DESCRIPTION
Product Overview
- Factory tailgates on Silverado and Sierra trucks can be surprisingly heavy—especially on HD models.
- This Tailgate Assist Shock Kit adds controlled lowering to your factory tailgate, helping reduce sudden drops and making truck bed access more convenient. Whether you're unloading tools at the jobsite or loading gear for the weekend, the tailgate lowers smoothly and predictably with less effort.
- Engineered specifically for Silverado and Sierra platforms, this system uses vehicle-specific mounting hardware and includes everything needed for a secure installation.
Key Features
- Transforms an abrupt tailgate drop into a controlled and predictable lowering action.
- Specifically engineered to handle the larger and heavier tailgates found on 2500HD and 3500HD models.
- Open the tailgate while carrying tools, materials, equipment, or cargo without needing both hands.
- Includes a nutsert system and installation tool for a solid, reliable mounting point.
- A protective Mylar sheet helps reduce the risk of scratches during installation.
FAQ
Q: Is this designed for heavy-duty tailgates?
A: Yes. The system is engineered to control the weight of both standard 1500 tailgates and larger HD truck tailgates on 2500HD and 3500HD models.
Q: What is the purpose of the included nutsert?
A: The nutsert creates a secure mounting point for the shock system and helps ensure a stable, long-term installation.
Q: Does the installation require welding or drilling?
A: No. The kit is designed for bolt-on installation and includes the hardware needed — no welding or drilling required.
Q: Will this interfere with tonneau covers or bed accessories?
A: In most cases, no. The shock is mounted inside the bed area and is designed to maintain normal tailgate operation. Compatibility may vary depending on aftermarket accessories.
Q: Need a tailgate assist for a Classic Silverado/Sierra or the newer 1500?
A: For 1999-2007 Classic Silverado and Sierra (including 2007 Classic body style), we carry a classic platform kit. For 2019-2024 Silverado/Sierra 1500, check out our newer-generation 1500 kit.

Verified buyerRunning between three rig sites every week, was burning through DEF in about 2 weeks. Getting 6 weeks per jug now. Regen lockouts used to cost me half a day in the field, that's done with.
Chris D.
Verified buyerGot four trucks on the ranch, did this one first to see how it'd go. Eight months in, no codes, pulls hay like she's new again. Other three are getting done before winter.
Travis M.
Verified buyerTowing the boat down to the Keys used to kill me at 11 mpg. Got 15.4 last trip, same boat, same route. Pipe looks stock from the outside, none of my buddies even noticed it's gone.
Mike R.
Verified buyerHauled my horses from Fort Worth up to Amarillo last month, got 17.8 empty on the way back. Was running around 13 before. Pulls a lot better up the grades too, didn't expect that part.
Jason T.
Verified buyerUsed to go into regen every 280 miles when I was loaded down, now I'm pushing 580 with no regen at all. EGTs run way cooler too pulling the skid steer. Wish I had done this sooner, honestly.
Brandon L.
Verified buyerBought it used and the previous guy had wiped the delete history clean. Got everything put back the right way, ran the protocol, passed smog first try. Truck finally drives like it should.

Reversible install
Fitment guaranteed or refundGot questions?
The stuff that keeps you up at night before you commit. Answered in plain talk by guys who actually wrench on these trucks.
A full mandrel-bent stainless DPF and CAT delete pipe, EGR block-off plates and gaskets, DEF delete components, all mounting hardware and clamps, and your preloaded tuner with the custom tune for your VIN. We don't ship anything you don't need, and we don't leave anything out that you do.
No. The custom tune disables the codes the deleted hardware would otherwise throw. Dash stays clean. If a real fault code pops up after install, call our line and a tech walks you through it. Usually it's a sensor that got unplugged during the wrench work, takes 5 minutes to sort out.
We pull your VIN before we ship. Engine, year, trim, cab config, all verified against the kit. If it doesn't fit your truck, you send it back and we either ship the right kit or refund you in full. Fitment is on us, not you. That's why we call it a fitment guarantee.
Most of our customers do. Average install is 2 to 4 hours with basic hand tools, sockets, ratchet, jack stands. You'll get the step-by-step install video emailed after purchase and a 24/7 phone line if you get stuck. If you can change your own oil, you can run our protocol.
Real custom files. Built in-house by guys who've been turning wrenches and writing tunes on Cummins, Duramax, and Powerstroke platforms for years. Every tune is dialed to your year, your engine, and how you actually drive the truck. No outsourced generic tunes pulled off a shared drive.
Once we've got the base files for your platform, dialing it in for your specific truck takes about 20 minutes. Charging $300 for that didn't sit right with us. We'd rather give you the better experience and earn the call when your buddy's truck needs help.
You call us. Real diesel techs, US-based, picking up the phone. We help with install troubleshooting, tune adjustments, fitment issues, codes, anything. We don't disappear after the sale, and the line doesn't go to voicemail. Phone number is at the bottom of every email and on every page of this site.
Yes. The custom tune is reversible, flash the stock file back through your tuner and the truck reads as factory again. The only thing that's permanent is the deleted hardware itself, but most buyers in the diesel community see a properly executed delete as a value-add, not a deduction. We can also ship the OEM-style reverse plates if you want to put the factory exhaust back on for resale.
Lifetime warranty on the stainless delete pipe, no rust-through, no cracks, ever. 2-year warranty on the EGR delete plates, gaskets, and hardware. If anything fails, we ship a replacement same day. The tuner itself carries the manufacturer warranty through EZ Lynk or HP Tuners.
Orders ship from Fort Worth within 1 to 2 business days. Free express shipping anywhere in the lower 48. Most orders land in 3 to 5 days. You'll get tracking the second it leaves the shop.
