The Wavetrac Limited Slip Differential (LSD) features an innovative, patented design that improves traction and power delivery in low-grip conditions. Unlike conventional torque biasing differentials, Wavetrac is engineered to maintain effective drive even when one wheel experiences little or no load.
Innovative Traction Technology
The patented Wavetrac design automatically improves traction in challenging driving conditions. Its unique internal mechanism addresses limitations found in conventional gear-type limited slip differentials, helping maintain drive when traction is compromised.
Superior Materials and Construction
Manufactured using high-quality components for exceptional strength and durability:
High-strength 9310 steel gears
Case-hardened forged or billet steel differential housing
Premium ARP fastening hardware throughout
Precision engineering for reliable performance
Maintenance-Free Design
The Wavetrac differential is designed to deliver long-lasting performance without the need for routine internal maintenance or periodic rebuilds under normal operating conditions.
To understand the advantages of Wavetrac technology, it is important to recognise a common limitation of conventional gear-type limited slip differentials.
The Problem: Loss of Drive During Zero or Near-Zero Axle Load
Zero axle-load conditions can occur during normal driving but become particularly noticeable during aggressive cornering, track driving and other demanding situations.
These conditions occur when:
One drive wheel becomes partially or completely lifted from the road surface
A wheel experiences extremely low traction
The drivetrain transitions between acceleration and engine braking
Torque through the differential temporarily approaches zero
Traditional torque biasing differentials can struggle to transfer useful drive during these conditions, potentially reducing traction and vehicle performance.
Most conventional gear-type limited slip differentials, including designs such as Torsen, Truetrac, Quaife and Peloquin, operate by distributing torque between the two drive wheels according to their available traction.
The amount of torque that can be transferred between the wheels is described by the torque bias ratio.
Open Differentials
A standard open differential has a torque bias ratio of 1:1. This means the torque delivered to each wheel is limited by the wheel with the least available traction.
When one wheel loses grip, the amount of usable drive delivered to the opposite wheel is also significantly reduced.
Conventional Torque Biasing Differentials
A torque biasing differential improves upon an open differential by allowing more torque to be delivered to the wheel with greater traction.
For example, a differential with a torque bias ratio of 2.5:1 can deliver up to 2.5 times more torque to the wheel with greater grip than to the wheel with less grip.
This provides a substantial traction advantage during most driving conditions.
However, there is an important limitation.
If one wheel has effectively zero available traction, multiplying that available torque by the bias ratio still produces zero.
2.5 x 0 = 0
As a result, a conventional torque biasing differential may be unable to deliver useful drive to the wheel that remains firmly on the road.
Wavetrac addresses this limitation through its patented internal mechanism, which helps generate the resistance required for effective torque transfer even during zero or near-zero axle-load conditions.
Improved Traction When a Wheel Is Unloaded
During aggressive cornering or uneven road conditions, one drive wheel may become substantially unloaded or temporarily leave the ground.
Conventional gear-type differentials can lose their ability to transfer useful torque in these circumstances.
Wavetrac is designed to continue providing effective torque biasing, helping deliver drive to the wheel with available traction.
Improved Response During Acceleration and Deceleration
When transitioning between acceleration and engine braking, torque through the drivetrain can briefly approach zero.
Conventional torque biasing differentials may temporarily lose their biasing effect during this transition, resulting in a delay before effective torque distribution resumes.
Wavetrac's patented technology helps maintain differential response through these transitions, supporting smoother and more consistent power delivery.
The Wavetrac Limited Slip Differential offers a combination of innovative traction technology, premium materials and long-term durability.
Whether used for spirited road driving, demanding track conditions or performance applications, Wavetrac is engineered to provide improved traction, more consistent torque delivery and greater confidence when conventional gear-type differentials reach their limitations.
