SW Motech makes the light mount kit. It just is a metal brace that is attached bis the existing underside light fairing locations I like it a lot. The Denali D4’s attach right to the mount. Light mount, 1290 Super Adv. S/R/T - SW-MOTECHLove this thread.
How did you mount the Denali D4?
Is there a Denali specific metal mount?
How are you controlling the D4s (conventional relay/switch or cansmart/hexezcan..or?)
Also, what size tire are you running in the back?
