    The seller initially missed an item in the kit, but they resolved the issue once I reached out. They explained the delay due to their team being at SEMA and quickly arranged to send the missing boot. Although it shipped ground instead of overnight, it still arrived in time for my truck to get out of the shop. I appreciate their effort and positive customer service.

    Great transaction, seller was very communicative and ensured I was ordering the correct parts for the vehicle I was ordering parts for. Parts were packaged well and protected well for ship.

    This rating is for purchase, cust service and description/condition of items. Arrived in a very timely manner, I had a few questions for the seller prior to purchase that they answered entirely and likewise fast. Packaging was very solid and protective (expandable foam insert) so it appears they addressed previous feedback in this regard. Everything that was advertised was included, and in perfect new condition. Will update after installation and a bit of use. So far A+++ experience!! WDDBA!!
