Hellwig 1909 Silent Support System, Special Design Helper Spring Kit

okay- 5 Stars for Hellwig service team for getting me the missing parts I needed. 1 star for the Kitting team. I assume since I seen multiple reviews that say parts are missing there is some training needed over there. However, with one call they got me the parts I was missing without question.Okay important note to All of you couch potatoes to help you help yourself: WOULD YOU WOULD DO A TIMING BELT ON YOUR CAR. ____ YES or NO___If YES - go ahead and buy this kit. If NO then buy this kit and bring it to a shop to install.Installation takes 3hrs-6hrs depending on how your set up in your driveway.Hope this helps you guys.Lift your truck up by your rear end block the front tires. Install jack stands in front of the leaf springs on the frame on both sides. Also put one jack stand under your tow receiver. Release the jack slowly and let the frame rest. still hold your diff with the jack. Tires should be off the ground about 2".Take your tires off if you want it to be safer take one tire off at a time.Unscrew your emergency brake cable bracket as it will be in your way.MARK YOU SHACKLES AND CENTER POSITION WITH SHARPI YOU NEED TO PUT IT BACK EXACTLY IN SAME SPOT.Remove your lower Shock bolt. Leave shock loose.Drop your 4 bolts/U clamps that hold the leaf springs. Electric impact great 80Ft pounds on the way back.Now your axle should be able to drop as low as you need it to go. Lower your jack till you have 5" of clearance between the leaf and the axle. Remove the center 1/2" bolt that holds the leaf pack. Install the longer bolt ( Bolt only)Install your two new leaf springs onto your existing coil springs. Add the nut to the new leaf pack bolt tighten and make sure you still have good vertical alignmentRaise your jack so that the axle goes up and mates with the Leaf pack. Your almost done.Use the clamps as per instruction. Passenger will have the offset U clamp in front and the driver side will have sideways U clamp. The instructions are wrong per Hellwig engineer.Tech Tip: use a ratchet strap like 3000 pond to ratchet your axle back into perfect position where you made your alignment marks. It will most likely need to come forward.Re install your large U bolts that hold your rear diff. Tighten equally at first and mind your alignment marks very important your not 1/4" off. Tighten bolts to 80ft/LBs or your diff will fall the hell offlock tight the bolts since this company does not provide anythingCompress the new leaf springs with 8" C clamp so you can install the clamps on to the leaf springs.If you want to buy Nilocks nuts for the U clamps they are 1/2-20 and 9/16-18 nuts which I will be doing.I would order those before you get this 1909 kit.Reinstall your E brake cable bracket you will need to do some bending as you have a larger taller leaf. And your shock bolt.Once you get the other side down Lower your truck and start to tighten the clamps. I set my leaf spacing at about 1.375" gap and then measured to the ground from multiple points on the truck to get it perfectly equal. If you tighten one side 1/2" more the truck will tilt.There are two different U clamps for the front of the springs. Here is the reason for it. Sideways install by the tank or its may be too close to your tank. Offset larger U clamp on passanger front because your will be right on top of a bracket so you off set to be on the leaf spring.If you tighten to 1.375" you will raise the truck ride height its perfectly fine for me as I tow more then I should all the time. Hope this helps you with the install. As it says up front. This item is not for the guys that bolts on accessories.

Installed these 2500 lb helper springs to level out my 2011 tundra when towing a bumper pull travel trailer. They did the job.Installation is not super easy. The directions are basic at best.Received some wrong/mis manufactured parts. Called helwig and received correct parts in about a week.

You need to read this instructions on the driver side for a 2010 Toyota tundra there's a different bracket for left and right and installation is a different on the driver side than the passenger other than that it's perfect

I like the product and improvement the haulage on my truck

I added these leaf springs to haul my toy hauler without bottoming out my stock shocks. Received the package on time but had missing parts, I called the company and spoke with Kevin; he sent out the parts I needed with next day air and answered all my questions and solved my concerns! Thanks for the help! Great product!!

Install went ok, but that’s the end of the good news.I initially set them on the loosest setting being I’m towing a 5th wheel with less than 1,000lb pin weight. Sagged just like stock.Set the springs as tight as it would go, only helped about 1/4”It did lift the rear 1”, which I didn’t want being I am already lifted and it is over extending my shocks.It also made the ride pretty rough.I had sumo springs before (the 1,000lb version) and they rode much nicer but still sagged too much. I probably needed the 1,500 lb version, but figured these would be a better choice.I ordered airbags and will have to make some modifications to get them to work with my B&W gooseneck hitch.

The new 9/16" x 8" U bolts that were included in the kit were too short after getting the new springs on. Fortunately the old U bolts were long enough I could make them work to put it back together, until I could get to the store to buy longer U bolts. The new U bolts were actually about 1/4" shorter than the stock U bolts that were on my truck.

Wasn't what was pictured totally different install. Took a lot longer since I had to add to the leaf pack not just go over the leafs like in the description. Also with using my truck really didn't notice any more load level then over factory but it did raise my back up about 3/4" from factory.if I had to do it again I would of just spent the extra money for airbags

It was delivered quicker than I expected and went on fairly easy with the help of my son.overall I would highly recommend them...
