Sheffield Eagles will play in LHF National League One next season after mauling Swinton Lions 35-10 on Sunday.
After an even opening at Warrington's Halliwell Jones Stadium, Gary Wilkinson's side cut loose to win the League Two play-off final at a canter.
Sheffield full-back Johnny Woodcock scored one of his side's six tries and landed the man-of-the-match award.
Bramley overturned an 8-6 half-time deficit to beat Hemel Stags 30-8 in the National League Three Grand Final.
The Eagles, who go up with champions Dewsbury, dominated the match to record a club record-extending 13th successive win, which made up for their last-gasp defeat by Keighley in the 2003 final.
Their victory was also sweet revenge for their 42-18 Challenge Cup defeat at Swinton earlier this year.
Sheffield went in front with a try from winger Rob Worrincy midway through the first half only for Swinton to draw level when Liam McGovern's kick bounced kindly for right winger Andy Saywell to touch down.
With the scores locked at 4-4, Australian stand-off Brendon Lindsay took an inside pass from half-back partner Gavin Brown and edged the Yorkshiremen back in front with a 38th-minute try.
Woodcock then put them in a strong position in first half injury-time when he stole the ball in a legitimate one-on-one tackle from Saywell to cross for an easy try.
There was no way back for the Lions when Worrincy sprinted the length of the field for his second try after gathering a McGovern kick on his own line.
Centre Jimmy Walker then profited from a slip by Swinton full-back Wayne English to touch down before Andy Hay went through a gap for his side's final try, with Woodcock kicking his fifth goal.
Swinton grabbed a consolation try through centre Dave Alstead, which was goaled by McGovern but Sheffield had the final say when Brown landed a drop goal.
