NOW AVAILABLE: JHM B6-B7 Pre-Built Complete Rear LSD Differential Assemblies!
JH Motorsports is excited to now offer the JHM Rear LSD Pre-Built Rear Differential Core Program. Installing a rear LSD can be simple work, if you have experience and the variety of tools required to properly install an LSD into a rear differential. However, a majority of people do not have that luxury which is why we now offer the JHM LSD Pre-Built Rear Differential Core.
What is a Pre-Built Rear Differential Core? A pre-built core is an OEM Rear Differential that we have pre-installed our JHM Helical Rear LSD into here at JH Motorsports, meaning the customer does not need to perform any specialty work to have our JHM Helical Rear LSD installed in their car. All the customer will need to do is a simple swap of rear differentials and they are ready to hit the road with their new found grip.
Since this is a core program, you will be receiving a Good Used OEM Rear Differential in exchange for yours. We inspect all differential cores when they come in to make sure they are in good working order before they are rebuilt (Some cores may look different than your original differential due to different locations and weather climates). During the installation of the JHM Helical Rear LSD we will also refresh the differential with all new Ringer Gear Bolts, Seals, and O-rings! ALL JHM Rear LSD Pre-Built Rear Differential Cores will come with a 12 Month Limited Warranty as well as a Limited Lifetime Warranty on the LSD itself.

After years of research and development, we are proud to offer our JHM Helical Rear Limited Slip Differential LSD for the Late B6-B7 A4-S4-RS4
In the stock Audi rear differential, the torque from the motor that's sent to the driveline is evenly divided between the two rear axles. In most driving situations this is normally fine. However, in cases where traction is lost at one wheel (i.e. under hard acceleration out of a corner or launching from a stop) power is only being sent to the spinning wheel. In these situations, a gear-based limited slip differential will take the torque from the wheel that's starting to spin and send it back to the wheel with that's not - the one with better traction. This means that both rear tires will spin together - with or without traction.
Features and Benefits of the JHM Helical LSD:
- Helical gears respond to changes in traction conditions very quickly
- Improves traction and predictability of vehicle behavior: both rear wheels will spin at the same rate. Under hard acceleration out of corners or launching from a stop the car will either "hook up" and go or both rear tires will spin. Some "track focused" drivers say that this allows you to steer the car better with the throttle.
- Prevents "one-legging" (spinning one rear tire only) and therefore eliminates losses in acceleration under load out of corners and heavy acceleration from a stop (launching).
- Maintenance free! There are no clutch packs to replace as they wear out.
- No special gear oil or additives necessary. Again, since there are no clutches, you can run the same gear oil as recommended by Audi in our LSD.
- Our JHM Helical Rear LSD comes with a Limited Lifetime Warranty against manufacturer defects.
While we recommend our LSD for anyone looking to improve the traction and predictability of their quattro Audi, the more horsepower your car has or the harder you drive, the more our JHM LSD will make a difference in your car.
