Any difference in them? Who's the best?

 

I've got the SLP line lock (PN 24049) in my car - it works great and was a painless install. The SLP kit includes pre-bent lines for a no-fuss fit in our cars.

Having said that, I'm sure that there's nothing wrong with other manufacturers' line locks, if you don't mind cutting & bending a bit of brake line.

 

I suggest getting a kit with pre-bent lines unless you're experienced with flaring. I have the Hurst kit that I bought from Thunder Racing years ago and installation was straight forward. You'll also want to use a line wrench to remove the tighten the brake line.
