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.

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.
