Here is what Rancho Engineering sent me regarding replacement bushings for their lift kit. Pretty nice of them to get back with me on this!
[FONT=&]We heard back from Daystar, and they still make the diff bushings. You’ll need to call Daystar directly (1-800-595-7659) with the Daystar part #
Rancho # Description Supplier Part #
RS520039-1 Upper Bushing, Front Differential Daystar #M02387
RS520039-2 Lower Bushing, Front Differential Daystar #M02388
Matthew,
Thanks for your inquiry. Rancho suspension system RS6558B has been discontinued. However, see the information below from Engineering.
RS520041 Bushing – Aft Brace RS520041 – Summit and others
RS520039-1 Upper Bushing, Front Differential Daystar M02387 - check with Daystar or try http://www.valleyspringservice.com/index.php?main_page=product_info&cPath=4&products_id=223
RS520039-2 Lower Bushing, Front Differential Daystar M02388 – check with Daystar. I sent them an email, but have not heard back yet
RS545 End Links RS978 ( 2 bushing kit)- Summit and others
RS520044 Lower Control Arm ( in crossmember) OE or Moog K200155 (must be installed with Loctite 680 retaining compound)
Leaf springs – varies, see below:
We went through a few revisions and manufactures, and left the bushing up to the manufacturer. These came pre-installed form the supplier, but they are all OE GM OR bushings.
Newer springs use RB172 both ends.
If it is an older revision it could be a RB117, or RB231 / RB172
The only difference is the press fit diameter, so he would have to measure that.
Best regards,
Lance
