do you need limited slip additive?
There is a requirement to provide limited slip additives that give excellent friction plate lubrication. The goal of lubricant formulators is to develop new products that retain frictional performance with minimal effect on the thermal stability of the gear lubricant.
What gear oil to run with a Detroit Locker?
A quality petroleum/mineral based oil works best in the Detroit Locker units. We do not recommend synthetic oil. Friction additive/modifier is not required.
How much limited slip additive do I add?
Limited-Slip Axle Additive Concentrate is recommended for use with non-limited-slip API GL-5 gear lubricants to eliminate chatter in limited-slip differentials. The recommended mixing ratio is one fluid ounce of Limited-Slip Axle Additive Concentrate to one pint of API GL-5 gear lubricant.
How does a Harrop Truetrac work?
Truetrac gears have spiral teeth, and the pinions are mounted in pockets in the case. If one wheel begins to lose traction, the pinions separate slightly from the side gear, and wedge in the pockets. As input torque increases, the separating force increases, thus slowing or stopping the spinout.
What are the benefits of Truetrac?
The Truetrac performs like an open differential under normal conditions, and automatically transfers torque to the wheel with the highest traction when required. The Truetrac can transfer up to 3.5 times more torque to the high traction wheel.
How much is a Truetrac diff?
PRICE: $1,173.70
The Truetrac’s proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well.
What gear oil is best for Truetrac?
Always use an 80W-90 mineral/petroleum based gear oil with at least a GL-5 rating. Synthetic oil and oils that contain friction modifiers are NOT recommended.”
Who makes Truetrac differential?
Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque.
What is the difference between gl4 and gl5 oil?
GL-4 gear oils are typically recommended for spur and helical gears found in manual transmissions and transaxles operating under moderate speeds and loads. GL-5 gear oils are typically recommended for hypoid gears in automotive axles operating under high-speed, high-load conditions.
What fluid does Tremec Tkx use?
TREMEC TKX transmissions use the Dexron III or Dexron III/Mercon Spec ATF fluid. Dexron III ATF is also used for the T56 and 3650 models.
How much power can a Tkx handle?
The new TKX 5-speed is an End-Load design. With the gears going in from the back. All this means 600 lb. ft of torque capacity, and with the improved Magnum style syncro design means it can handle shifts at 7,500 RPM.
What is the strongest Tremec transmission?
Tremec T56 MAGNUM-F 6-speed manual performance transmission for the GM applications. This is a bolt-in swap for your 4th-gen Camaro or Firebird. This is the strongest torque/power rating of any 6-Speed transmission ever produced! Rated at a whopping 700 lb-ft of torque capacity.
