Now Wilson Manifolds has added a full range of elbows to its lineup covering everything from 90-105mm throttle bodies.

Now Wilson Manifolds is offering a fully CNC-machined billet elbow that arcs from a 4500-series Dominator-style flange on one end to a 105mm throttle body opening on the other.

Based on RetroTek’s unique, award-winning technology, the Smart Shift system consists of three major components: the backlit billet keypad, a cutting-edge main controller, and the compact actuator.

Finally, the custom actuator was designed by RetroTek to work with over 20 domestic transmissions. The actuator is extremely durable, and shifts are perfectly timed and in-synch with the trans. All mounting hardware is included, and a simple pan-rail design allows for two-bolt installation. The compact Smart Shift system is also compatible with the heavy-duty gear boxes and transfer cases found in off-road racing and rock-crawling, and Smart Shifts have been installed in several pre-runner and trophy endurance race trucks.
