A 7G-Tronic Clutch Upgrade To Manage Increased Torque

To solve the problem we increased the capacity and number of clutch discs in the K1, K2, and K3 clutch packs. These new discs feature unique friction plates with premium high energy friction material offering exceptional heat resistance and fantastic friction coefficients to handle engine performance upgrades. The K1 and K3 clutch packs have nearly 30% greater friction area while the K2 clutch pack has a whopping 45% greater friction area. This is enough to handle over 1000 ft.lbs. of torque!

Improved Heat Resistance

Separate friction plates and mating plates ensure optimum heat distribution compared to the original single-sided plates. This allows the mating plates to absorb and dissipate heat generated during application and to not degrade friction material. In addition, grooves in the friction plates were made to increase fluid flow through the clutch plates.

Put all that Alpha Power to the ground, order your Alpha Mercedes-Benz 7G-Tronic 722.9 Clutch Upgrade today!

Sleek and classy loafer
Size: 10.5, Color: Black
Was skeptical on this purchase but I have to say, well worth it. Not super expensive but very comfortable. Wears well for summer dress attire for taking your lady out for a dinner or show. Casual yet classy. Not a bad buy.

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.
