Hellwig's medium-duty EZ-990 Helper Springs pack a lot of capability in every box. Packaged complete with the same heavy duty powder coated and plated components, hardware and installation instructions as our heavy duty helper spring products, these kits are designed for the vehicles that need lighter assistance in carrying a load. Simple bolt on design using common hand tools provide the installer ease of installation and the vehicle owner hassle free use. Ideally suited for light towing and loads, these units are fully adjustable using the heavy duty U-bolts included in the kit using simple hand tools. If your tow and haul needs change, simply adjust the heavy duty U-bolts to suit the new load requirements. Once installed and adjusted you are free to haul or tow with greater control and stability. Manufactured with heat treated ASTM 5160 alloy spring steel in our California based facility, these units are rated up to 2,000 lb. level load carrying capacity. They are a great cost effective spring solution and can be adjusted independently for uneven side to side loads.

Shipping Overview

What is your shipping cutoff time? 

Cutoff time for in stock items is 2PM CST for items shipping with UPS.  USPS cutoff time is 10AM CST.   If you need a product by a specific date, please call us to find out if its possible to meet your deadline before ordering. Please be aware that there may be discrepancies with shipping calculators or “in stock” status of a product. 

 

Is shipping free? 

Orders over $149 qualify for free shipping within the lower 48 United States. We will select the most economical shipping option for our free shipping option.  If you'd like expedited service, please select that option during checkout.  Unfortunately, shipping to AK/HI or International we cannot offer free shipping, due to the extra costs incurred.  

 

How long will it take to get my stuff? 

Most in stock orders will ship the same day, if ordered before our cutoff times.  Custom items will ship when they are completed, please inquire for timelines on custom items (as this will vary).  We are located centrally in the US (St Louis MO) - so most items arrive within 2-4 days to the lower 48 US.  You will receive a tracking number when your item ships, allowing you to keep track of it at all times.  

 

I am an international customer, are fees / duties included in the shipping costs?

No, these fees will need to be paid by our international customers.  

 

How can I get a quote for shipping?

Please add the item in your cart and proceed through the checkout process. The system will display all the options we offer, along with a price. 

 

Refund / Exchanges

We have a 30-day return policy on non custom items, which means you have 30 days after receiving your item to request a return. 

To be eligible for a return, your item must be in the same condition that you received it, uninstalled and in its original packaging. You’ll also need the receipt or proof of purchase. 

To start a return, you can contact us at sales@retroshop.us. If your return is accepted, we’ll send you instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted. 

You can always contact us for any return question at sales@retroshop.us.

Damages and issues 
Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.

Restocking Fees 
On non customized (returnable items), a restocking fee of 5-15% may be held from your refund.  Some items are special ordered in for customers, and if we have to return them to our suppliers, we may have a restocking fee for doing so.  If there are any questions on the restocking amount, please email us at sales@retroshop.us.

Exceptions / non-returnable items 
Certain types of items cannot be returned, like custom products (such as special orders or personalized items).  Please get in touch if you have questions or concerns about your specific item. 

Unfortunately, we cannot accept returns on sale items or gift cards.

Exchanges 
Please contact us for any exchanges at sales@retroshop.us.

Shipping Charges
Shipping charges are not refunded.  If you selected our free shipping option, the amount we paid to ship the item to you will be deducted from your return.

Refunds 
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too.
