Heavy Duty Shift Spring
The stock transfer case shift springs tend to give a sloppy feel to the shifters and can lead to the transfer case shift lever popping out of gear on the trail. We recommend heavy duty shift springs be used with any 4.70 gear set or dual adapter installation. Use two springs for rear transfer case and one spring in the front crawl box. Fits all gear driven, Toyota transfer cases from 1979-1995.
