Re: Gear Ratio
Calculator says I have either 1.62 or 1.67 for the diff, pending if i say 2900 or 3000 for 80mph. Running 235 75R15 tires. (seems factory was LR60-15/B on the SPID?)
Which sounds more correct for GM? SPID is GQ1 Other weird codes are XTS YTS and ZTS all stating LR60/15B TBLS HWY R Last edited by Liberty; 03-02-2015 at 06:31 PM. |
