"These rear helper bump stops enhance Toyota’s factory suspension by adding progressive rear support during compression, helping reduce rear-end sag and body roll when carrying loads, towing, or driving over uneven terrain. The result is smoother suspension movement, improved stability, and a more controlled, comfortable ride while maintaining the integrity of the factory suspension system."

Frequently Asked Questions
What vehicles are these bump stops compatible with?
+
The SSR-623-40 Rear Helper Springs are designed for several Toyota and Lexus SUVs, including Toyota 4Runner, Toyota FJ Cruiser, Toyota Land Cruiser, Toyota Sequoia, Lexus GX, and Lexus LX models. They install in the factory bump stop location to provide additional rear suspension support and improved load stability.
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 rear suspension support when your truck is loaded with passengers, gear, or accessories, helping keep the front end more balanced.
How long does shipping take and can I track my order?
