Shifter Cable Lockdown for 10th Gen Civics by Alta Performance

Over time, the shift cables in the 10th Generation Civic start to loosen up. This causes a noticeable "double-clunk" while shifting into 2nd, 4th, and 6th gear. This problem is exaggerated when aftermarket short shifter adapters and rods are installed. These annoyances are solved with the ALTA Shifter Cable Lockdown.

The ALTA Shifter Cable Lockdown compresses the shifter mount around the shifter cable, locking it in place, and eliminates the "double-clunk" when shifting gears into 2nd, 4th, and 6th gear. This added pressure prevents the opportunity for noise to occur.

The O-rings mounted to the ALTA Shifter Cable Lockdown act as a dampener by eliminating an additional vibration between the shifter cable and the shifter cable sleeve.

The ALTA Shifter Cable Lockdown is made from lightweight aluminum and is CNC machined for a precise fit. Anodized black and finished with the ALTA logo and part number. While you won€™t see it again once it is installed, know that it will still be looking and working great for many years and miles to come.

Perfect Combo with Perrin Short Shifter

A must have with short shifter

Jeremy Bartelme
Hard install

Took me a few tries and after I chewed up the housing a bit I got it on ok. Also busted one of the 6 rubber bands it comes with just getting it on as the instructions said too. But once it was on it brings all the acuity upgrades together shifts are smooth no clunking no vibration. Then I changed mt fluid to amsol now it's full on love with my shifter! This product is the icing on the cake if you have short shifter or short shift afapter
