We built this custom four-seat Yamaha YXZ with front and rear straight-axle conversions. Up front, the triangulated four-link uses Summit Machine aluminum links, Wilwood brakes, an ARB locker and full hydraulic steering.
We measured front driveshaft length at compression and droop across 11.5 inches of front suspension travel. With 37-inch tires and the PSC ram in place, the steering took about four turns lock to lock. We observed zero tire contact at compression.
