The HD radius arms mount in the factory location with caster adjustment and OE-style rubber bushings, which keeps the ride refinement without sacrificing geometry correction at this height. FOX 2.0 Performance Series shocks are application-tuned for this lift. Two things to address before installation day: confirm whether your engine needs exhaust modification (6.4L definitely does; 5.7L may), and confirm your installer has welding equipment — that's listed as a required specialty tool. Buyers in this generation of Ram 2500 should also confirm their drivetrain is gas, as several trims in the BDS data appear with mixed fuel designations.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003eThis Product Is For You If\u003c\/h4\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eYou own a 2014–2018 Ram 2500 gas engine 4WD in a verified trim configuration.\u003c\/li\u003e\n\u003cli\u003eYou want a 5.5-inch front and 4-inch rear coil spring lift with HD tubular radius arms.\u003c\/li\u003e\n\u003cli\u003eYou want FOX 2.0 Performance Series shocks with application-specific valving at this lift height.\u003c\/li\u003e\n\u003cli\u003eYou want up to 37-inch tire clearance.\u003c\/li\u003e\n\u003cli\u003eYou are prepared to complete any required exhaust modification for your engine type.\u003c\/li\u003e\n\u003cli\u003eYour installer has welding equipment on hand.\u003c\/li\u003e\n\u003cli\u003eYou have confirmed your transfer case type and rear driveshaft configuration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 dir=\"ltr\"\u003eThis Product Is Not For You If\u003c\/h4\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eYour Ram 2500 has a diesel engine.\u003c\/li\u003e\n\u003cli\u003eYour Ram 2500 is 2WD.\u003c\/li\u003e\n\u003cli\u003eYou have not confirmed your engine type or exhaust modification plan.\u003c\/li\u003e\n\u003cli\u003eYour installer does not have welding equipment.\u003c\/li\u003e\n\u003cli\u003eYou want NX2 Nitro Series shocks — see the NX2 variant of this kit.\u003c\/li\u003e\n\u003cli\u003eYou want FOX 2.5 Performance Elite Series shocks — see the FOX 2.5 variant.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 dir=\"ltr\"\u003eProduct Family Reference\u003c\/h4\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eSKU\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eShock Option\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBDS2101FS (this product)\u003c\/td\u003e\n\u003ctd\u003eFOX 2.0 Performance Series\u003c\/td\u003e\n\u003ctd\u003eGas Ram 2500 2014–2018\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNX2 variant\u003c\/td\u003e\n\u003ctd\u003eNX2 Nitro Series\u003c\/td\u003e\n\u003ctd\u003eGas Ram 2500 2014–2018\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFOX 2.5 variant\u003c\/td\u003e\n\u003ctd\u003eFOX 2.5 Performance Elite\u003c\/td\u003e\n\u003ctd\u003eGas Ram 2500 2014–2018\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch4 dir=\"ltr\"\u003eCommon Questions\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eDoes this kit fit the diesel Ram 2500?\u003c\/strong\u003e\u003cbr\u003eNo. The Pro-Ride coil springs are gas-specific.
