Carli Multi Rate Coil Springs 1994-2002 Diesel

Description

In our multi-rate springs each coil is spaced differently making them a variable spring rate. Initially it is easy to compress these springs for the first couple of inches. As you apply more force, the coils come closer to each other. After a certain point, the coils at the bottom 1/4 of these springs begin to touch each other and finally become inactive or dead, which makes the spring stiffer. The more force you apply to our multi-rate spring the more the rate increases. So, these springs are compliant to very small bumps on the road, while achieving control when needed off road, hard braking, and turning. These springs allow you to achieve the highest performance while driving hard and providing a smooth, comfortable drive the rest of the time. For 2010 trucks, we have found that using a Linear rate coil works best with the heavier 4th Generation vehicles, giving a very supple and smooth ride while still keeping performance to the absolute maximum.

NOTE: the 1994-02 Ram 2500/3500 trucks are notorious for a driver’s side lean up to 1.5″ (lower on the driver’s side than the passenger’s side). Carli Coil Springs and Leaf Springs for the 1994-02 are designed side-specific to lift the Driver’s side more than the Passenger’s side to lessen/eliminate this common lean. However, we’ve had trucks require the taller spring be installed on the passenger’s side to achieve a level stance and trucks that require the same heigh springs be installed on both sides to achieve a leveled stance. These trucks are not an exact science and were designed long before CAD programs and design standardization. For this reason, we cannot guarantee the truck will sit level side to side nor is the corrective action a “warranty”. Our choice was either discontinue the product line OR present the customer with the design oddities so they know what they’re getting into. As there are not many performance options for the 2nd gen trucks, we elected to keep the product line as the side to side correction can be alleviated with the use of small spring spacers with NO performance degradation.
