Perfect Gear Alignment. Odd sounds, constant grinding noises, and randomly shifting into neutral are the biggest signs of a faulty manual transmission. More often than not, gear alignment issues can result from a bad synchronizer. If that’s the case, you could use the NP231 Transfer Case Mode Shift Synchro Spring. It will readjust the shaft speed and improve gear alignment, contributing to faster shifting and eliminating the noise.
Quality Design. The Crown Automotive NP231 Synchro Spring is built from the best materials to meet OEM specifications and performance standards. This is in line with the manufacturer’s tradition of delivering industry-leading performance upgrades.
Advanced Installation. Note that the NP231 Transfer Case Mode Shift Synchro Spring is sold individually, and you’ll probably need 2 to restore your transfer case to optimum performance levels. Additionally, this is a job best handled by an experienced, certified mechanic to ensure proper functionality and avoid voiding the warranty.
Limited 12-Month Warranty. Speaking of warranty, the NP231 Transfer Case Mode Shift Synchro Spring has 12 months of coverage starting on the purchase date. Depending on the usage rate, it can also be covered for 12,000 Miles.
Application. The NP231 Mode Shift Synchro Spring is a synchronizer spring designed for all 1987-1995 Jeep Wrangler YJ Models with manual transmission.
