Wavetrac Differential, Porsche 915 43T: 911 1978-86, 930 1978-88
Wavetrac Differential, Porsche 915 43T: 911 1978-86, 930 1978-88
The Wavetrac Differential for Porsche 915 transmissions represents a ground-up redesign, engineered to outperform in both durability and traction. It’s a direct-fit solution for 911 (1978–1986) and 930 (1978–1988) models equipped with the 43-tooth ring gear.
Designed with cutting-edge gear technology, the Wavetrac offers optimized tooth geometry for superior strength and enhanced oil film retention. Its compact gear package reduces rotational mass while improving long-term durability. Special focus was placed on reinforcing the side gear and axle interface — a critical area under high power loads.
What truly sets Wavetrac apart is its patented torque biasing technology. While other differentials act like open diffs during zero-load conditions, Wavetrac’s internal cam system generates internal load to keep torque flowing to the wheel with grip — delivering traction when it matters most.
Precision-built in the USA by Autotech Driveline, each unit features:
-
9310 alloy steel gears
-
Case-hardened billet steel housings
-
High-strength ARP fasteners
-
OEM-compatible housing for factory oil cooler mounting
-
A fully transferable Limited Lifetime Warranty
A smart upgrade for classic Porsche performance with modern traction benefits.
