Looking to install a line lock. Where can I purchase them?

Try Summit or Jegs.

Performance Automotive Warehouse 1 (818) 678-3000.
They have two types 1) HURST Part # HUR-174 5000 @ $120, 2) ROLL-STOP Part #TCI-861700 @ $75.

I'v been useing the HURST for over 5 years and no trouble.

try your local big rig or fork lift supply house. I got my MICO-LOCK there . BTW its a mico lock not Micro lock

So whats the difference between a line lock and a mico lock?

The Mico Locks that I have used are manual. Brake lines need to be plumbed to wherever the manual valve is located, and most of them bleed off. On the other hand the HURST and ROLL-STOP are actuated from a 12 volt sorce via a switch and can be mounted almost anywhere thats convenient.

just a word of wisdom spend the extra money on the line lock that has the stainless valve in it there designed to be used on street driven vehicales ie not used every day the valves sometimes gum up and quit send the extra money

i have heard that the 12 volt ones are prone to solenoid failure that releases the pressure on calipers. only third hand experience but still kinda scary.

Think of your line locks as a short term brake, either as cutting brakes or front/rear. Great if you still have a carb and stall on a steep rock. You don't want to keep them on as an emergency brake, they draw current off your battery while they are energized. The Mico-lock is a manual lock and can hold for longer times without a battery draw down. Once the Mico-lock is plumbed it works great... They both have their applications.

MICO'S ROCK!

I just scored one from the rancho p-n-p last week :D

for a buck:flipoff2:
