i see most kits have 15 to 20 pound units which are realtively cheap but then i see the auto loc ones that are 50 pound and $500 for a four door kit. does anyone here have shaved handles and if so what pound solinoids do you have?
it just depends on what car you have and how heavy your door is, and if you have rusty or sticky latches. for older cars 50lb is sometimes necessary. for minitrucks 20lb is usually used. i've got 35lb on my astro van and it works good. Don't forget your door poppers too!!!
