Ordered Tein lowering springs. Shipment arrived fairly quick. Overall process was great. Would order from them again.

I ordered a Grant 1103 Steering Wheel, Order Number: 16767. Great prices, quick shipping, good customer service, an all around deal. Thank you.

Great product! Don't even think about another battery hold down - this one is strong, light and has the good looks to boot. Saved over $30 on it too.

price seems fair and as far as I know the quality of the item is good.
