It's the best seller for a reason. With everything needed to properly correct the handling problems heavy Sprinters can experience, our 4.3 kit is the go-to choice for many owners. Whether you are looking for maximum stability in highway travel and treacherous wind conditions, or maximum compliance off pavement, we're able to minimize side to side sway and balance out jarring impacts using our deep knowledge of suspension tuning.
The cornerstone of our Stage 4.3 kit is the 4-corner, adjustable Falcon 3.3 Fast Adjust Shocks with their huge range of compression adjustment available at the simple flip of a large, easily accessed Fast Adjust knob. This allows you to quickly adjust from the softest to firmest settings over a significantly larger range than the competition's smaller adjusters. A larger range of adjustment means the shocks are more effective and adaptable to multiple modes of use.
The rear mini leaf spring pack, tuned specifically to work with the stock rear leaf spring, restores lost ride height and corrects sag while retaining the quiet ride of the factory leaf spring. Typically, 1.25" of rear lift is seen, resulting in a nicely leveled stance.
Our progressive foam Bump Buddy replacement jounce bumpers replace your hard factory rubber bump stops, adding improved spring curve progression, reducing sway, and increasing bottom out resistance without any unnecessary clunking or harshness.

Having installed every suspension manufacturer in the industry. Van Compass continues to be the gold standard. Excellent performance, adjustability and customer service.
Without geeking out on specs and details, the 4.3 that I purchased for my 2021 Revel functions as advertised. Stage 4.3 has the van driving as it was intended. The three shock settings provide noticeable flexibility. I no longer feel as though I will tip over offroad or cross lanes and cause carnage in Montana's cross winds. Novice or pro. Winnebago should not let Revels out the door with it's whimpy MB overweighted stock suspensions. Unbelievable.
I never leave reviews. I felt strongly about how this mod improved safety and performance.
Still being installed, I will have the van next week to learn the difference in handling!
My number one gripe with driving a Sprinter is the white-knuckle driving experience in even moderate crosswinds. I was pleasantly surprised that the 4.3 system completely eliminated my crosswind anxiety. I just completed a 2500 mile journey, getting battered by crosswinds across Wyoming and Nevada and the crosswind assist only kicked in once. This improvement alone was worth the price of the upgrade. Add in a level stance and no more violent rocking when hitting bumps at an angle, and it's well worth the price.
Baja brackets are a pain to install.
