  • 3/4" DOM sleeve steps up the 1/2" bolt diameter to 3/4", making it much stronger then 5/8" bolts and hardware.

  • Our exclusive design works with both mini tubbed cars and with stock wheel tubs. It does not intrude into the wheel tub area like some designs.

  • Lower edge of box wraps around the frame rail to promote additional strength and ease of installation alignment.

  • Reduced cross section width for lighter weight while maintaining superior strength.

  • Boxes have 1/8 thick welding ledge around perimeter to make it easier to weld to the stock sheet metal areas of the car such as the OEM floor and rocker panel.

  • Inner frame rail side gusset to allow easier access to bolt for adjustment.

  • Adjustment holes will work with a wide selection of ride heights.

Make sure you read the terms and conditions and don't let them off the hook
Asurion is counting on the fact that you don't know how to read. They made the claim process aggravating and as difficult as possible. I CAN read and had to review the terms and conditions with them on the phone and threaten to involve an attorney before they would honor the coverage. They tried to say my product was not portable, when the word "portable" is literally in the name of the product. Then they tried to say the the accidental drop was not covered, but it clearly states in the terms and conditions that an accidental drop and a cracked screen is a covered event. I buy the coverage almost every time I am offered it, but I will be rethinking that going forward and Amazon should consider finding a different company to issue the protection plans for their products because I fear this is the beginning of a lot of complaints. I have filed a claim in the past and it was very straightforward and easy, but they must have a new company managing the plans now, because it was anything but easy. If I was an older person who was not tech savy, or who just took someone's word at face value, I would be out the cost of my item and the protection plan. BUYER BEWARE

Cover yourself!
My HP printer just stopped printing. Spent over 4 1/2 with HP Support doing all kinds of technical experiments with even the most complex Factory Restarts, this printer kept saying everything was working but it wouldn't print. HP finally declared it a hardware defective; told I needed a new printer and to recycle this one (less than 1 1/2 years old - don't make like they used to!). Called Asurion, who immediately processed a claim and arranged for a pickup of the defective printer since I can't drive. Fast quality service worth every penny if you're buying any kind of devices in today's world.

Asurion is a great protection plan.
Asurion is a great product. I purchased a 3-piece cordless phones in 2022 and added the Asurion protection. Just recently the phones went out. I contacted Asurion and within 2 hours I had a gift card deposited in my Amazon account. I purchased new phones with the gift card and of course added the Asurion protection. I highly recommend Asurion protection plan.

Glad we got it! And will most definitely buy it for our future products!
Great experience! We always bought Asurion Protection on a lot of our electronics to be on the cautious side. We recently had one of those electronics give out on its 3rd year, and we luckily had purchased the Asurion Protection Plan. The claims process was easy, took less than 5 minutes. I packaged the electronic the following day and dropped it off with the shipping label they gave me. I received a full refund of my product within hours of having the returned item dropped off. I am glad we bought Asurion Protection for our other electronics, and will continue to buy it for our future products (not just electronics). Very pleased with how fast and reliable they were, and enjoying the comfort of knowing our products are protected.
