Mixing brands may result in uneven lift or handling imbalance.\u003c\/p\u003e\u003cstrong\u003eDoes the RKRRK07015P rear spring support the weight of a full-size spare and heavy rear bumper?\u003c\/strong\u003e\u003cp\u003eRock Krawler designs their JL springs based on a standard Rubicon build configuration with rear bumper and full-size spare. For builds with heavier aftermarket rear bumpers or significant bed payloads, consider Rock Krawler's overland or heavy-duty rear spring options.\u003c\/p\u003e\u003cstrong\u003eIs the RKRRK07015P compatible with JLU models with the heavy steel doors?\u003c\/strong\u003e\u003cp\u003eThe RKRRK07015P is designed for the standard JL and JLU coil spring perch dimensions. Vehicle weight variations from accessories and door choices affect final lift height but do not affect mechanical fitment of the spring.\u003c\/p\u003e\u003cstrong\u003eDo I need a professional alignment after installing the RKRRK07015P rear springs?\u003c\/strong\u003e\u003cp\u003eYes.

The 5-year warranty covers against spring failure and excessive settling.\u003c\/p\u003e\u003cstrong\u003eDoes the RKRRK07015P fit the Jeep Wrangler 4xe JLU?\u003c\/strong\u003e\u003cp\u003eThe 4xe JLU shares the same rear spring mounts as the standard JLU but carries additional weight from the hybrid battery pack.
