"Installed these in 20 minutes. First time I hit the brakes hard on the highway I knew it was worth every penny, zero nose dive. Loaded the bed with 600lbs of gear last weekend and the front sat completely flat. This is what the truck should have come with from the factory."

Don’t take our word for it check out what our customers have to say.
Philip B.,
Verified Buyer
Super simple to install and works exactly as described. No more front-end sag under load!
Sarah,
Verified Buyer
Wow what a difference! I’ve got Bilstein 5100s on my 2022 4Runner TRD OR and these fit perfectly. No rubbing once installed, and stability improved massively!
Michael,
Verified Buyer
If you’ve got a 5th gen 4Runner, I 100% recommend these for the front. No need to spend $300 on the other brand when these do the same job for less.
Jessica,
Verified Buyer
After adding these, my FJ Cruiser feels way more controlled on turns and rough terrain.
Roy,
Verified Buyer
They act like an airbag between the spring and frame and provide added stability when loaded. Highly functional and budget-friendly solution!
Jack D.,

Affordable and effective. Does what expensive brands promise at a fraction of the cost.

Handles weight like a champ. Could feel the difference as soon as I drove off.
Frequently Asked Questions
What vehicles are these seat lifters compatible with?
+
They are designed to fit a wide range of Toyota trucks and SUVs including Tacoma, Tundra, 4Runner, Hilux, FJ Cruiser, Land Cruiser, and Lexus GX / LX models. Check the fitment list above for exact year compatibility.
How do the helper springs improve my ride?
+
They add progressive support to your front suspension, helping reduce nose dive during braking, limit sag under load, and keep your truck more stable during turns and uneven terrain.
Will these make my ride stiff?
+
No. The micro-cellular polyurethane compresses progressively, meaning it only adds support when needed while keeping normal ride comfort during everyday driving.
Is installation difficult?
+
Not at all. The helper springs install in the factory bump stop location using basic tools and typically take less than 30 minutes.
Do they require maintenance?
+
No maintenance is required. There are no air lines, compressors, or adjustments — they work automatically once installed.
Will these help when carrying gear or towing?
+
Yes. They provide additional front suspension support when your truck is loaded with passengers, gear, or accessories, helping keep the front end more balanced.
