70k mile review

We have had the rear big brake kit for some time now and have racked up around 70,000 miles on them so far, and let me tell you they are amazing in all aspects. Great stopping power and the powder coating on the calipers and rotors still look new, I am on my 2nd set of pads so I'm averaging 35k to a set, on a jeep with 10ply 35s and pulling a overland camper ( that does have brakes). Finally about to pull the trigger on the fronts, (going to be going to 37s soon) and im excited to see the results. Thanks alcon

SHUDDER AND SHAKE IS ALL YOU WILL GET AND EMPTY POCKETS

Bought full kit for my Jeep 392, worked great for 2000 miles, now they shudder and shake so bad it is ridiculous, broke them in specifically as instructions stated...were super for 2000 miles, now regret even thinking of buying this overpriced overrated junk! DO NOT BUY YOU WILL REGRET IT!!!! Alco has not returned calls, messages, or emails...they got their money now I am screwed and you will be too!!!!

Hi Ailan,

Sorry for your issues, after we discussed things in greater detail, we found the root issue and I am glad we could work things out - please keep us informed on how things go.

Kind Regards.
