These cheap hacks might improve the current situation, however will translate to a poor track time or even a busted differential casing at the end of the day. Product Code: TT917A730. Karanda – Stronghold [Enhanced Progressive], Controlled launches, as both wheels are spinning the same rate, reducing the chances of the car to flick out (RWD) or excessive torque steer (FWD) on power, No single spinning wheels as torque is equally distributed, thus same rotational speed, Controlled power over slides, commonly known as drifting, as both wheels are turning at the same speed when throttle is applied (applies to RWD only), Power output around corners more predictable, instead of having one wheel turning excessively quick. The highest quality differential parts available for race, offroad, or street. Maintenance would be similar to an open differential, Often helical differentials react much quicker than viscous LSDs and do not fade with use as they use gears, Great overall type of LSD but very limited aftermarket choices, Will nearly lock both wheels when throttle is applied, Not a true 1:1 lock as one of the wheels will be spinning a little quicker than the other in most situations, Makes use of hydrodynamic friction from fluids with high fluid viscosity to allow both wheels to turn at nearly the same rate, Will lose effectiveness fluid increases in heat, the effects of both wheels turning at the same rate will fade, Not the best for track, as it can be unpredictable on throttle as both wheels never turn at the same rate (however they appears to), Perfect for street use as it engages gently, makes no noise and off/on throttle transition is smoother, No maintenance is required, as the viscous centre is sealed, Will lock and apply equal force on both wheels on throttle, Will rotate both wheel at the same rate regardless if one is off the ground, Uses clutch packs inside the differential instead of gears or fluid to lock, Requires regular oil changes and once clutch packs wear out, will require replacement and expensive maintenance, Very predictable once driver understands the engagement and disengagement points, Can be hard to drive with for the novice, for the experienced it’s a gift from the gods. 1.30", Eaton Detroit Truetrac Differential, Type: Limited Slip, Ring Gear Dia.
