OE quality at a fair price

Did my own install in the driveway and it bolted up with zero issues. Has been solid since. Would order again without hesitation. Great experience overall.

OE quality at a fair price

Dropped right in with no modifications needed. Fitment was exact for my vehicle and the build quality feels just like the original part. Will order from Frontline again.

Okay for the price

It works, but I'd recommend confirming fitment with the team first. Mine needed a minor adjustment to seat properly.

Does the job

Fits well and feels durable. Hardware was included. Knocked off one star only because the instructions were a little thin. Will order from Frontline again.
