Saved me a trip to the dealer
I've bought from the dealer before for twice the price. This was identical quality and saved me a good chunk of money. Great experience overall.

Average, gets the job done
Part works fine but the fitment was a little tight on my vehicle. Double-check your trim before ordering. Once installed it does the job. Decent for the price.

My mechanic said the quality was as good as factory. No squeaks, no rattles, fits like it belongs there. Will order from Frontline again.
