LOAD THE BACK WITHOUT
The Rear Sagging
Pack the cargo area for a week away, add a rooftop tent or hook up a trailer and the back of your 4Runner sinks. The nose points up and your headlights light up the trees. The rear pair takes that weight before the axle hits the stop, so your Toyota sits level and steers like it should. Add the SSF front pair and the nose stops diving too.
Stops the Squat Under Load
A packed cargo area, a roof rack or a hitch on the back, the rear stays up.
Tows Without the Wag
Less bounce and sway from the trailer pushing on the back end.
Keeps Your Beams on the Road
A level Toyota keeps your headlights out of oncoming drivers’ eyes.
Best as a Front and Rear Set
The rear alone fixes half the ride. The SSF front pair stops the nose dive, so both ends finally match.

Saved on worn tires and suspension parts
Owners who run the SSF front pair with the rear get the full result: the nose holds up under braking and the back holds up under load.
Built for Your Toyota
Model and Year
Each spring is packed with millions of sealed polyurethane cells. An empty cargo area barely squeezes them, so the ride stays soft. A full load, a trailer or a big hit squeezes them harder, so the spring pushes back before the axle slams the frame. The SSF front pair is built the same way, so both ends work as one set.
DESIGNED EXCLUSIVELY FOR:
Toyota 4Runner: 2003–2026
Toyota FJ Cruiser: 2007–2014
Toyota Land Cruiser 100: 1998–2007
Toyota Land Cruiser 120 Prado: 2003–2009

UPGRADE YOUR SUSPENSION

Jack Up the Back
Let the axle hang so you can reach the factory rubber stop.
Unbolt the Old Rubber Stop
Two nuts hold it to the frame. A ratchet takes it off.
Bolt On the New Spring
The spring bolts to its steel bracket, then the bracket bolts to the frame in the same holes. No drilling, no cutting.
Load It Up and Test Drive
Pack the back or hook up the trailer. That is when you feel it.

FREQUENTLY ASKED QUESTIONS
Will they fit my Toyota?
+
The SSR-623-40 fits Toyota 4Runner 2003 to 2026, FJ Cruiser 2007 to 2014, Land Cruiser 100, 120 and 150, Sequoia 2001 to 2007, and Lexus GX460, GX470 and LX470. Own a Tacoma, Tundra or Hilux Vigo? You need the SSR-610-40. Message us and we will confirm your fit.
How do they change the ride?
+
They catch the rear axle before it bottoms out, so your Toyota sits level with a full load and squats less when you tow. Paired with the SSF front springs, the nose stops diving under braking too.
Will the ride get stiff?
+
No. The sealed cells barely compress when the back is empty, so everyday driving feels the same or softer. They only firm up when the load or the bump gets big.
Is the install hard?
+
No. The rear pair bolts to the frame where the factory rubber stop was, in about 20 minutes with basic hand tools. No drilling, no cutting.
Do they need maintenance?
+
None. No air lines, no compressor, nothing to check. Install them once and forget them.
Will they help with gear or towing?
+
Yes. The springs carry part of the tongue weight and gear, so the back sits higher and steadier behind a trailer. Add the SSF front pair so the nose stays planted too.
Do they come in different colors?
+
Helper springs come in different colors. Ours come in one color only: blue, built for Toyota trucks and SUVs. There is no color to pick.
How firm are they and how much load do they take?
+
They are progressive. Firm enough to stop squat, dive and sway when you load up, and soft enough that your empty ride still feels stock. The load capacity for your exact part is in the specifications above.
What are they made of?
+
Micro-cellular polyurethane, the same type of material used in heavy-duty and off-road suspension. It is packed with millions of tiny sealed cells, so there is no air to pump and nothing to leak. Unlike factory rubber bump stops, it is not the kind of rubber that dries out and cracks.
How do they handle freezing cold and summer heat?
+
There are no air bags, lines or valves that can freeze, leak or blow out in hot or cold weather. They work the same way in summer and winter, with nothing to adjust.
How long do they last?
+
They are built to last. There is no air to lose, no moving parts and nothing to wear out or maintain. Install them once and drive.
How long does shipping take and can I track my order?
+
Shipping times and costs vary depending on your location and are clearly shown at checkout. Once shipped, you will receive tracking information so you can follow your package every step of the way.
What warranty or protection do I get with my order?
+
Your satisfaction is our priority. If your package is lost or arrives damaged, you may be eligible for a replacement or refund. Orders can be canceled within 6 hours. After delivery, you have 7 business days to request a replacement or refund, no return shipping required. Support team available 24/7.
