Dear Sir:
I have not yet installed the kit. By all appearence the seals are of a very good Quality. The price for as many peices that I got, to me was a very good bargin. I am well pleased. Thanks DP
I ordered one of these kits, but since I hadn't rebuilt a track adjuster before, I ordered another from a Cat dealer in case it was a difficult job; my thinking was I wouldn't want to do it twice if the aftermarket parts weren't up to par. The parts from Cat were 4x the price and the kit was not complete. I used the aftermarket kit in it's entirety and am delighted with the results. I returned the Cat parts for a credit. p.s. I just ordered another one of these in case the other side starts to leak!
