NOTICE
This mounting kit DOES NOT include hardware for attaching your light bar to
the brackets. Each light bar has unique thread pitch and accepted hardware
depth and there are too many variants on the market to include hardware for
each model. It is critical that you use the hardware provided with your light
bar to attach the light bar to the 4090 brackets. If your light bar did not
arrive with mounting hardware or you need alternate hardware it is the
responsibility of the end user of this product to source and verify proper
thread requirements have been met prior to completing installation. Failure to
use the proper hardware for your lighter can result in damage to the threads
of the light bar housing that may be irreparable and void your light bar
warranty. By using this product you release upTOP from liability claims of
damage to your light bar(s).
Although intended for use with most light bars you might face compatibility
issues during installation. We have tested these brackets on all major brands
with great success. Should you need assistance during installation feel free
to contact us Monday-Friday from 8am to 4pm Mountain time at 720.730.6381 or
email [email protected].
INSTALLATION
Your kit includes two (2) of the 4090 light bar brackets pictured to the left. The brackets are identical and are not indexed as driver/passenger side. ****
First you will need to remove one (1) side hardware set of the front load bar of your roof rack.
- For Bravo and Zulu roof racks you will use a 5/32” Allen wrench.
- For Alpha roof racks you will need to remove the armor first so you will need a 5mm Allen wrench and a 7/16” wrench or socket. An 11mm wrench or socket will also work.
- Gain access to the end of the front load bar and insert two (2) of the threaded inserts into each channel as shown to the right.
- Re-install the front load bar (and armor if equipped).
Next you will install both of the brackets. As mentioned above they are the same part so it doesn’t matter which side you put them on.
- Align the threaded inserts to the holes in the bracket as indicated to the left. Each hole will receive:
- Hex Bolt
- Flat Washer
- Snug the fasteners in place but do not fully tighten. You will need to adjust them into position to align to your light bar.
- Install the second bracket with the remaining hardware using the other two threaded inserts in your load bar.
NOTICE
Use only hardware supplied with your light bar for this step. See front page
of this document for clarification.
- Align your hardware to the slot(s) in the 4090 bracket that are compatible with your light bar. Trial and error will determine which slot works best for your light bar.
- Snug your hardware into place but do not fully tighten to aide in alignment of the light bar later.
- Align and mate the other end of the light bar.
Now you are ready to align your light bar into your roof rack.
- All upTOP roof racks load bars feature depth adjustment in the front location to help zero in the perfect mounting location for your light bar. Simply slide the front load bar backwards or forwards to nest close to your front wind screen. Leave a gap of around .250” (6mm) and remember, the tighter the fit the less wind noise you have to deal with. Some light bars are inherently noisy.
- Slide the light bar brackets side to side to center the light bar in the windscreen. Depending on the light bar you are using you might have collision with the light bar brackets protruding through the angled tabs of your windscreen. You may be required to slide the load bar back further than anticipated to gain required clearance.
- Once your light bar is aligned to your liking tighten all of the hardware with the required tools. For upTOP supplied hardware the torque specifications require 3.5 Ft. Lb.
- Refer to your light bar manufacturer for appropriate torque for light bar related hardware.
