Ditch The White-Knuckle Feeling
- ✕Nose-dive under braking that makes a loaded truck feel loose and unpredictable.
- ✕Rear-end sag & squat with a full bed, a trailer, or a rooftop tent.
- ✕Harsh, bottoming-out ride that slams over every washboard and dip.
Upgrade To A Planted, Level Ride
- ✓Maximum stability through corners and on-ramps, loaded or empty.
- ✓A perfectly level stance the moment you add weight.
- ✓Smooth shock absorption on rough roads and fire trails.
Engineered For Simplicity. Built For The Trail.
🔧
Easy DIY Installation
Replaces your factory bump stops in under 20 minutes with basic hand tools. No drilling, no special tools, no shop.
♾️
Set It & Forget It
The springs sit just above the axle and only engage when you need them — so your empty ride stays factory-smooth.
📈
Progressive Spring Rate
Automatically adjusts to the load. The more weight you add, the stronger it becomes — eliminating sag and keeping you level.
Why Overlanders Run Them
Better Than Air, Metal & Foam
Six reasons Toyota owners trust progressive helper springs over every other fix.
01
Eliminate Suspension Sag
Progressive micro-cellular polyurethane compresses under load to eliminate sag and improve ride quality every time you tow and haul.
02
Stability Control
Improved stability gives you confidence behind the wheel and peace-of-mind safety on the road and the trail.
03
Zero Maintenance
No air lines to run, no pressure to check, no leaks to chase. Set 'em and forget 'em, season after season.
04
20-Min DIY Install
Installs in your driveway with basic tools and skills. Go from install to trailhead in under 20 minutes.
05
Money-Back Guarantee
Not satisfied? If we can't find a solution for you, return them for a refund. If you don't feel the difference, you don't keep them.
06
No B.S. Lifetime Warranty
Built to last and backed for the life of your vehicle. We've got your back as long as you own the truck.

"Towed my camper from Denver to Moab and the rear didn't squat once. Steering felt tighter the whole drive. Wish I'd done this two trips ago."
Cody R.2021 Tacoma TRD Off-Road
✓ VERIFIED BUYER★★★★★
"Full overland build — drawers, fridge, RTT. The back was dragging before. Now it sits dead level loaded and rides better empty than stock did."
Marisol P.2019 4Runner TRD Pro
✓ VERIFIED BUYER★★★★★
"I was skeptical at $85. Installed both fronts in my garage in 25 minutes. First hard brake and the nose just… stayed flat. Sold."
Tyler M.2020 Tundra SR5

Frequently Asked Questions
What vehicles are these compatible with?
A wide range of Toyota trucks and SUVs — Tacoma, Tundra, 4Runner, Hilux, FJ Cruiser, Land Cruiser, and Lexus GX/LX. Check the fitment list above for exact year compatibility.
Will these make my ride stiff when empty?
No. The micro-cellular polyurethane compresses progressively, so it only adds support when needed and keeps normal ride comfort during everyday empty driving.
Is installation difficult?
Not at all. The springs install in the factory bump stop location using basic tools and typically take less than 20–30 minutes. No drilling, no air lines, no alignment.
Do they require maintenance?
None. No air lines, compressors, or adjustments. They work automatically once installed and need zero upkeep for the life of the vehicle.
Will these help when towing or carrying gear?
Yes. They add support when loaded with passengers, gear, or a trailer — keeping the front and rear balanced and planted under load.
What's the warranty and return policy?
Every kit is backed by our No B.S. Lifetime Warranty for as long as you own the vehicle, plus a money-back guarantee — if you don't feel the difference, you don't keep them.
