- Clunks, squeaks and pops can be normal occurrences with coilover setups.
- Mustangs running 9" or wider wheels may require a wheel spacer to provide clearance for coilover.
- 14" spring setups are typically used for drag racing. The extra length of spring may cause interference with street rim and tire setups. Please check wheel and tire clearance!
The suspension bushings included with this part can only be lubricated with PTFE grease, also referred to as "Marine Grease". PTFE grease is a very sticky, opaque grease that is water proof and will not degrade the bushing material. If lubed properly at installation, these bushings will not need to be lubricated again. Use of any other grease on these bushings will cause the bushing to fail and any bushing warranty to be voided.
Engine Mount Fitment Note
Stock and aftermarket engine mounts can have alignment pins that can cause fitment issues. Removal of the alignment pin might be necessary for correct mating of engine mount to k-member.
