The Baja Designs 447745 is a complete mounting package for Prinsu roof racks, built around seven XL Linkable LED light bars. The manufacturer states that this kit utilizes our 7 Light XL Linkable kit that provides you with a crisp 22,050 lumens. Choosing this kit over a loose light bar means the Prinsu-specific brackets, center support, and harness arrive as one matched system, so you avoid improvised mounting. Owners on user forums report that no vibration or rattle at highway speed was noticed, while wind noise was the biggest issue.
The kit is designed around the Prinsu front-wedge cutout. The Prinsu racks come with the option for a 40" light bar cutout, and the manufacturer's install sheet says if no cutout is present, a centered rectangle can be cut from the top edge of the front wedge panel (1.75" x 42.5"). Per the manufacturer's steps, you remove the center light housing bolts, assemble the center support with an extra driver-side bracket, then pull the side plate on the first two crossbars so six carriage bolts can slide into the front crossbar. The install sheet also calls for with assistance, place the lightbar up to the mounting locations.
Searching for a Prinsu 40 inch cutout LED light bar kit, a Tacoma or 4Runner linkable roof light bar, or a low-wind-noise Prinsu setup? This kit targets those needs directly. Owners on user forums suggest a leading edge trim on the lower edge of the wind deflector as a practical way to reduce noise.
The manufacturer states the kit is meant for Prinsu racks with the 40-inch cutout on the front wedge. If your rack lacks it, the manufacturer's instructions describe cutting a centered 1.75" x 42.5" opening from the top edge of the front wedge panel.
Owners on user forums have reported widening a cutout with a Dremel to fit a wider bar, with one noting they trimmed about an inch on each side. Check the fit against your rack before cutting.
The manufacturer's install sheet lists a 3/16" Allen wrench, a 7/16" socket, and a T30 Torx bit, plus a cutting wheel if your rack lacks the cutout. Work through the center support first, then the crossbar side plates, and have a helper for lifting the bar. Route the light lead through the harness as the sheet directs, and keep wiring clear of hot, sharp, or moving parts.
