Choosing your Coil Spring Rate
If installing with RCLT HD, here are our recommended spring ratings from RCLT HD Instructions Page 51:
Due to use preferences from Rock Crawling, Baja, Sand, Mud, Snow, & Overlanding, there is no one-spring-rate-fits-all solution and a vehicle may change spring rates a few times during tuning. The goal for Rock Crawling is to have the F&R suspension complement one another, whereby front spring rate is not too high that it causes the rear suspension to be over-worked.
Keep in mind that leaf springs are a progressive rate spring, therefore a slightly higher front coil rate is recommended to compensate. For custom rear linked setups, we have found success in running quite heavy rear coils. For example, BigMike’s 2016 Tacoma weighs 5,100 lbs and runs 550 lb-ft front coils and a rear 3-link with dual spring rate coils configured as a 100 upper and a 275 lower, with the crossover ring (dual rate stop nut) set to 3/4″ above the dual rate slider. In this configuration, the truck has good compliance for daily driving, and as soon as the rear suspension loads, the higher rate lower coil takes over. This keeps high pressure on the front end resulting in a more active IFS, allowing a front tire to be fully stuffed at the same time as an opposing rear. He is tempted to drop to 500 lb-ft front coils, but given his vehicle weight wouldn’t have enough preload to fit 40″ tires, likely resulting in premature spring bind.
| Use Case | Empty Vehicle Weight | Rear Suspension | Suggested Spring Rate |
|---|---|---|---|
| Rock Crawling | 4,500 lbs | Coil | 500 lb-ft |
| Leaf | 500 or 550 | ||
| 4,500 to 5,250 | Coil | 550 | |
| Leaf | 550 or 600 | ||
| 5,250 to 6,000 | Coil | 600 | |
| Leaf | 600 | ||
| 6,000+ | Coil | 600+ | |
| Leaf | 650+ | ||
| Baja / Sand | 4,500 lbs | any | 550 lb-ft |
| 4,500 to 5,500 lbs | any | 600 to 650 | |
| 5,500+ | any | 650 |
Having the right balance between front and rear spring rates is essential to maximize off-road performance
