ELSOBDatsun Posted September 15, 2015 Report Share Posted September 15, 2015 Hey guys and gals, I just got a 521 and wanted to lower it... What the best lowering blocks and size. I was thinking 3"? 2 Quote Link to comment
datzenmike Posted September 16, 2015 Report Share Posted September 16, 2015 I don't think there is a best it's a matter of how low looks good to you. Three inch is fine. You may need to shim the carrier bearing up slightly as lowering will upset the drive shaft angles. BTW welcome to Ratsun, lots of 521s here so feel free to post lots of pictures of yours. 2 Quote Link to comment

flatcat19 Posted September 16, 2015 Report Share Posted September 16, 2015 3" is good. Depending on wheels/tires, it's pretty perfect. 1 Quote Link to comment
Charlie69 Posted September 16, 2015 Report Share Posted September 16, 2015 Adjust rear brakes before adding lowering blocks. Welcome, we need pictures! 2 Quote Link to comment
Loren O Posted September 16, 2015 Report Share Posted September 16, 2015 welcome! I can't wait to see pictures of your 521 ! I will pass along the same advice I was given about lowering. get 720 4x4 rear leaf springs. I am going with a combination of these leaf springs,& 2" lowering blocks. I am also using a one piece driveline from a 520,so no need to worry about the carrier bearing. 1 Quote Link to comment
Charlie69 Posted September 17, 2015 Report Share Posted September 17, 2015 You can take a 1980 720 1 piece drive line and have it cut down to fit. Keep in mind when lowering your 521 that the pinion angle will need to be corrected after lowering. 3 degrees on the pinion angle works great. Quote Link to comment
datson4life Posted September 17, 2015 Report Share Posted September 17, 2015 The lower u go the cooler it looks but more things break, sucks thats chassis hangs too low on the 521 1 Quote Link to comment
banzai510(hainz) Posted September 17, 2015 Report Share Posted September 17, 2015 get belltech part # 6202 is a 3inch 2 deg block . 2deg rake is to keep driveline in line with the trans so no tension on that and carrier bearing then go under truck youll see 2 square like BOLTS. there is a jam nut on back side. loosen the jam nut then turn the bolt outward and the torsion bar will lower. get as far as you can with out taking the jam nut off 2 Quote Link to comment
