Peterbilt Switchmate Series Gen 2

Tired of walking back to the Peterbilt 579 and finding the window down? GEN 2 puts a hinged lid over your window and lock switches. Flip it open when you need it, flip it shut when you step away.

• Hinged lid on stainless steel pins — quick access, nothing to pull off and lose
• Stops accidental window roll-downs and keeps your cab locked when you step away — your dog can’t unlock the truck while it’s running.
• Driver side, passenger side, or both — covers the left and right door switch modules
• Slip-fit — no drilling, no permanent mods, comes off clean
• Carbon-fiber reinforced PETG — won’t warp or melt in a summer cab
• Made in the USA — designed by a working truck driver
• Lifetime warranty when you buy direct from SwitchMate
• Crete Carrier approved — fleet tested, not garage tested
