Front SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to stabilize weight transfer and limit body roll while decreasing vibration, stabilizing sway, and softening harsh rebounds. 

The SSF-203-47 has a 1,400 lb capacity when compressed at 50%. The Black SumoSprings shouldn’t be compressed past 65% of their original height in order to keep full memory rebound.

Please Note: SuperSprings International products are specifically designed for vehicles equipped with factory suspension. We cannot guarantee their compatibility with aftermarket products or parts. For questions about fitment on your specific vehicle, please contact us.

Rear's were "EasyPeesie" wheels need to be removed. 15mm for removal & 17mm or 11-16 for the nut, 5mm socket for thru bolt. I found that the "Flat side with the numbers facing the front was the Best orientation. Front, WOW close to a serious pain, removal ha` good wack with probe & hammer. Install,, Not-so, Positioning is Key. Second lube, I used WD-40, good jack control is imperative! Third setting tool. I used a "wonder bar" a softly bent nail puller The ability to apply an even load while (Packing) it in front to rear first, then left & right. Next time I'll look to bend Back the positioning tabs on all but the back side first. Other than the work part, I AM "VERY" Impressed with how my Stock trucks front end is in control from the Git-Go. The enhanced Lateral stability is everything I could ask for.
