The seat riser kit was the best upgrade I have made to my 2015 Optima. My wife hated riding in the Optima b/c the passenger seat was too low ( I agree}. Now she has no issues with the Optima's passenger seating position. The kit was easy to install and the quality is great. The shipping was fast. Highly recommended!

Brighter than factory bulbs! Direct plug and play for my 2013 KIA Optima SXL. 10/10 would purchase again!

Quick shipping, nice product.

Very helpful when I had questions. Quick response!

Awesome Store with 2nd to none customer service!!! Thank You!!

Best customer service, shipping and product
