Hipshot Grip-Lock Open Gear 3+3 Tuner Upgrade Kit

About This Item

Install modern open gear locking tuners without drilling!
Give your 3+3 headstock a much-needed makeover with the Hipshot Tuner Upgrade Kit. You can install them on any headstock and tuner spacing, without drilling!

Instead of your old, time consuming string change ritual, simply pull the string through the hole and tighten the thumbwheel. A small pin inside the string post will grip your string and lock it in place for worry free tuning!

The patented Universal Mount Plate (UMP) included free in this kit means your tuners will retrofit without drilling or screwing. The special tabs in the plate securely hold your tuning machines in place to make install a breeze!

  • Grip-Lock pin and thumb wheel system
  • 18:1 tuning ratio for super fine adjustment
  • Compatible with 13/32" (10mm) pegholes
  • String post hole fits strings up to 0.060"
  • Set of 6 includes mounting screws, threaded bushings, and washers
  • Cast housing

Also available for 6-in-line pegheads.

These are great!


Verified Buyer

Replaced the Gibson G-Force on my 2015 SG with these. Could not have been simpler and they work great. Really enjoying that the guitar is no longer a neck diver and can be accurately tuned.


Great replacement tuners


Verified Buyer

I bought these for a Gibson SG restoration where the customer didn’t want any new holes in the headstock, but wanted locking tuners. Perfect fit, the high gear ratio makes fine tuning easy, and the open gear look is awesome.


Very Nice Tuners.


Verified Buyer

Due to the mounting plate arrangement, these are easy to install on a wide range of 3 x 3 headstocks. I've had them on and off a whole bunch of Gretsch and Gibson guitars to try them out. While I am not a fan of open gears, they are very smooth with zero backlash. I haven't decided on which guitar will become their permanent home, but I have no regrets purchasing them.


Frighteningly Clever


Verified Buyer

These are high quality and very ingenious and I can't wait to try them on another guitar.

That being said, they have the same problem on my 1994 Epiphone Sorrento as other locking tuners: the headstock on the Sorrento is too thick and the locking posts don't stick through the wood far enough to clear the mounting nut with a standard washer under it. You can leave the washer off, but then the finish tends to crack as the nut is tightened.

I had the same problem with Kluson locking tuners. I love locking tuners for quick string changes and Hipshot quality is legendary, but this is a challenging instrument that I am still struggling with.
