Which 1 inch Lift Spacer to Use with Timbren Suspension Kit TFR1504E

Question

Question:

I have an extra 1” lift block on the rear and now the ride is not as stiff anymore and when trailer is hooked up it squats too much. What spacer do I need for this kit? The 1/2” bushing or 3/8” bushing one? Thanks

You'd need a 1 inch spacer with a 3/8 inch diameter bushing part # A25723-90AH00 to use with the part # TFR1504E as you have a 1 inch lift and the kit you have has a 3/8 inch diameter bushing.
