ARP Ring Gear to Differential Bolt Kit, T-350/ F5MC1 / A578 Neon, PT Cruiser, Eclipse, & More
Model Number: 221181-ARP-KIT
In 2016, Mopar discontinued the T-350/ F5MC1/ A578 transmission differential bolts. This has left a void for new replacement bolts when swapping a ring gear or differential. Due to the tremendous shock loads generated by launching when drag racing, installing good quality new bolts is a must.
Due to the size, thread cut, and bolt strength of the stock bolt, it is a very unique bolt and we couldn't find an adequate replacement. So, we ended up working with ARP that make the bolts the T-350 customers really need.
Not only are these stronger, but since the heads of these ARP bolts are half of the height compared to the stock bolts, there will be less and hydraulic resistance and aeration in the transmission fluid as the bolts constantly churn the oil when the differential spins.
Reusing used bolts can work but will not have the same strength as the first time they were used. Save yourself from experiencing catastrophic transmission damage by using new ARP bolts. 1 kit does one differential.
High strength thread locker is recommended when installing differential bolts. (Not Included) Torque bolts to 70ft/lb
