Description
A coil spring works best when its rate and ride-height design suit the vehicle load. ARB part 3136 supplies a rear-axle coil-spring pair with documented applications including 2018–2023 Jeep Wrangler JL two-door.
The manufacturer lists an X5K micro-alloyed spring-steel construction with a durable black powder-coated finish. Its spring-rate specification is 160 lbf/in, and the published free height is 425/415 mm. Pair these springs with appropriate compatible dampers and check installed load and alignment.
