After installing the new rear Sensa-Tracs on my truck, I decided to replace the front ones as well. Received these new Sensa-Trac fronts and put them on with no problems. Now my truck is standing and drives like new. I also submitted a discount form for the Monroe Shocktober discount as I bought four new shocks. I received my discount card today for the price of one category. Wow! That's great. The best shock absorbers at a reasonable price, and one of them is free too. Revan and Monroe are the best.
